RINGS & BALLS
Gcr15 high carbon chromium bearing steel is the standard material
for precision bearing rings and balls. The chemical composition
of the material is shown on the table one. The contrast of Bearing
Steel No. of each country see table two. |

RETAINERS
The retainers is normally adopt H62 copper sheet of 08F cold
rolled steel belt. However, in cases of corrosive environment,
misalignment, or high speed operation. Stainless steel, nylons,
or phenolic resins will be used upon request. |
SHIELDS & SEALES
The shields also employ steel as standard and the option AISI-300
stainless available when needed. We use a variety of sealing
materials to meet the requirements of high temperature operation
and compatibility with greases. Buna Nitryl is the standard
material used, while fluorocarbon, silicone, and Teflon seals
are commonly specified for high temperature. |
