KUKKO 21-4 Internal Puller, 2 Shells, Ø 20-30 mm

For a bearing that sits in a blind bore and cannot be reached from the outside. The two-part shell is pushed through the inner race; as you tighten the cone the shell spreads behind the race and the tool locks in. Only then can you start pulling.

Pick the size whose clamping range covers the bearing's inner diameter, no wider — a shell that is too large will not pass through. Also check the working depth: a bearing seated deep in the bore needs a longer model.

The internal puller does not pull by itself. Combine it with a counterstay bracing on the housing, or with a slide hammer that draws the bearing out using a sliding weight. Both fit the complete range, so one of each is enough alongside the seven sizes.
