Cylindrical Boller Bearing

For the adjustment of the tightness of the front wheel bearings of the Nissan TKL-20 car, it is necessary to first tighten the adjustment nut to a torque of 400 Nm. Then, after turning the wheel 2-3 times, loosen the nut by 1/6-1/4 turn. At the beginning of the operation, measure the tension of the wheel using a spring scale and adjust it to 55 Nm. For certain car models, it is not only required to tighten the adjusting nut and locking nut with specific torque, but also to tighten and loosen the adjusting nut multiple times, with different tightening torques and loosening turns each time.
