The main material used for thrust ball bearings is steel, but not all steels are suitable. This kind of mechanical hardware is generally used for bearing steel, because this kind of comparison is ideal.
Bearing steels have high and uniform hardness and wear resistance, as well as high elastic limits. The uniformity of chemical composition of bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict. It is one of the most demanding steel grades in all steel production, and is also commonly used in thrust ball bearings. A material.
The thrust ball bearing is a separate type of bearing, and the shaft ring and the seat ring can be separated from the components of the cage and the steel ball. The shaft ring is a ferrule that cooperates with the shaft. The seat ring is a ferrule that cooperates with the bearing housing hole, and there is a gap between the shaft; the thrust ball bearing can only bear the axial load, and the one-way thrust ball bearing can only bear Axial load in one direction, two-way thrust ball bearings can withstand axial loads in two directions; thrust ball bearings can not limit the radial displacement of the shaft, the limit speed is very low, one-way thrust ball bearings can limit one of the shaft and the housing Axial displacement of the direction, the two-way bearing can limit the axial displacement in both directions. Thrust roller bearings are used to support axial and radial combined loads with axial loads, but radial loads must not exceed 55% of axial loads. Compared with other thrust roller bearings, this type of bearing has a low friction factor, high speed and self-aligning performance.
Thrust ball bearing features:
1. Available in one-way and two-way types;
2, in order to allow installation errors, whether it is one-way or two-way, you can choose spherical spherical spherical seat cushion type or spherical seat type;
3, high-quality steel – the use of ultra-clean steel that can extend the life of bearings up to 80%;
4, high grease technology ― NSK lubricant technology can extend the life of grease and improve the performance of bearings;
5, high-grade steel ball ― quiet and smooth when rotating at high speed;
6. Use the ferrule in the option to allow for installation errors.
