LEGEND Metric miniature bearings
d = Inner diameter in mm
D = Outer diameter in mm
B = Bearing width in mm
B1= Width for ZZ or 2RS executions
D = Outer diameter in mm
B = Bearing width in mm
B1= Width for ZZ or 2RS executions
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). Load ratings of stainless steel bearings are approximately 70% of chromium steel bearings. The maximum speed limit of 2RS bearings is approximately 50% of open or ZZ executions.
