(3/4" to 7/8") Kukko 21-3 Internal Bearing Extractor
For extracting inner bearings, bearing outer rings and bushings.
Description
- The 2-shell design with extra large grasp edges ensures safe extraction.
- The internal extractors are equipped with an internal safety stop to protect against excess spreading and overloading.
- Mechanical pressure screw.
Advantage
- KUKKO internal extractors can be combined with counter supports (22-1 or 22-2)) and slide hammer (22-0).
- When combined with the internal extractors, extensions from series 21-V enable deeper bearings to be extracted.
- Spare parts are available for internal extractor sizes 21-89 and 21-90.
How it works
- Place the internal extractor into the bearing's hole.
- Using a ring spanner, tighten the nuts to open the jaws of the internal extractor. Make sure that the jaws sit securely below the bearing's inner race.
- For removal, the spindle on the counter support series 22 or on the slide hammer series 22-0 is screwed onto the key spindle on the internal extractor.
- Counter support:
- 2. The counter support's arms must not block the part due to be removed. Make sure that the arms are parallel.
