Suitable for larger bearings
Provides a more even pull

Three-jaw pullers are great for larger and tougher bearings. They are more stable but can be more challenging to set up. Ensure all three jaws are evenly spaced for the best results.

Internal Bearing Pullers

Internal bearing pullers are used for bearings inside a housing or casing. They grip the inner race of the bearing. The tool expands inside the bearing to hold it securely.

Ideal for bearings in tight spaces
Grips the inner race of the bearing
Useful for blind holes

Internal bearing pullers are specialized tools. They are perfect for removing bearings from hard-to-reach places. These pullers can be more complex to use but are very effective for their specific purpose.

Safety Precautions

Removing The Bearing

Removing a bearing from a shaft can be tricky. But with the right tools, it becomes easier. A puller is one of the best tools for this job. Let’s go through the process step by step.

Positioning The Puller

First, position the puller over the bearing. Make sure it is centered. The arms of the puller should grip the bearing firmly. Check that it won’t slip during use.

Applying Force Evenly

Next, apply force evenly. Turn the puller’s screw slowly. This will create a steady pull. Do not rush this step. Slow and steady wins this race.

Checking For Bearing Movement

As you apply force, check for bearing movement. The bearing should start to move along the shaft. If it does not, stop and reposition the puller. Then try again.

Dealing With Stubborn Bearings

Dealing with Stubborn Bearings can be a real challenge. Bearings can sometimes get stuck and refuse to budge. This can be frustrating, especially when you need to get the job done quickly. Below are some effective methods to help you deal with those stubborn bearings.

Using Penetrating Oil

Penetrating oil is a great helper. It seeps into tight spaces and loosens rust and grime.

Spray the oil directly onto the bearing.
Let it sit for a few minutes to work its way in.
Try using the puller again after the oil has had time to work.

This method can make a big difference. Penetrating oil can save you time and effort.

Applying Heat

Heat can help expand the metal, making it easier to remove the bearing.

Use a heat gun or a propane torch.
Apply heat evenly around the bearing for about 2-3 minutes.
