Thin-wall constant section bearing is also called thin-wall ring bearing. They are highly accurate, very quiet and have a strong load carrying capacity. Thin-walled ring bearings can be deep groove ball bearings, four-point contact bearings, angular contact ball bearings, and thin-walled constant section bearings are mostly square. In these series, the cross section remains the same even with larger shaft diameters and bearing holes. Therefore, these bearings are called thin-walled constant section bearings. It is this characteristic that distinguishes the standard ISO series thin-walled ring bearings from conventional bearings. Therefore, without changing the shaft diameter, a larger cross-section can be selected and a bearing with a higher bearing capacity can be used. Thin-walled ring bearings can be designed to be very light. Bearings that require very little space.

In recent years, the market demand for symmetrical cross-section thin-wall bearings has been increasing, and the momentum is good. However, a large number of products of different brands enrich the market, and the good products are uneven. Consumers will encounter many problems in the process of use. In order to solve these problems, our company here to provide you with some solutions, I hope to be useful to you.

1. Reasons for the decline of sealing performance of equal-section bearings.

The phenomenon is: the friction torque is large. Dustproof, dustproof and other performance is not good.

The reason is that the special bearing structure: thin wall, small volume, light weight, small sealing space, poor rigidity, easy deformation and so on. Bearing parts, including seals, hot processing, cold processing, testing brings great difficulties, it is difficult to improve their processing accuracy. At present, this type of sealing structure on the market has basically the same size. Due to machining errors, poor sealing performance or large friction torque, it can not meet the requirements of bearing use.

Solution: In order to meet the sealing requirements of bearings and the requirements of friction torque, combined with the processing accuracy and dimensional tolerance of the bearing deformable parts and the processing accuracy of the sealing ring, according to the limited bearing space, the structural size of the sealing ring is designed separately to make up for its shortcomings. The machining accuracy error of bearing parts and seals has reached the expected effect and met the requirements of users.

2. Why does the constant section sealing bearing have the problem of grease leakage?

The phenomenon is that the grease inside the bearing spills from its sealing lip.

The reason is that the bearing structure has a special size and the sealing space is small, which restricts the rationality of the sealing structure.

Solution: Choose a reasonable process method, through multiple process tests, under the premise of meeting the requirements of use, to eliminate the oil leakage of sealed bearings.

3. Why is the bearing stuck when it rotates?

The phenomenon is: when the bearing is rotating under the action of axial force or radial force, the hand feels large and small, and the operation is not smooth. Vibrations and noise may occur when spinning at high speeds or at high speeds.

The reasons are: the bearing is not clean, the working face is dirty or the working face is rough and damaged.

Solution: Select the appropriate cleaning solution and cleaning method, strictly control the quality of the working surface, improve the inspection method, and ensure that the bearing is clean without foreign matter.
