What Is a Seal Puller?
A seal puller is a specialized tool for removing oil seals from the shafts and housings of mechanical products.
The seal puller makes it easy to remove an oil seal from a machine or automobile without damaging the shaft or housing.
There are two types of seal puller: one type pulls the seal by hooking the tip of the tool over the lip of the oil seal, and the other type pulls the seal by screwing in the pointy end like a wine corkscrew.
Uses of Seal Pullers
The use of seal pullers is limited to the removal of oil seals and gaskets, as these tools are specialized for this purpose.
Seal pullers are primarily used to remove oil seals, gaskets, and bearing shields.
Oil seals are used on various machine parts that are lubricated with lubricating oil or grease. Gaskets are also used to seal joints between machine parts. Bearing shields are installed to prevent dust and other debris from entering the bearings and are used in many rotating machines and other equipment.
Therefore, seal pullers are used in many situations, such as in factories and sites where maintenance and repairs are performed.
How to Select Seal Pullers
There are the following types of seal pullers, which are selected according to the application.
- Straight Type
This is the most basic type of seal puller. A T-shaped, arc-shaped head is attached to the end of the lever, and the head has sharp claws at both ends. It can be easily removed but requires sufficient working space for the lever to be folded down. - Shaft Type
This type is used when a shaft protrudes from the mounting area of an oil seal or the like. Insert the blade into the oil seal, etc., press the lever’s fulcrum against the housing, etc., and pull up the lever to remove it. The position of the fulcrum plate can be adjusted. - Screw Type
A screw-type needle is screwed into the lip of the oil seal and pulled out. This type is used when the seal is installed in a deep position or a narrow space.
