1. Characteristics of
Various of glass sink
2. Material
-The rings, balls, needles and rollers of WD glass sink can be made
of refining bearing steel AISI52100, stainless steel AISI440C, AISI420,
etc.
-Cages are normally punch-pressed from brass strips H62 or steel
strips 08, SPCC BQB402, as well as stainless steel strips AISI304,
AISI302, fiber reinforced phenolic resin, plastics or copper stock,
etc;
-The shields can be made of Japanese SPCC JISG3141 or stainless
steel AISI304 or AISI302.
-Seals: synthetic rubber hot pressed with phosphatizing steel (AISI304
or AISI302 may used for stainless steel glass sink) skeleton

sink)
Precision of taper roller glass sink
Precision of thrust ball glass sink
Precision of conic bore radial glass sink
5. Deep Groove Ball Bearing£s Vibration and Noise Class
The vibration and noise of deep groove ball glass sink are normally
classified as Z1, Z2(higher class than Z1), and Z3 (highest class).
It is usually measured by instrument of SO910-1. While for glass
sink used for electric motors, the vibration & noise is measured
by BVT-1 and classified as EMQ ZV1, ZV2 and ZV3. Customer needs
to mark the requirement of vibration and noise class in order.
