Pullers

Pullers are for loosening compounds by using a screw or hydraulic press.

How does a puller work?

Pullers are tools for loosening component compounds which can’t be loosened by hand because they hold into position by their own friction force. With the aid of a screw or a hydraulic press the necessary force is applied to seperate the components. Depth and width can be adjusted variably.

What models are available?

There are different types of pullers. For inside or outside use, separators and bearing puller. Three-armed pullers are mostly preferred to two-arm pullers because of providing more secure grip when pulling. Two-armed pullers are used in situations where space is limited. These tools are used, for example, in mechanical engineering.

 

Which puller for which job?

The job

Removing a gear, bearing, pulley, or other Component from a shaft

Tools to use

  • Jaw type puller. Two or three jaw style, with three jaw being the best choice. Manual or hydraulic with outside jaw positions.
  • Push/Pull puller. Use male or female adaptors to thread into tapped holes on components.
  • Slide hammer puller. Use on light duty applications. For use with attachments.
  • Bar type puller with bearing separator. Bar type with side rods threaded into bearing separator provides "knife edge" to get behind component or when there is not a good gripping edge.

 

The job

Pulling a shaft out of a housing or bare

Tools to use

  • Push/Pull puller. Use male or female adaptors.
  • Bar type puller with bearing separator. Use when housing lacks sufficient surface for puller side rods to bear against.
  • Slide hammer puller. Use on light duty applications. For use with attachments.
  • Slide hammer puller. Use with male or female adapters.

 

The job

Removing a bearing or bushing from a blind hole.

Tools to use

  • Jaw type puller. For inside jaw positions (inside pulls), a manual oder hydraulic jaw type puller can be used with pressure screw or slide hammer variations. 
  • Expanded collet puller. Pulling can be done with bridge, bar type yokes or slide hammers.
  • Bearing adaptors with slide hammer puller. Bearing adapters with slide hammer should be used in this application.
  • Bar type puller with bearing separator. Bar type with side rods threaded into bearing separator provides "knife edge" to get behind component or when there is not a good gripping edge.
