TIANAOKEJI Internal Bearing Puller — Double‑Head Slide Hammer 300mm, Expandable Collets 16–50mm

TIANAOKEJI Internal Bearing Puller Double Headed Slide Hammer is a two-head expandable collet slide-hammer kit for removing internal bearings and sleeves quickly and with minimal effort.

This compact internal puller set is built for workshop and roadside use on motorcycles, cars, and light machinery. It uses two interchangeable collet heads and a 300mm (1.2 ft) slide hammer shaft to lock inside a bearing's inner race, then extracts the part by impact rather than prying. Made from alloy steel, the components resist wear and let you switch clamp sizes to match a wide range of internal diameters.

How does this tool remove internal bearings without damaging surrounding parts?

The puller expands inside the bearing inner ring to create a secure grip, so force is applied centrally instead of from the outside. Pulling is accomplished by sliding the hammer weight along the shaft to deliver controlled impact, which separates the bearing or sleeve without levering against delicate housings.

• Expandable collets lock inside the inner race for centered extraction
• Slide hammer delivers controlled axial blows instead of prying force
• Two clamp head sizes cover small to mid-range internal diameters
• Alloy-steel construction reduces slippage and component deformation

Which bearing sizes and vehicles will this double-headed puller work on?

The kit covers most pilot bearings, internal sleeves, and bushings encountered on motorcycles, passenger cars, and small industrial equipment. With two clamp heads you can match the collet to the inner diameter before expanding and extracting.

• Small head working range: 16–35 mm for tight, compact bearings
• Large head working range: 26–50 mm for larger sleeves and bearings
• 300 mm (1.2 ft) slide hammer length for strong, controllable pulls
• Suitable for pilot bearings, internal sleeves, and similar internal pulls

What is included in the package and how do I assemble it?

The kit ships with everything needed to set up and operate the puller right away. Assembly is straightforward: thread the chosen expandable collet onto the shaft, tighten the screw to hold it, then use the slide hammer and handle to extract the part after expanding the collet inside the inner race.

• 1 x expandable collet (double-head design for two size ranges)
• 1 x slide hammer shaft with handle for axial pulling
• 1 x slide hammer weight to generate impact force
• 1 x screw and 1 x Allen key for tightening and assembly

How do I use the slide hammer safely and get best results?

Use steady, controlled strikes on the slide weight and avoid excessive, uncontrolled force to protect housings and shafts. Make sure the collet is fully locked inside the bearing inner ring and that the workpiece is supported or clamped to prevent movement during extraction.

• Confirm correct collet size and secure expansion inside inner race
• Support the housing to counteract axial force during pulling
• Deliver measured slide-hammer blows rather than sudden extreme impacts
• Inspect threads and fasteners before each use for safe operation

Who is this for: TIANAOKEJI's double-headed internal puller suits mechanics, DIY enthusiasts, and small repair shops that need a reliable tool for removing internal bearings, pilot bearings, and sleeves without specialized press equipment. It’s ideal when access is limited, or when a compact, durable slide-hammer solution is preferable to disassembly or costly replacement.
