TIANAOKEJI Internal Bearing Puller Slide Hammer Kit — Double-Headed, 300mm Alloy-Steel for Pilot Bearings & Bushings

TIANAOKEJI Internal Bearing Puller Double Headed Slide Hammer Puller is a double-headed, alloy-steel internal slide-hammer kit for removing pilot bearings, bushings and internal sleeves from motorcycles and cars.

Compact and built for workshop and DIY use, this TIANAOKEJI tool combines two interchangeable collet heads with a 300 mm slide hammer shaft so you can extract internal bearings without dismantling housings. Its alloy-steel construction and simple clamp-switching design let you grip inner rings securely and deliver controlled impact to dislodge stuck parts. The kit includes the collets, hammer, shaft, screw and an allen key so you have a ready-to-use internal pulling solution wherever clearance is limited.

How does the double-headed design make bearing removal easier?

The two clamp heads cover overlapping size ranges so you can select the right collet for a snug internal grip. Switching heads is quick: thread the collet into the shaft, lock it with the provided screw, then expand the collet inside the bearing and use the slide hammer to extract. The double-headed approach reduces the need for multiple one-size tools and speeds up repeat jobs.

• Small head working range: 16–35 mm for smaller pilot bearings and bushings
• Large head working range: 26–50 mm for larger internal sleeves
• Interchangeable collets for a better, non-slip internal grip
• One kit covers a wide range of common vehicle internal pulls

What makes the slide hammer and shaft reliable for stubborn bearings?

The slide hammer and shaft are engineered to transfer impact energy in a straight, controlled path so you avoid twisting or damaging the housing. A 300 mm (1.2 ft) length gives enough travel to develop extraction force while the alloy-steel components resist bending and wear. The handle provides a steady grip so impacts feel predictable and manageable even in confined spaces.

• Slide hammer length: 300 mm for efficient impact range
• Alloy-steel shaft and hammer resist deformation under repeated use
• Handle design improves control and reduces slippage during pulls
• Threaded connection enables firm fastening of collets to the shaft

Which internal pull applications is this tool best suited for?

This puller is intended for internal pulls where a traditional external yoke cannot engage, such as pilot bearings, internal sleeves, and bushings within hubs or engine components. It is especially useful when you must extract a component without removing adjacent parts or when access is limited. Use only where the collet can expand and seat firmly inside the inner ring or bore.

• Pilot bearing removals in transmissions and flywheels
• Internal sleeves and bushings inside hubs or housings
• Applications with limited external access or confined clearance
• Workshop and roadside repair situations requiring compact tooling

Who is this tool for? Mechanics, home-garage enthusiasts and mobile technicians who regularly tackle engine or drivetrain maintenance will find the TIANAOKEJI Internal Bearing Puller especially useful. It’s suited to anyone needing a compact internal extraction kit that covers a broad size range (16–50 mm) and delivers reliable slide-hammer force without investing in multiple specialty extractors. Avoid using it on brittle castings or severely corroded parts without first assessing risk of housing damage.
