1-2. Amount of grease

Generally, grease should be supplied into the housing such that one third or half of the internal space is filled, though the grease amount should be adjusted according to the housing construction and the size of internal space. When the grease amount is excessive, it may be heated up by agitation and changing the properties of deteriorating or softening, grease. If the bearing is used at a low speed, the space may be filled up to two thirds or entirely to prevent ingress of foreign matter.
