Product Details
Bearing show: Precision Deep Groove Ball Bearings(EMQ Bearings) 693ZZ 3*8*4mm
Material:
RINGS & BALLS vacuum degassed, high carbon chromium bearing
steel GCr15 is the standard material for precision bearing rings
and balls. The material has uniform specification as AISL
52100(America)DIN100 Cr6(German), JISSUJ2(Japan)
These deep-groove ball bearings are suited to parts of devices that
require high-speed rotation, low-friction torque and low
vibration/noise in order to make such devices smaller,
lighter-weight and thinner.
