  • Bearing protector
    Patent number: 4659240
    Abstract: A bearing protector attached to a shaft abuts against the inner race of a bearing mounted to a housing. The body of the protector extends over substantially all of the outer race. The protector does not contact the outer race due to a running clearance. Side loads which would otherwise contact the bearing seals are held by the protector which is secured to and rotates with the shaft.
