Thrust ball bearing is a common type of bearing, which is mainly composed of three parts: seat ring, shaft ring and steel ball retainer assembly. It must be recognized when choosing thrust ball bearing,Wuxi Spark Bearing Co.,Ltd tell everyone about the material analysis of thrust ball bearing, can let you further understand the thrust ball bearing, master the knowledge of thrust ball bearing, choose and buy more safe.

Thrust ball bearings are generally mainly used in the material is steel, but not all steel is suitable, this mechanical hardware accessories are generally used in the bearing steel, because this will be more ideal.

Bearing steel has a high and uniform hardness and wear resistance, as well as a high elastic limit.Bearing steel has strict requirements on the uniformity of chemical composition, the content and distribution of non-metallic inclusions, and the distribution of carbides. It is one of the most stringent steel types in all steel production and is often used as a material for thrust ball bearings.Need WSBC 21318 E,click here to learn more.

Thrust ball bearing is a separable bearing, the shaft ring and seat ring can be separated from the assembly of cage and ball.The shaft ring is a ring matched with the shaft, the seat ring is a ring matched with the bearing seat hole, and there is a gap between the shaft;Thrust ball bearing can only bear axial load, one-way thrust ball bearing can only bear axial load in one direction, bidirectional thrust ball bearing can bear axial load in two directions;Thrust ball bearings cannot limit the radial displacement of the shaft, and the limit speed is very low. One-way thrust ball bearings can limit the axial displacement in one direction of the shaft and the housing, and two-way bearings can limit the axial displacement in both directions.

Thrust roller bearings are used to bear combined axial and radial loads mainly, but the radial load shall not exceed 55% of the axial load.Compared with other thrust roller bearings, this kind of bearing has lower friction factor, higher speed and better centering performance.Click here to learn more about WSBC 22208 E.

Thrust ball bearing features:

1, with one-way, two-way type;

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

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

4. High grease technology -- The 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. the use of the optional ring, can allow the installation error.

In order to meet the performance requirements of dynamic bearings, the following basic performance requirements are proposed for bearing steel materials:

(1) High contact fatigue strength,

(2) After heat treatment, the bearing should have a high hardness or the hardness that can meet the performance requirements of the bearing.

(3) High wear resistance, low friction coefficient,

(4) High elastic limit,

(5) Good impact toughness and fracture toughness,

(6) Good dimensional stability,

(7) Good anti-rust performance,

(8) Good cold and hot working performance.

Bearing steel can also be used in the manufacture of precision measuring tools, cold punching dies, machine tool screws, such as stamping dies, measuring tools, taps and diesel engine oil pumps.Bearing steel is the steel used to make ball bearings, rollers and bearing rings
