Some bearing manufacturers now offer databases and computer programs to determine bearing frequencies. Another fact that assists in recognizing fundamental bearing frequencies is that they almost occur at non-integer multiples of operating speed (non-synchronous) such as 4.3 x rpm, 5.6 x rpm, 6.8 x rpm, etc.

1/10/2020· Contact angle in TRBs is the angle made by the contact line between roller and raceway with bearing axis. In TRBs, the inner race and outer race contacts make different angles with bearing axis. They are related as, (1) α o = α i + 2 β where α o is the outer raceway contact angle, α i is the inner raceway contact angle and β is the semi-taper angle of the tapered roller.
