The benefits are stronger, quieter, more efficient and longer life. Bearing plates have more advantages in the factory. The bearings are delivered pre-installed in the bearing plate, which means that only one part needs to be pressed onto the shaft and tightened normally. During assembly, the plate can rotate freely on the bearing, but the orientation between the two plates can be fixed by the lock design, or the guide notch in the gearbox housing can be used to prevent the plate from rotating.
