LEGEND  Double row angular contact bearings

d = Inner diameter in mm
D = Outer diameter in mm
B = Bearing width in mm

Cr (N) = Dynamic load rating in Newton (N)
Cor (N) = Static load rating in Newton (N)

N = kg * 9.8 
kg = N / 9.8

rpm = maximum rounds / minute * 1000

Bearings listed here are also available with Z-shields (Z, ZZ) or RS-seal (RS, 2RS). The maximum speed limit of 2RS bearings is approximately 50% of open or ZZ executions.
