UNIOR Pullers: Two-Jaw and Three-Jaw, Internal Bearing Pullers, and Car Pullers for Hubs, Ball Joints and Wiper Arms
, by عامر شوب, 2 min reading time
How to choose the right puller: two-jaw or three-jaw, size by the diameter of the part, internal bearing pullers, and specialised UNIOR car pullers.
A puller removes bearings, pulleys and gears from a shaft without hammering and damaging them. UNIOR is one of the best-known names in pullers, because the jaws are forged and do not spread under pressure.
Two-jaw or three-jaw?
- Two-jaw: fits into tight spaces, suitable when there is only room for two arms.
- Three-jaw: spreads the force over 3 points, so the pull is steadier and the part does not tilt. Best for bearings and pulleys.
| Puller | Size |
|---|---|
| Two-jaw | 130-250 mm |
| Large two-jaw | 300-400 mm |
| Two-jaw | 90-350 mm |
| Small two-jaw | 90×90 mm |
| Three-jaw | 130-250 mm |
| Small three-jaw | 90×90 mm |
How to choose the size? Measure the diameter of the part you want to pull and the distance from its edge to the shaft, and choose a puller whose maximum size is slightly larger.
Internal bearing pullers
If the bearing is inside a housing (not on a shaft), you need a puller that goes inside it and expands:
- 6-piece set 6.5-36 mm.
- 3-piece set 40-60 mm.
- Internal puller head 6.5-50 mm sold individually.
To hold the part while you work: puller stand 240×430×200 mm.

Usage tips
- Place the jaws on the furthest solid point of the part, not on thin edges.
- Tighten the centre bolt with a wrench gradually, and do not use an air impact gun on a standard puller.
- Spray rust remover on the shaft before pulling.
- Wear safety glasses, because the part can come off suddenly.
Pros ✅
- Forged jaws that withstand high pulling force
- Special pullers for every part of the car
Cons ❌
- You must choose the right size; a small puller on a large part can break
