Since the numberof rolling elements is notstandardised, different grippersmay be required for the samebearing sizes from differentmanufacturers. The bearingmanufacturer must be specifiedwhen ordering.• For tight fit of inner ring or outer ring.• For cases in which the inner ringis adjacent to a shaft shoulderwithout extraction slots, and alsowhere the bearing to be extractedfrom the shaft is still inside ahousing.• Extraction without damage ispossible with proper handling.• Max. shaft diameter 75 mm.lLL + ExtensionOperation and handlingThe special extractor consists of abasic unit and a gripper, which isscrewed onto the upper section ofthe basic unit. The gripper is closedusing the left hand thread of theunion nut and clamped against theinner ring with a conical clampingring. A threaded spindle generatesthe extraction force.The finger-shaped extensions of thegripper engage between the rollingelements on the raceway edge ofthe inner ring, behind the rollers orbehind the chamfer of the bearingring, wedging it loose. The extractionprinciple must be observed whenselecting the suitable gripper forthe respective bearing, see page 25.ØDProduct range - special bearing extractors 64ØdOrdering designationBasic unit forDimensions SpindlethreadMassWspecial extractor d D l LmmkgPULLER64-400 30,5 60 78 135 M14~1,5 1,25PULLER64-500 46 75 80 150 M20~2 2,5PULLER64-600 66 100 92 170 M22~2 3,8PULLER64-700 77 126 120 205 M30~2 7,8The basic unit is selected such that the dimension d is greater than thebearing bore, for example PULLER64-700 (d = 77 mm) for rolling bearing 6015with 75 mm bore.24
