Do you know the method of tapered roller bearing preload? - …

30/1/2019· The tapered roller bearing preload has a great influence on the running quality of the support shaft. If the pre-tightening force is small, the relative starting is relatively easy, the friction is small, but the rotation precision is not high; if the pre-tightening force is increased, the tapered roller bearing preload can be effectively improved.
