MANNIFEN 6-Inch 2-Jaw Gear Puller — Compact Reversible Bearing & Pulley Removal Tool, CR-V Steel

Compact, reversible 2-jaw gear puller designed to remove small bearings, pulleys and gears without harming parts. The MANNIFEN 6-inch 2-jaw gear puller is a compact removal tool built for mechanics and hobbyists who need controlled, reliable extraction of bearings, pulleys, and gears from shafts and housings. Constructed from heat-treated CR-V alloy steel, this puller combines durability with a reversible jaw layout so it can work internally or externally in confined spaces. Its moderate size and clear specifications make it especially useful where larger pullers are impractical.

How does this puller handle both internal and external removal jobs?

The puller’s arms are reversible so you can flip them to grab the outside of a flange or expand inward to engage an inner race. Switching modes is straightforward: remove the bracket, rotate the jaws, and reassemble—no special tools needed. The reversible design is ideal for alternately extracting bearings from housings and pulling off pulleys from shafts.

• Reversible jaws for internal or external grip
• Bracket with anti-drop pins secures jaws during operation
• Screw drive provides steady, controllable pulling force
