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.

SW25Needle roller bearings are equipped with thin and long rollers (roller length is 3-10 times the diameter, and the diameter is generally not greater than 5mm), so the radial structure is compact. Its inner diameter size and load capacity are the same as other types of bearings, and its outer diameter is the smallest, making it particularly suitable for support structures with limited radial installation dimensions. The machining accuracy and surface quality of needle roller bearings should be combined with the bearing ring and purpose according to different usage scenarios. Needle roller bearing is a bearing unit composed of radial needle roller bearing and thrust bearing components.

4、 Product physical picture

Model:SW25

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

Bearing characteristics:
An important characteristic of printing machine bearings is their low friction torque and low operating temperature. Usually, the working temperature of bearings should not exceed+60 ° C to prevent adverse effects on the printing process.
Cylindrical roller bearings have low friction, which is beneficial for high-speed operation of printing machines.
The friction torque and temperature rise of bearings are influenced by the following important factors:
1. Bearing type
2. Bearing size
3. Speed
4. Load capacity
5. Bearing clearance
6. Lubrication
7. Application scenarios
8. Sealed.
Lubrication has a significant impact on the operating temperature of bearings. The use of special high-performance lubricating grease can greatly reduce the working temperature of bearings compared to oil lubrication.
Therefore, it is necessary to carefully determine the amount of lubricating grease during initial lubrication and re lubrication based on the type of bearing.

Bearing function
In terms of its function, it should be support, which literally means it is used to support the shaft, but this is only a part of its function. The essence of support is to be able to bear radial loads. It can also be understood as being used to fix the shaft. The automatic selection of quick and easy bearings is included. It is to fix the shaft so that it can only rotate, while controlling its axial and radial movement. If the motor does not have bearings, it cannot work at all. Because the shaft can move in any direction, and the motor requires the shaft to only rotate during operation. In theory, it is impossible to achieve the function of transmission. Moreover, bearings can also affect transmission. In order to reduce this effect, good lubrication must be achieved on the bearings of high-speed shafts. Some bearings already have lubrication, called pre lubricated bearings, while most bearings must have lubricating oil, which is responsible for not only increasing energy consumption due to friction during high-speed operation, but also easily damaging the bearings. The notion of converting sliding friction into rolling friction is one-sided, as there is something called sliding bearings.

How to ensure reliable operation of bearings:
1. The bearing clearance should be appropriate. If it is too large, it will cause impact, while if it is too small, it will result in poor lubrication and may burn the bearings;
2. The surface quality and geometric shape of bearings and shaft necks should be strictly guaranteed;
3. Improve lubrication quality, control oil pressure, temperature, and flow rate, and strengthen oil filtration;
4. Use fuel and lubricating oil that comply with regulations.

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.
