Each Brose motor uses 2 sprag clutch bearings. Sprag clutch bearings allow the shaft to rotate in one direction, but not the other. These bearings require lubrication to function reliably, but they also depend on friction when they are needed to stop rotation. Be sure to install the bearing in the correct orientation (check before removing the old bearing).<\/p>\n
Special grease MUST be used. If a high pressure or low viscosity grease such as ordinary bearing grease, Teflon or ceramic based greases etc. is used, the surfaces of the clutch bearing will slip under extreme load causing a high degree of wear. This can also cause the bearing to slip and seize drastically causing premature failure<\/p>\n
This is a deliberately small pack of bearing grease, but still more than enough for both bearings. This grease should be applied as a thin film to the outside of the bearing and to lubricate the inner bearing race, a thin film of grease (about 1 mm thick) should be applied to the shaft on which the bearing is mounted.<\/p>","protected":false},"excerpt":{"rendered":"
