Pullers

(1) Mechanical Pullers

In order to perform a proper pull, be certain that you firmly grip the gear, bearing, wheel, pulley, etc. and apply force to the shaft. Use a 3-jaw puller instead of a 2-jaw whenever possible for better gripping power and a more uniform displacement of pulling force.
The puller you select must have a reach equal or greater than the corresponding sizes of the part to be pulled. Estimate the force needed to solve your pulling problem. A puller with the proper reach and spread will usually have enough capacity to remove the corresponding part. When in doubt, always use a puller with a larger capacity than what may be needed.

(1) hydraulic Pullers

Hydraulic pullers provide an efficient means for the removal of gears, bearings, wheels, pulleys and other press fit parts. Hydraulic power provides a controlled means of applying force without the need for hammering, heating or prying.
The jaw puller can be assembled as a three-armed or two-armed puller depending on the space and demands of the application.
