3 Jaw Bearing Puller

A bearing puller is a tool used to remove bearings from a shaft or housing. Bearings are commonly used in various mechanical applications to reduce friction between moving parts. Over time, these bearings may wear out and need replacement, or repairs may require disassembly.

Here’s a general overview of how a bearing puller works:

1. Types of Bearing Pullers:
   • Two-Jaw Pullers: These pullers have two arms that grip the sides of the bearing.
   • Three-Jaw Pullers: These pullers have three arms that evenly distribute the pulling force around the bearing.
2. Selection:
   • Choose a bearing puller that is appropriate for the size and type of the bearing you are working with.
3. Usage:
   • Position the jaws of the puller around the bearing.
   • Tighten the puller’s center screw or nut to apply force evenly.
   • As you tighten the screw, the jaws will grip the bearing.
   • Continue tightening until the bearing is pulled free.
4. Considerations:
   • Ensure that the puller is aligned properly to avoid damaging the bearing or the surrounding components.
   • Apply penetrating oil if the bearing is stuck due to corrosion.
   • In some cases, heating the surrounding area with a heat gun may help loosen the bearing.
5. Safety:
   • Wear appropriate safety gear, such as gloves and safety glasses.
   • Follow the manufacturer’s instructions for the specific bearing puller you are using.
6. Alternative Methods:
   • In some situations, alternative methods like using a bearing separator or a slide hammer may be appropriate.

Always refer to the specific instructions provided by the manufacturer of the bearing puller you are using, as different models may have specific guidelines and features. Additionally, proper care and maintenance of the tools are crucial for their effectiveness and longevity.
