The difference between Stainless Steel bearings and Chrome Steel bearings
Mechanical properties of stainless steel bearing materials and ordinary bearing materials. Stainless steel bearings include: 440C, 420,304, 316 and 316 material, to compare with Chrome Steel bearings, we need to put aside the rust-proof ability of the bearing, because ordinary bearings basically have no anti-rust ability, so we have to consider the mechanical properties of stainless steel bearings. From the perspective of solving corrosion problems, let’s make a basic summary of stainless steel bearings. The carbon content of stainless steel […]
Thrust Ball Bearing
Thrust ball bearing is separable in 3 parts, they are shaft washer, housing washer and steel balls with cage. Thrust ball bearings can be applied to high axial load and low medium speed, they cannot take radial load. We have both FM series (raceway with groove) and F series (raceway without groove) available for your choices. And both Chrome steel 52100(Gcr15) and stainless steel miniature thrust ball bearings are manufactured in our factories. FREE SAMPLES are available for all of […]
