A puller is a tool that is widely used to remove different parts like gears, bearings, or pulleys from a machine shaft. Removing the shaft-mounted components will not be easy if you are not choosing the right kind of hydraulic puller. Adding to this, the dirt, corrosion, and interference fits make the removal process even more difficult. So it is essential to know about the type of pullers and their uses to get your hands on the right type.
If you are curious to learn about the different types of pullers available, read this article to get an idea about the pullers types and their uses.
There are different types of pullers present. If you choose the right type of puller, you can expect it to do the work safely, efficiently without causing any damage to your machinery. Now without any adieu, let’s move on to the types.
Two Jaws and Three Jaw Pullers
These are the most common types of pullers based on jaws. The three-jaw pullers consist of an extra arm that helps in distributing the force equally. Though it is large and occupies much room, this type of pulley is widely used. While the two jaw bearing puller also does a decent job, it is less efficient than three-jaw pullers, provided it must be handled with care.
Mechanical and Hydraulic Pullers
These types of pullers act as great tools for removing components in various industrial sectors.
Mechanical pullers operate by rotating a crossbar which in turn moves the center bolt towards the shaft. It requires some manual work.
The hydraulic pullers are equipped with a hydraulic cylinder powered by a pump to apply the required force to operate. The plunger provides direct and non-twisting application of thrust that is more effective and secure than other types.
The 2 jaw and 3 jaw pullers are available for both mechanical and hydraulic puller types.
Internal Pullers
The internal pullers come with an attached slide hammer that allows a high-impact force to be applied to the workpiece. This type of puller is mostly used to remove shaft-mounted parts with no spindle support.
Why is the Advantage of Using Pullers Over its Alternatives?
You might want to try alternatives to pullers like cutting, torching, hammering, but these processes come with potential risks, and immense safety measures must be taken to do them. Besides, they tend to damage your machine over time. This is why puller tools are most preferred to do this type of job.
Application of Different Types of Pullers
Below we have listed out some examples of pullers applications in various industries.
Shipbuilding – Equipment and engine maintenance
Oil and gas – Frac pump coupler pulling
Aerospace – Helps in pulling propellers and rotors
Power generation – Dismounting generator bearings
Mining – Pulling, removing pins.
Conclusion
That’s a wrap now. These are the main types of pullers present. Irrespective of the type, small types of pullers are used by technicians in small automotive workshops, whereas larger tonnage models are used in heavy industries.
