  • Patent number: 4852235
    Abstract: A bearing puller comprising an elongated body member having a plurality of gripping arms at one end thereof with gripping shoulders being provided at the free end of each of the gripping arms. An elongated bolt is threadably mounted in the body member and has one end positioned between the gripping arms. A sleeve is longitudinally slidably mounted on the bolt and is designed to deflect the gripping arms outwardly when moved into a first position and to prevent inward deflection of the gripping arms during the bearing removal process. An actuator slidably embraces the body member and is operatively connected to the sleeve to enable the sleeve means to be selectively positoned. In a modified form of the invention, the bolt member is not utilized but is replaced by a slide hammer operatively attached to the body member.
