Slide Hammer Pullers: The Power Tool That Packs a Punch for Removing Stuck Parts

What Is a Slide Hammer Puller?

A slide hammer puller is a specialized tool used for removing objects that are tightly fitted or stuck in place. It consists of three main components: a weight (hammer), a shaft, and a set of jaws or pulling attachments. The basic mechanism involves using the weight’s inertia to apply a sudden, forceful pull on the object being removed.

The weight, typically made of heavy metal like steel, slides along the shaft. When the weight is slid back and then allowed to slide forward, it builds up momentum, creating a powerful pulling force. The jaws or pulling attachments are designed to securely grip the object being removed, transferring the force from the sliding weight.

Slide hammer pullers are effective for dislodging bearings, bushings, gears, and other tightly fitted components from shafts, housings, or bores. The sudden impact created by the sliding weight helps overcome the friction or corrosion that may be holding the object in place, making it easier to remove without damaging the surrounding components.
