The code name of Bozheng sealed point contact ball bearing is changed from the basic code It consists of a suffixed code. The basic code indicates the bearing type, surface size and inner diameter: the suffixed code indicates the bearing seal, clearance, etc. Example: Thin-wall sealed four-point angle ball bearing FPXU1000-2RZ/C2 basic code ||tt ||FPX
