Bearing or Glass Sink|Bathroom Sink|Faucet Technical Reference
1. Characteristics of Various of Glass Sink|Bathroom Sink|Faucet
2. Material
-The rings, balls, needles and rollers of WD Glass Sink|Bathroom Sink|Faucet 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|Bathroom Sink|Faucet) skeleton
The chemical composition of bearing steel and stainless steel are listed as follows:
Steel No. c% Si% Mn% S% P% Cr%
