Product Details
The Kukko internal extractors are designed for the extraction of inner bearings, bearing outer rings, and bushings, and can be effectively combined with counter supports and slide hammers. For deeper bearing extractions, extensions from series 21-V can be utilized alongside the internal extractors. This kit includes spare parts specifically for internal extractor sizes 21-89 and 21-90. The extractors feature a robust 2-shell design with extra-large grasp edges to ensure safe extraction and are equipped with an internal safety stop that protects against excess spreading and overloading. They utilize a mechanical pressure screw, with a strict warning against the use of electrical or pneumatic servo screwdrivers or hammer drills. Proper safety precautions include the mandatory use of protective blankets and goggles. The internal extractor has a length of 73mm, is compatible with ball bearings ISO 625, 635, 626, 607, 627, 608, 619/8, and 628/8, accommodates inner diameters of ball bearings ranging from 5 to 8mm, and has an effective depth of 14mm.
