Inside Bearing Pullers: A Comprehensive Guide to Choosing and Using the Right Tool

An inside bearing puller is a specialized tool designed to remove bearings from shafts and other components. It consists of a series of arms or legs that are placed behind the bearing, and a screw or hydraulic mechanism that applies force to the arms to pull the bearing off the shaft.

Types of Inside Bearing Pullers

There are two main types of inside bearing pullers:

• Mechanical inside bearing pullers use a screw mechanism to apply force to the arms. They are relatively inexpensive and easy to use, but they can only generate a limited amount of force. According to the American Bearing Manufacturers Association, inside bearing pullers are ideal for smaller tasks, such as removing bearings from bicycle wheels.
• Hydraulic inside bearing pullers use a hydraulic cylinder to apply force to the arms. They are more powerful than mechanical inside bearing pullers, but they are also more expensive and difficult to use. They come with an attachment that allows the user to choose the pulling force required.

Choosing the Right Inside Bearing Puller

When choosing an inside bearing puller, it is important to consider the following factors:

• The size of the bearing you need to remove.
• The amount of force required to remove the bearing.
• The type of shaft the bearing is mounted on.
• The space available around the bearing.

Using an Inside Bearing Puller

Once you have chosen the right inside bearing puller, you can follow these steps to remove the bearing:

1. Clean the area around the bearing.
2. Place the arms of the inside bearing puller behind the bearing.
   3 Adjust the arms so that they are evenly spaced around the bearing.
3. Tighten the screw or hydraulic mechanism to apply force to the arms.
4. Continue tightening the screw or hydraulic mechanism until the bearing is removed from the shaft.

Safety Precautions

When using an inside bearing puller, it is important to take the following safety precautions:

• Wear safety glasses and gloves.
• Do not exceed the maximum force capacity of the inside bearing puller.
• Be careful not to damage the shaft or other components when removing the bearing.
• If you are not sure how to use an inside bearing puller, consult a qualified mechanic.

Maintenance

To keep your inside bearing puller in good working condition, it is important to perform the following maintenance tasks:

• Clean the inside bearing puller after each use.
• Lubricate the screw or hydraulic mechanism regularly.
• Inspect the inside bearing puller for damage before each use.

Costs

The cost of an inside bearing puller varies depending on the type, size, and features. Mechanical inside bearing pullers typically cost between $20 and $100, while hydraulic inside bearing pullers can cost between $100 and $500.
