Performance requirements of seamless steel pipes for bearings

by suli lee on Mar 9, 2022 Business 66 Views

Bearing seamless steel pipe is also called high carbon chromium seamless steel pipe, the carbon content WC is about 1%, and the chromium content WCr is 0.5%-1.65%. Bearing seamless steel pipe is further divided into high carbon chromium bearing seamless steel pipe, chromium-free bearing seamless steel pipe, carburized bearing seamless steel pipe, stainless steel bearing seamless steel pipe, medium and high temperature bearing seamless steel pipe and anti-magnetic bearing seamless steel pipe. kind.

High-carbon chromium bearing seamless steel pipe GCr15 is the largest bearing seamless steel pipe in the world. The carbon content of WC is about 1%, and the chromium content of WCr is about 1.5%. Since its birth in 1901 to the present for more than 100 years, the main components are basically no Change, with the progress of science and technology, research work continues, product quality continues to improve, accounting for more than 80% of the world's total production of bearing seamless steel pipe. So that if there is no special description for the bearing seamless steel pipe, it refers to GCr15.

Bearing seamless steel pipe is the steel used to make balls, rollers and bearing rings. Bearing seamless steel pipe has high and uniform hardness and wear resistance, as well as high elastic limit. The requirements for the uniformity of chemical composition, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict, and it is one of the most stringent steel types in all steel production.

In order to meet the above requirements for the performance of the movable bearing, the following basic performance requirements are put forward for the bearing seamless steel pipe material:
1) High contact fatigue strength;
2) After heat treatment, it should have high hardness or hardness that can meet the performance requirements of the bearing;
3) High wear resistance and 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 processing properties.
