1、 Brand Overview

When it comes to the INA brand, many people may think of INA bearings, but they are not very familiar with them. Let me now explain the INA brand knowledge to everyone!
INA: is a well-known bearing brand in Germany, belonging to the German INA Bearing Company under the Schaeffler Group. It was founded in 1946 and is headquartered in Nuremberg, Germany. Since its establishment, INA Bearing Company in Germany has been committed to product innovation to meet customer needs and provide high-quality assurance, making it the world's leading supplier of rolling bearings and a recognized partner for automotive manufacturers. Bearings are an important component in contemporary mechanical equipment. Its main function is to support mechanical rotating bodies, reduce their friction coefficient during motion, and ensure their rotational accuracy. According to the different friction properties of moving components, bearings can be divided into two categories: rolling bearings and sliding bearings. Rolling bearings have been standardized and serialized, but compared to sliding bearings, they have larger radial dimensions, vibration, and noise, and are also more expensive.

As early as 1946, George? Dr. Georg Schaeffler and his brother Wilhelm co founded Schaeffler Corporation and demonstrated the significance of breaking through thinking frameworks in 1949. At that time, his research and development of needle roller and cage components led to a major breakthrough in the application of needle roller bearings in the industrial field, filling the gap in this field. George? Schaeffler's innovative spirit and desire for success have become an eternal part of INA's corporate culture in 35 factories worldwide. For decades, INA has represented creative solutions, professional standards in design and production, and great attention to customer requirements. Breaking free from the constraints of thinking patterns, breaking through the obstacles of traditional habits, and finding new ways, whether from the beginning of a company's establishment or decades later today, are all the essence of corporate culture.

2、 Product Introduction

Definition of bearings:
A bearing is a component that supports a shaft, which can guide the rotation of the shaft and also withstand the idle parts on the shaft. The concept of a bearing is very broad. The component that supports the axis of relative rotation is called a bearing. Usually, it is axis rotation. There are also cases where the shaft does not rotate but the housing rotates, such as car wheel hub bearings. Bearings are the foundation of all machines and an indispensable product in modern society; Known as the "grain of the machinery industry", it ensures the quality of all supplied products and the normal operation of equipment. Tongqi Bearing specializes in providing services for industrial production and automotive maintenance; Specializing in imported brands, gathering classic bearings from various countries, consolidating the comprehensive strength of each brand, and continuously providing technical services to users and distributors; Assist customers in solving difficult problems such as bearing selection, domestic and foreign brand exchange, and model specification substitution; In the market economy of the new century, helping enterprises reduce costs, provide economic benefits, and ensure worry free operation of equipment.

Printing machine bearings are used for central positioning of plate cylinders, rubber cylinders, impression cylinders, and transfer cylinders. This means that bearings should meet a series of requirements as much as possible. The accuracy of roller bearing arrangement has a decisive impact on printing quality. The bearings of the printing machine must ensure that all cylinders can work together to the best extent during the printing process. There must be no relative motion in the radial and axial directions. Therefore, bearings must meet high requirements in terms of zero clearance, rigidity, and operational performance. Moreover, it must be possible to control the axial movement of the printing plate cylinder to achieve skew adjustment (diagonal alignment function).

5、 Product Details

The form and function of bearing washers and gaskets
The main type of bearing sealing refers to the installation of devices with sealing effects on the two end faces of rolling bearings. Bearing sealing has gradually entered people's vision with the development of industry, and it is a technology that has only been valued in recent years. Before the development of bearing sealing, all bearings were open type bearings.
Form of bearing seal:
The sealing ring structure of bearing seals varies, resulting in differences in sealing effect. A non-contact bearing seal is a type of seal that leaves a gap between the sealing ring of a bearing and the shaft. The smaller the gap, the better the sealing effect. However, reducing the gap will lower the allowable rotational speed of the shaft. Conversely, the larger the gap, the worse the sealing effect and the higher the allowable rotational speed of the shaft.
A contact seal is a type of seal in which there is no gap between the sealing ring of a bearing and the shaft. The bearing seal adopts a contact sealing type, and the contact lip of the sealing ring and the contact surface of the shaft determine the sealing effect. The larger the contact surface, the better the sealing effect, but the lower the allowable speed of the shaft. Conversely, the smaller the contact sealing surface, the worse the sealing effect, but the higher the allowable speed of the shaft.
Function:
The bearing seal keeps the interior of the rolling bearing in a basically isolated state from the outside world. The loss of various lubricating oils and grease substances added inside the rolling bearing is minimal, and the lubrication effect is greatly improved. Therefore, the bearing seal can largely maintain the lubrication state of the bearing.
Another function of bearing sealing is to isolate the contact between various substances inside the bearing and the outside world, reduce the probability of dust, harmful gases and other substances entering the bearing cavity, and reduce various damages caused by impurities inside the bearing. In this regard, bearing sealing can relatively improve the service life of bearings.

What method is used for positioning the inner and outer rings of bearings?
In order to prevent axial movement of the bearing under axial load, axial positioning devices should be used on the shaft and in the outer Nanning hole of the bearing. The selection of the positioning method for bearings on the shaft and in the housing hole depends on the magnitude and direction of the load acting on the shaft, the speed of the bearing, the type of bearing, and the position of the bearing on the shaft. The greater the axial load, the higher the bearing speed, and the more reliable the axial positioning should be. The axial positioning method should also be different for different types of bearings. Diagonal contact ball bearings and tapered roller bearings can use one-way support with shoulder and housing holes, without the need for specialized positioning devices. The axial movement of the ring can be supported by the bearing itself. As a fixed support radial bearing, its inner and outer rings must be fixed to the left support in the axial direction. As a movable support that needs to compensate for the thermal elongation of the shaft, when installing non separable bearings, only one of the rings needs to be fixed, and the movable ring is not fixed. When installing separable bearings in a moving support, such as short cylindrical roller bearings and needle roller bearings, both rings need to be fixed.

The commonly used positioning methods for bearing rings are now introduced as follows:
One When installing the bearing inner ring on the shaft, it is generally fixed on one side by the shaft shoulder, while the other side is fixed with nuts, stop washers, or spring washers. The dimensions of the contact part between the shoulder and axial fixed parts and the inner ring of the bearing can be determined according to the installation dimensions of various types of bearings listed in the bearing size table.
(1) When the nut is positioned at high bearing speeds and subjected to significant axial loads, the end face of the nut in contact with the inner ring of the bearing should be perpendicular to the axis of rotation. Otherwise, even if the nut is tightened, it will damage the installation position and normal working condition of the bearing, reducing the rotational accuracy and service life of the bearing. Especially when the fit between the bearing inner hole and the shaft is loose fit, strict control is needed. In order to prevent the nut from loosening during rotation, appropriate technical measures to prevent loosening need to be taken. Using a nut and a stop washer for positioning, insert the key teeth inside the stop washer into the keyway of the shaft, and then bend one of the teeth on the outer ring into the notch of the nut.
(2) When the axial load on the bearing is not significant, the speed is not high, the shaft is short, and it is difficult to machine threads on the shaft neck, a rectangular elastic retaining ring can be used for positioning the spring retaining ring. This method is very convenient for loading and unloading, occupies a small space, and is easy to manufacture.
(3) When the thrust washer is located on a short shaft neck, it is difficult to process the shaft neck into threads, and the bearing speed is high and the axial load is large, washer positioning can be used. That is, two or more screws are used to position the washer on the shaft end face, and a stop washer or wire is used to tighten it to prevent loosening.
(4) The fixed sleeve positioning bearing has a low rotational speed and can withstand stable radial loads and small axial loads. The self-aligning roller bearing can be installed on the optical axis with the help of a tapered fixed sleeve. Tighten the nut and stop washer for positioning. Use the frictional force of the nut lock to position the bearing.
(5) When installing bearings with tapered inner holes on tapered shafts, it is necessary to check the axial load and tighten the shaft and bearing. Therefore, attention should be paid to the directionality of the tapered inner hole during installation. If the bearing is located at the shaft end and can be machined into threads at the shaft end, it can be directly positioned with a nut. If the bearing is not installed on the shaft end and threading is not allowed on the shaft. In this case, the threaded ring with two halves merged can be clamped into the groove of the shaft, and then the bearing can be positioned with a nut.
(6) In certain special situations where the shoulder and fillet dimensions of the shaft cannot be determined according to the installation dimensions listed in this catalog, transition washers can be used as axial supports.

II When installing the outer ring of the bearing in the housing hole, there is usually a shoulder fixed bearing position on the inner side of the housing hole, and the other side is positioned with end caps, threaded rings, and elastic stop rings.
(1) End cap positioning is used for all types of radial and angular contact bearings, and is used in situations where the bearing speed is high and the axial load is large. The end cover can be positioned and pressed against the outer ring of the bearing with screws, and can also be made into a labyrinth sealing device.
(2) When the speed of the threaded ring positioning bearing is high and the axial load is large, and it is not suitable for using end cap positioning, threaded ring positioning can be used for radial bearings and thrust bearings, which can be used to adjust the axial clearance of the bearing.
(3) The positioning method of elastic gear ring occupies a small axial position, is easy to install and disassemble, is simple to manufacture, and is suitable for bearing small axial loads. Add an adjusting ring between the bearing and the spring to facilitate adjusting the axial position.
(4) Deep groove ball bearings with stop grooves on the outer ring of the bearing can be positioned using stop rings. When the stop shoulder cannot be machined in the housing hole due to limitations in conditions, or when the component must be reduced in contour size, this type is selected

Installation steps
Before installing the bearing on the shaft, it is necessary to first remove the fixing pin of the bearing sleeve, polish the surface of the shaft neck smooth and clean, and apply oil to the shaft neck for rust prevention and lubrication (allowing the bearing to rotate slightly on the shaft).
2. Apply lubricating oil to the mating surface between the bearing seat and the bearing, and install the INA bearing into the bearing seat. Then fit the assembled bearing and bearing seat together onto the shaft Push to the desired location for installation.
3. Do not tighten the bolts that fix the bearing seat yet, but allow the bearing sleeve to rotate within the bearing seat. Install the other end bearing and seat on the same shaft, rotate the shaft a few times, and let the INA bearing automatically align itself. Tighten the bearing seat bolts again.
4. Install the eccentric sleeve. First, insert the eccentric sleeve onto the eccentric step of the bearing inner sleeve and tighten it by hand in the direction of the shaft rotation Then insert or press the small iron rod into the counterbore on the eccentric sleeve Use a hammer to strike the small iron rod in the direction of axial rotation Install the eccentric sleeve firmly, and finally tighten the hexagon socket screw on the eccentric sleeve.
