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

SB50Needle 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.

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.

4、 Product physical picture

Model:SB50

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

What are the reasons for the failure of roller needle bearings?
There are many reasons for the failure of roller needle bearings, and all the influencing factors in the design and manufacturing process are related to the failure of the bearings, which is difficult to analyze and determine. In general, it can be considered and analyzed from two aspects: usage factors and intrinsic factors.
The usage factors mainly refer to whether the installation, adjustment, maintenance, repair, etc. meet the technical requirements. Installation conditions are one of the primary factors in use. Improper installation of bearings often leads to changes in the stress state between various parts of the entire bearing system, causing roller needle bearings to operate abnormally and fail prematurely. According to the technical requirements for bearing installation, use, maintenance, and upkeep, monitor and inspect the load, speed, working temperature, vibration, noise, and lubrication conditions that the bearings are subjected to during operation. If any abnormalities are found, immediately identify the cause and make adjustments to restore them to normal. In addition, it is also important to analyze and inspect the quality of lubricating grease and the surrounding medium and atmosphere.
1. Causes of high temperature phenomenon in bearings:
(1). It is possible that the cooling water of the bearing has been interrupted, causing a high temperature phenomenon.
(2). It is possible that the oil quality of the roller needle bearing has deteriorated, the oil itself is not clean, or the oil has deteriorated during operation. If the moisture in the oil increases, it will cause an increase in the acidity of the oil, which will reduce the lubricating effect of the oil, corrode the bearing shell, and thus cause an increase in bearing temperature.
2. How to deal with the impact of high temperature of roller needle bearings:
(1). The alarm bell will ring
(2). The fault light sign of the turbine machinery on the machine side panel lights up, indicating that the instrument temperature of the bearing has increased, and the signal relay is activated.
(3). The black needle of the thermometer dial (expansion thermometer) overlaps with or exceeds the yellow needle.
(4). Send a fault signal indicating an increase in temperature of the roller needle bearing.

Precautions for INA bearings:
There are many things to pay attention to in INA bearings, and if these precautions are taken well, it can ensure that the service life of INA bearings can be within expectations. But if the areas that INA bearings should pay attention to are not addressed, it is likely to reduce the service life of INA bearings, directly affecting the service life of mechanical equipment. INA bearings have many different types and applications. If we pay attention to the areas that need to be noted for INA bearings, we can ensure that they can be effectively resolved in the event of a malfunction. When INA bearings fail, it is usually not simply caused by one aspect, but rather by a combination of multiple factors. So in the process of using INA bearings, if there is a malfunction, attention should be paid not to consider it unilaterally, but to comprehensively consider multiple factors. If we only consider the reasons for the failure of INA bearings from one aspect, it is often easy to overlook certain important issues and cannot solve the fundamental cause of the failure. If this continues for a long time, it will only treat the symptoms and not the root cause. Therefore, if we want to know the cause of the failure of INA bearings, we must pay attention to the overall consideration of the reasons for the concerns. Additionally, it should be noted that during the operation of INA bearings, both the internal and external parts will experience some degree of friction due to rotation, resulting in some degree of wear and tear on both the internal and external parts of INA bearings. So when the INA bearings are running, it is necessary to control the application of lubricating oil between the INA 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.
