Stories of Success

Story 1:

A technician was struggling to remove a rusted bearing from a critical piece of machinery. After using a hammer and chisel for several hours without success, he resorted to a hydraulic puller. The powerful force of the puller removed the bearing in minutes, saving him hours of frustration and potential damage to the machinery.

How to:

Attach the hydraulic puller to the bearing.

Slowly increase the hydraulic pressure until the bearing pops loose.

Be sure to use a support bracket to prevent the puller from damaging the shaft or housing.

Story 2:

A maintenance team was tasked with removing a large number of bearings from a production line. To maximize efficiency, they invested in self-centering pullers. The pullers' automatic centering feature allowed the team to remove bearings quickly and accurately, saving them countless hours of alignment time.

How to:

Choose a self-centering puller that is sized appropriately for the bearings you need to remove.

Attach the puller to the bearing and tighten the jaws.

The puller will automatically center itself on the bearing, ensuring a secure grip.

Story 3:

A mechanic was replacing the bearings on a transmission. To remove the old bearings, he used a two-jaw puller. The compact design of the puller allowed him to remove the bearings from a tight space, without causing damage to the transmission housing.

How to:

Select a two-jaw puller with jaws that fit the size of the bearing you need to remove.

Attach the puller to the bearing and tighten the jaws evenly.

Use a slide hammer or wrench to pull the bearing off the shaft.

Effective Strategies, Tips, and Tricks

Choose the right bearing puller for the job based on the bearing size, type, and application.

Use a support bracket to prevent damage to the shaft or housing.

Apply penetrating oil to the bearing to loosen it before attempting to remove it.

If the bearing is particularly stubborn, consider using a hydraulic puller.

Inspect the bearing puller before each use to ensure it is in good working condition.

Common Mistakes to Avoid

Using a bearing puller that is too small or too large for the bearing.

Not aligning the puller properly with the bearing.

Overtightening the jaws of the puller.

Pulling the bearing off the shaft too quickly.

Using a pry bar or hammer to remove the bearing.
