Inch Ball Bearings ect
Bearing material
High carbon chrome beating steel(Gcr15)is the standard material for bearing rings&rolling elements,following is its chemical composition.Also carbon steel&stainless steel will be used upon request.

CAGES
In general,JYL cages are pressed steel ribbon cages&pressed steel snap cages.For extra-high speed application,synthetic-resin,stainless steel,nylons will be used upon request.
----------------------------------------------------------------------------------------------------------------------------------------
SEALS&SHIELDS
SPCC are mainly used for JYL shields,also catbon steel&stainless steel can be used.Buna Nitrile is standard sealing material we use, while fluorocabon, silicone, and teflon seals are commonly specified for high temperatures.

Vibration And Noise
The vibration and noise of bearing are classified in four classes as Z1,Z2,Z3 and Z4.It is measured by the instrument of SO910-1.For special requirement,it is measured by BVT-1 and classified as V1,V2 and V3.The data are shown in below tables.Different vibration&noise requirement should be mentioned in order.
