Different Types of Bearing Pullers and How to Choose the Right One

Published: 15 Jul 2025

Bearing pullers are very useful tools in mechanical work. They help you remove bearings safely without damaging the shaft or nearby parts. These tools are used in many places, like car workshops, heavy machinery repair, and construction sites. If you’re fixing anything that rotates, chances are you’ll need a bearing puller. Let’s explore what they are, how they work, and which type is best for your job.

What is a Bearing Puller?

A bearing puller is a tool used to pull bearings out from machines, engines, or shafts. Instead of using force like a hammer, this tool applies even pressure to gently remove the bearing. This keeps your parts safe and saves time during repairs.

Types of Bearing Pullers

Bearing pullers come in different shapes and styles. Each is made for a specific task. Let’s take a look at the most common types you’ll find in workshops and garages.

Internal Bearing Puller

Internal bearing pullers are designed to fit inside a bearing and pull it out from within. It goes into the center of the bearing and grips it from the inside. Then, it pulls the bearing outwards. Internal pullers are ideal when the bearing can’t be accessed from the outside.

3 Jaw Bearing Puller

This is one of the most popular types. It has three arms that grip the outer side of the bearing. It pulls the bearing out by turning a center screw. Because of the three arms, the pulling force is spread evenly, which makes it safe and stable to use.

2 Leg Bearing Puller

This puller works like the 3-jaw version, but has two arms. It’s useful in small or tight spaces where a 3-jaw puller does not fit. It needs more care to keep it balanced while pulling.

Hydraulic Bearing Puller

This tool uses hydraulic force instead of manual turning. It’s perfect for heavy-duty tasks. With less effort, it delivers strong pulling power. Mechanics often use hydraulic pullers for industrial or automotive jobs where bearings are very tight.

External Bearing Puller

This type grips the outside of the bearing. Use it when the bearing is exposed and not hidden. It’s a simple and common puller, often seen in everyday repair work.

Reversible Bearing Pullers

Reversible pullers can work both internally and externally. You can flip the jaws to suit the task. These are flexible and a smart choice if you want one tool for many jobs. They’re handy for mechanics who need to switch between tasks quickly.

Pilot Bearing Puller

Pilot bearing pullers are made for small bearings in tight places, like inside engine crankshafts. They expand inside the bearing and then pull it out smoothly. Mechanics often use these when repairing clutches or engines.

How to Choose the Right Bearing Puller Tool

The right puller depends on the task.

Bearing Position

Know where the bearing is located, whether it’s inside a housing, on a shaft, or deep within a machine.

Bearing Size

Check the size of the bearing, including its diameter and its depth. The puller should match these dimensions.

Work Space

Look at the space around the bearing. Tight areas may need smaller or more compact tools, while open spaces offer more flexibility.

Force Required

Some bearings come out easily, while others are stuck tight. Choose a puller based on how much pulling force you’ll need.

Tool Strength and Quality

Always use strong, well-made tools. They last longer, work better, and reduce the risk of damage.

Flexibility & Attachments

Some jobs may require extra parts like claws, extensions, or impact tools. Make sure your puller setup can adapt.

Conclusion

Bearing pullers make tough jobs simple. Whether it’s a small pilot bearing or a big industrial one, there’s a tool that fits. By understanding the types of bearing pullers, you can pick the right one and work faster with less damage. Got a job waiting? Choose wisely and let the right puller do the hard work for you!

FAQs

What is the best type of bearing puller?

It depends on the job. The best puller matches the bearing’s size, location, and how tight it is.

How to select a bearing puller?

Look at the bearing’s position, size, workspace, and force needed. Choose a puller that fits these needs.

What is a 3-jaw puller used for?

It removes bearings or gears by holding them firmly on the outside. It’s great for balanced, safe removal.

What is an alternative to a bearing puller?

You can use heat, a hammer, or a press, but these can damage parts. A puller is the safer option.

Do bearing pullers damage bearings?

Not if used correctly. Pullers are made to remove bearings safely without harm.
