H B C Bearings - Bearing Noise


HBC Bearings are manufactured in V2 and V3 grades, tolerances of ABEC 3/P6. Please refer to our Vibration Speed Level below for anderonmeter readings on the Low/Medium/High bands.


VIBRATION SPEED LEVEL (A)

ROTATION SPEED: 1800R/min

N=2.5

ANDERONMETER uin/rad


















Each HBC Bearing shall be tested at two random locations on the stationary outer ring with thrust applied to the other outer ring in the direction in which the bearing can accept operational thrust load. Vibration level reading at each of the two locations shall be taken in Table.


All readings shall be averaged.
