What are bearing extractors?


Designed as a tool to make bearing removal and installation simple and efficient, bearing pullers often resemble scissors. In some cases, the puller configuration will allow the pullout of gears and bearings, including those that are connected to a series of shafts within the mechanism. Different sizes of bearing pullers make it possible to use the device on everything from a pair of skates to complicated industrial machines.

Portable models of bearing pullers are usually built along scissor-like lines. The main section of the tweezers is controlled by simple inserts that allow the hand to easily open and close the mechanism. Small flat points on the end of the collets allow you to easily insert the device into a gearbox or other gear section containing the individual bearings and easily remove one or more of the small components. At the same time, pullers can also be used to put new bearings back into the mechanism, without the need to completely disassemble the entire apparatus.

Larger versions of bearing pullers are made for use in many factories. Because factories use geared equipment, the ability to replace worn out bearings quickly and efficiently is important to maintaining production quotas. Industrial size bearing pullers make this possible with little to no downtime to the production process.

In addition to working to remove and install bearings, some newer versions of the bearing puller include a small puller tool that helps serve as a guide for the collets. This addition made it possible to work with the bearings in much less time than was necessary with previous models.

Portable bearing pullers can be purchased at any hardware store. Sizes range from simple models that work well with small toys and appliances to larger versions that are ideal for working on smaller bikes and motor vehicles and household tools. More sophisticated models are available from companies that supply bearings for various types of machines.
