Checking friction torque of tapered roller bearings

The bearings must be greased and without ring seal

1

Rest the pinion gear on the press plate, apply the specified force on it, and spin the hub several times in both directions.
. 



2

Wind a rope around the pinion gear housing with a dynamometer fastened to the end of the rope.



3

Confirm the force specified for the press and pull the dynamometer horizontally and, disregarding the initial pull, observe the value indicated on the dynamometer scale.

If there is not a press

Checking friction torque of tapered roller bearings

Alternative method

4

Assemble the flange of the gear pinion fork without the ring seal, and tighten the nut with the specified tightening torque.
. 



5

Hold the assembly in a bench vice and measure the friction torque of the bearings with a spring dynamometer.
