The rolling bearing is a unique mechanical detail that adjustments the sliding friction among the running shaft and the shaft seat into rolling resistance, thereby decreasing friction losses. Rolling bearings are normally composed of 4 elements: an internal ring, an outer ring, a rolling body and a cage. The function of the internal circle is to cooperate with the shaft and rotate with the shaft; the part of the outer ring is to paintings with the bearing seat to assist the position; the rolling frame is assisted by using due to the fact the cage flippantly distributes the rolling elements among the internal and outer rings, its shape and quantity without delay affect the overall performance and lifestyles of the rolling bearing; the cage can evenly distribute the rolling factors, prevent the rolling factors from falling off, and manual the rolling factors. Rotate for lubrication.

I. Rolling bearing characteristics


in the processing of bearing components, a large range of specialized system for bearings are used. Such as steel ball processing using ball mills, grinders and other stuff. The characteristics of specialization are also contemplated in the manufacturing of bearing parts, including metallic ball groups that specialize in the manufacturing of metallic balls, and miniature bearing factories that specialize in the manufacturing of miniature bearings.


because of the big-scale requirements of bearing manufacturing, it's far viable to use advanced machine gear, gear and techniques. Such as CNC machine equipment, 3-jaw floating chucks and protective ecosystem warmness remedy.


The specialization of bearing manufacturing gives the situations for production automation. A big quantity of fully automated, semi-automated devoted and non-dedicated gadget tools are used in production, and automatic manufacturing traces are gradually promoted and applied. Such as heat remedy computerized line and meeting automated line.

category of rolling bearings

Rolling bearings may be divided into deep groove ball bearings, needle roller bearings, angular contact bearings, spherical ball bearings, round roller bearings, thrust ball bearings, thrust spherical roller bearings, cylindrical curler bearings, tapered rollers Bearings, round ball bearings with seats, and so on.

1.Deep groove ball bearings

Deep groove ball bearings have a simple shape and are easy to apply. They're the sort of bearings with the maximum widespread manufacturing volume and the most extensive software variety. It's far specially used to endure radial load and also can take a certain axial load. When the radial clearance of the bearing is improved, it has the feature of an angular contact bearing and might bear a big axial load. utilized in motors, tractors, gadget tools, automobiles, pumps, agricultural equipment, textile machinery, and so on.

2. Needle roller bearings

Needle curler bearings are equipped with skinny and lengthy rollers (the duration of the rollers is three to ten instances the diameter, and the width is commonly now not more than 5 mm). Consequently, the radial structure is compact. The smallest diameter, especially appropriate for help systems with restrained radial set up dimensions.

3.Angular contact bearings

Angular contact ball bearings have a higher restriction pace and might help both meridional and axial loads, in addition to natural axial hundreds. The axial load ability is determined by using the touch perspective and will increase with the touch attitude. Ordinarily used: oil pumps, air compressors, various transmissions, gasoline injection pumps, printing equipment.

4. Self-aligning ball bearings

Self-aligning ball bearings have two rows of metallic balls, and the inner ring has raceways. The outer ring raceways have an inner spherical shape and have automated self-aligning overall performance. It could automatically catch up on the coaxiality blunders due to the bending of the shaft, and the deformation of the housing and is appropriate for elements where the guide seat hollow cannot assure strict coaxiality.

5. spherical roller bearings

round roller bearing sentences have two rows of rollers, which can be specifically used to take radial hundreds and can also deliver axial loads in any direction. This form of bearing has excessive radial load capacity, specifically suitable for working below heavy load or vibration load, but can't bear natural axial load; it has first-rate self-aligning overall performance and may compensate the identical bearing mistakes.
