Bearing Height: bearing diameter from the shaft, the shaft is determined, so by loading conditions, load bearing by bearing a high pressure P (N/mm²) of the decision,
usually bearing the L/D (bearing height/bearing diameter), the ratio in the range of 0.5-3 for the appropriate,
but should pay particular attention to the high load, easy cause deviation contacts, high-speed situations caused by heat, then L/D is more appropriate to take the following 1.
Bearing wall: plain bearings with rolling bearings compared to the wall thickness less restricted, thin wall thickness of one of its main advantages.
Under normal circumstances, the wall thickness t= (0.05~0.07) d= (2~5) mm.
