How to decide what type of puller to use

The decision of which puller to use is dependent on many factors. You’ll first need to establish whether you need an external or an internal bearing puller.

If the component that you’re removing is seated on a shaft and is freely accessibly from the outer diameter, you’ll need an external bearing puller. This is the most common type of puller. However, if the part you’re trying to remove is in a recess with the inner diameter accessible, you’ll need an internal bearing puller.

If you require an external bearing puller, you’ll then be able to choose between mechanical and hydraulic bearing pullers. If you’re on a tight budget, a mechanical bearing puller may be suitable. However, if you’re working with heavy-duty machinery, you might consider a hydraulically-assisted bearing puller to reduce the manual effort required.

You’ll also need to consider the space conditions. This includes the diameter and depth of the bearing, along with the available space around the bearing. Some bearing pullers will require more space to operate than others.

The choice of which bearing puller to use should always be made after careful consideration of all influencing factors. If you’re unsure which bearing puller to choose, it’s best to consult an expert before making your decision.
