You would typically use a KUKKO series 22 counter-support or a series 22-0 slide hammer. Always check the thread size compatibility before purchase.</p> <strong>Can this extractor be used for removing sealed bearings?</strong><br><p>Yes, it can be used for sealed bearings. The jaws are designed to grip the inner race of the bearing, behind the balls. For sealed bearings, you might need to first remove the seal on one side to get a proper grip.</p> <strong>What is the correct procedure for using the 21-7 internal extractor to avoid damaging the bearing or housing?</strong><br><p>Insert the extractor into the bearing’s inner ring. Tighten the spindle to expand the jaws and ensure a firm, even grip. Attach the counter-support or slide hammer. Apply force axially and straight, without tilting, to pull the bearing out smoothly.</p> <p>Last Update: Friday, March 13, 2026</p> <p><em>profideals is not an authorized distributor, reseller or representative of the products featured on this website.
