HQSSWUCH 21-in-1 Bearing Puller Set — Blue Case, Three-Jaw Internal Puller with Heat-Treated Red-Steel Collets

This multi-piece set combines a three-jaw inner-hole puller, six precision collets, curved hooks, heavy red-steel components and a sturdy carry case to tackle a wide range of bearing sizes. Designed for professional maintenance and DIY repairs, the tools are heat-treated for strength and finished for corrosion resistance so they hold up under repeated use.

How does this kit remove inner bearings without harming parts?

The three-jaw design centers inside the bearing inner ring while the collet grips distribute force evenly, which reduces stress on housings and shafts. Turning the main threaded rod extracts the bearing straight out, avoiding prying or hammering that can distort parts.

• Three-jaw puller engages the inner ring evenly for balanced extraction.
• Six sized collets fit a broad range of inner diameters to prevent slippage.
• Heat-treated red-steel components resist bending under load.
• Threaded rod accepts standard wrenches for controlled force application.

Which sizes and models will this set work with?

The kit covers many common industrial and automotive bearing references by supplying multiple collet sizes plus additional hooks for non-standard parts. Check the included sizing list to confirm compatibility with your bearing codes before starting a job.

• Includes collets compatible with 6005–6310 series bearings and similar inner diameters.
• Three curved hooks allow extraction of bearings, gears, and pressed-on components.
• Set works for both small machine bearings and medium automotive hubs.
• Precision slots in the case help match the right collet quickly on the workbench.

What makes this kit durable and easy to store?

Every load-bearing part is drop-forged and heat-treated for high hardness, while the three-jaw puller receives a black-oxide finish to resist corrosion. The molded plastic carrying case holds each piece in a dedicated pocket to prevent loss and to extend tool life between uses.

• Rugged drop-forged construction for long-term strength under repeated use.
• Black oxide and red-steel finishes slow rusting and simplify cleanup.
• Custom foam or molded slots keep parts organized and protected during transport.
• Lightweight case handle makes carrying to job sites convenient.

How should I use and maintain the puller for best results?

Choose the collet that matches the inner ring size, seat it between the inner and outer rings, then tighten the top rod with a wrench while maintaining alignment. Lubricate the threaded rod before use to reduce friction and preserve the tool’s threads for smoother operations.

• Select the closest-fitting collet to avoid slippage and uneven force.
• Apply light machine oil to the threaded rod before each use.
• Keep the puller centered and turn the rod steadily to extract parts straight out.
• Store components in the case to prevent rust and lost pieces.

Who is this for: technicians, mechanics, and serious DIYers who frequently service motors, gearboxes, wheel hubs and industrial assemblies will find this HQSSWUCH set especially useful. It’s designed for users who need a reliable, transportable solution for removing internal bearings and pressed-on parts without resorting to destructive methods. If you work with a variety of bearing sizes and value organized storage and durable construction, this 21-in-1 set gives a practical balance of range, strength and portability.
