Three-Arm Extractor 53

Application

• For extracting complete rolling bearings or tightly fitted inner rings as well as similar parts
• Good radial and axial accessibility of the bearing location, possibly slots, required

Operation

Depending on bearing size and mounting conditions, the extractor with the suitable dimensions is selected. The span can be adjusted by turning the knurled disk above the upper star. The two stars move on the cylinder symmetrically to each other so that the entire spread range can be covered with just a few rotations. The arms are locked during the extraction process so that they cannot be opened accidentally.

Rolling bearing rings that are extracted correctly do not get damaged. Complete bearings where the extraction force is transmitted through the rolling elements usually become unserviceable.

The availability of hydraulically assisted larger extractors (suffix H) will be indicated on inquiry.
