Features :
To bear predominate radial load and subsidiary axial load from both directions, lower cost and price, low running resistance, high limiting speed, possible to reach higher rotating precision and pretty low vibration level, in addition, possible to make into sealing structure.
Bearing material
Outer ring, inner ring, ball:
High-carbon chromium bearing steel Gcr15(JIS SUJ2,AISI 521000), or stainless steel 9Cr18(AISI 440C)
Cages:
Steel plates and nylon can be used in general situation, while rubber and stainless steel for special usage.
Cover:
Steel plate for shield, and rubber for seals
Rings and balls vacuum dealing with treatment of high carbon chromium bearing steel GCR15 is the standard material to produce the accurate internal and external circle and ball. This material is same with the USA AISL 52100, Germany DIN 100Cr6, Japan JISSUJ2.
The standard cage is made of carbon steel by cold, but in-corrosive environment, no parallel, or under high-speed operation, we can use stainless steel, nylon or phenolic resin cage according to customer’s request.
