Material Analysis of Thrust Ball Bearings

Thrust ball bearing is a common type of bearing. It is mainly composed of three parts: seat ring, shaft ring and steel ball cage assembly. When purchasing thrust ball bearings, you must look for it. According to the understanding of China Bearing Network, Telling you about the material analysis of thrust ball bearings will enable you to further understand thrust ball bearings, master the knowledge of thrust ball bearings, and make purchases safer.

Thrust ball bearings generally use steel as the main material, but not all steels are suitable. This kind of mechanical hardware accessories are generally made of bearing steel, because this is more ideal.

Bearing steel has high and uniform hardness and wear resistance, as well as a high elastic limit. The uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict. It is one of the most stringent steel types in all steel production, and it is also commonly used in thrust ball bearings. a material.Thrust ball bearing is a separable bearing, the shaft ring and seat ring can be separated from the cage and steel ball assembly. The shaft ring is a ring matching the shaft, and the seat ring is a ring matching the bearing seat hole, and there is a gap between the shaft and the shaft; thrust ball bearings can only bear axial loads, and one-way thrust ball bearings can only bear axial loads. For the axial load in one direction, the two-way thrust ball bearing can bear the axial load in two directions; the thrust ball bearing cannot limit the radial displacement of the shaft, and the limit speed is very low, and the one-way thrust ball bearing can limit one of the shaft and the housing Axial displacement in one direction, two-way bearings can limit axial displacement in two directions. Thrust roller bearings are used to bear axial and radial combined loads dominated by axial loads, but the radial load must not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has a lower friction coefficient, higher speed and self-aligning performance.

Features of thrust ball bearings:

1. There are two types of one-way and two-way;

2. In order to allow installation errors, whether it is one-way or two-way, you can choose the spherical self-aligning spherical seat cushion type or the spherical seat ring type;

3. High-quality steel - use ultra-clean steel that can extend the life of the bearing by up to 80%;

4. Advanced grease technology - NSK's lubricant technology can prolong the life of grease and improve the performance of bearings;

5. High-grade steel ball - quiet and smooth when rotating at high speed;

6. Using the ferrule in the option, installation errors can be tolerated.
