What is the working principle of bearing puller?
what's the working principle of bearing puller,functions of bearing puller
Every bearing puller falls into the broad categories of either an external bearing puller and an internal bearing puller.
External bearing pullers are used when the bearing is mounted onto a shaft. They have jaws which grip the outer diameter of the bearing, along with a forcing screw which pushes against the end of the shaft. As the forcing screw is tightened, the jaws force the bearing along the shaft.
An Hydraulic bearing puller set
This type of puller can be either mechanical or hydraulically-assisted. A Hydraulic Bearing Puller requires minimal manual effort, making them ideal for heavy-duty applications. However, specialist heavy-duty bearing pullers are also available for these applications.
Internal or blind bearing pullers are used where the bearing or component is fitted within a recess, with an opening in the inner diameter. The puller is inserted into the inner diameter of the bearing where it grips the bearing. This can be through expansion or using claws. The bearing can then be pulled from the recess.
Reversible bearing pullers are also available. This type of pullers is suitable for both internal and external pulling, thanks to their reversible arms. This makes them ideal for use in applications where there are bearings fitted both on shafts and in recesses.
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.
A reversible bearing puller being used to remove a deep groove ball bearing from the end of a shaft. 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.
