Product Details
The Kukko internal extractors are designed for extracting inner bearings, bearing outer rings, and bushings. The kit includes internal extractors that can be combined with counter supports and slide hammers, with extensions from series 21-V allowing for the extraction of deeper bearings. Spare parts are available for internal extractor sizes 21-89 and 21-90. The extractors feature a 2-shell design with extra large grasp edges for secure extraction and include an internal safety stop to protect against excess spreading and overloading. The mechanical pressure screw is specified for use, and it is crucial to avoid using any electrical or pneumatic servo screwdrivers or hammer drills, with protective blankets and goggles required during operation. The length of the internal extractor is 89 mm, and it is compatible with ball bearings ISO 6004, 6204, 6304, 6404, 6804, 6904, 16004, 61804, and 61904. The inner diameter of the ball bearings ranges from 18 mm to 23 mm, with an effective depth of 35 mm.
