Orion Motor Tech blind-hole collet bearing & seal puller kit, 16‑pc with slide hammer

The Orion Motor Tech 16-piece blind hole collet bearing race and seal puller kit is a heavy-duty slide hammer and collet extractor set designed to remove blind bearings, races, seals, and bushings from 6–59 mm (1/4–2-1/3 in) bores with controlled, non-destructive force.

This complete blind-bearing removal kit gives mechanics and DIYers a reliable alternative to destructive chisels or press setups. Built from forged AISI 1045 carbon steel with chromoly collets and housed in a custom blow-molded case, the kit combines a slide hammer, counterstay puller, multiple threaded adapters and ten split collets to fit a wide range of internal-diameter parts. It’s made to help extract parts from tight, obscured bores where external pulling faces aren’t available.

How does the kit remove blind bearings without damaging nearby components?

The kit uses expanding split collets that lock inside the inner race or bore of the part, then transfers extraction force axially with a slide hammer or a controlled counterstay tightening method. This inward gripping and axial pull minimizes contact with adjacent surfaces and reduces scoring or deformation.

• Ten split collets cover 6–59 mm internal diameters for a snug grip.
• Slide hammer delivers quick, concentrated impact pulls where needed.
• Counterstay lets you tighten and withdraw parts gently for delicate work.
• Threaded adapters ensure collets and tooling align with varied part geometries.

What tools are included and what sizes will it handle?

The set contains a slide hammer, a counterstay puller, a spare pin bolt, three screw adapters, and ten split collets that expand to fit internal diameters from roughly 1/4 inch up to 2-1/3 inches (6–59 mm). Together the pieces handle most wheel bearing races, seals, and bushings found on cars, light trucks, and small machinery.

• Slide hammer for forceful extraction of stubborn parts.
• Counterstay for controlled, gradual removal.
• Three screw adapters to match different threaded ports or bores.
• Collets sized to span the 6–59 mm range for internal grips.

Is this kit durable enough for repeated shop use?

Yes — components are forged from AISI 1045 medium carbon steel and the collets use chromoly for enhanced toughness. The primary parts are galvanized to resist corrosion and maintain reliable thread engagement and fit after repeated use.

• Forged AISI 1045 steel body resists bending and impact fatigue.
• Chromoly collets withstand repeated expansion and high grip loads.
• Galvanized finish reduces rust for lasting performance.
• Blow-molded case protects tools and keeps sizes organized.

How simple is it to use for non-professional mechanics?

Basic operation is straightforward: select the collet that best matches the internal diameter, seat it in the bearing’s inner race, lock it in place, then use the slide hammer for rapid removal or tighten the counterstay for careful extraction. The included adapters and spare pin keep the kit adaptable for slightly different part geometries.

• Pick a collet, insert and expand to seat inside the part.
• Attach slide hammer for decisive pulls or counterstay for controlled draws.
• Use screw adapters to match irregular bores or threaded interfaces.
• Store everything in the custom blow-molded case between jobs.

Who is this for? This Orion Motor Tech blind hole collet puller kit suits professional technicians, home mechanics, and restoration hobbyists who need a compact, durable extractor for internal bearings, seals, and bushings. It’s particularly useful when parts sit flush or recessed in housings and can’t be gripped externally — ideal for wheel bearing races, axle bushings, gear housings, and many small-engine or transmission applications. The kit reduces the need to cut or destroy parts during removal and keeps work organized with a protective case.
