To receive the radial direction load primarily, and can withstand a small amount of axial load bearing, it can take it under load minus the radial load, how much can handle after load, called residual load. As bearing, can bear load for 300 kilograms, is now the radial direction load 200 kg, and the rest of the load for 100 kilograms, this 100 kg called residual load.
According to the characteristics of bearing design cant bear all axial load, so also took a coefficient K, the coefficient is called residual load coefficient.
For example: have a NSK 305 bearing, allow for 1100 kg load, now had the radial load 800 kilograms, so the NSK bearings can handle many axial load?
After check the maintenance manual "know the table to the heart NSK bearing single ball of the load factor K = 0.70, this NSK bearing axial load for PP = K (Q a R) = 0.7 x 1100 = 210 (kg).
