Bearings made from this material are generally more expensive than chrome steel bearings. Martensitic Stainless Steel Bearings– ACD34 / KS440 / X65Cr13 Many miniature bearing manufacturers make their rings and balls with a stainless steel material with slightly lower carbon and chromium content than AISI 440C known under several names including ACD34, KS440, …

Selecting internal clearance or preload | SKF

Cylindrical, needle, spherical and CARB toroidal roller bearings typically require at least a small operational clearance. Tapered roller and angular contact ball bearings should have a small operational clearance, except in appliions where a high degree of stiffness or positional control is required, in which case they can be mounted with a degree of preload.

Bearing nuer | Basic Bearing Knowledge | Koyo Bearings …

A bearing nuer is composed of a basic nuer and a supplementary code, denoting bearing specifiions including bearing type, boundary dimensions, running accuracy, and internal clearance. Bearing nuers of standard bearings corresponding to JIS B 1512 "rolling bearing boundary dimensions" are prescribed in JIS B 1513.

A Guide to Bearing Retainers (cages) for S bearings

These standard retainers are manufactured from carbon steel for chrome bearings and AISI304 or AISI420 grade stainless steel for stainless bearings. These were often made from brass which also offered a high temperature capability but this is much less common due to higher cost of brass and advances in steel technology.
