Ball Bearing Extractor 56

Application

• For extracting complete radial ball bearings
• For ball bearings with a tightly fitted outer ring
• For bearings that are radially not accessible
• As the extraction hooks are applied at the outer ring and the threaded spindle is applied at the shaft, the extraction force is transmitted via the rolling elements, rendering the bearing unserviceable.

Operation

The extractor claws grasp the raceway edge of the outer ring between the balls and are supported by the inner ring. The bearing is extracted by means of a threaded spindle.

Depending on the bearing size, one of three extractor sizes and one of 13 sets of claws (see table on page 9) is selected. The number of arms required, and their arrangement, depends on the number of balls in the bearing.

Complete extractor sets consist of one extractor, three or five sets of claws and a wrench with T-shaped handle in a box, see table below.
