Since their introduction, the Crozier bushing and bearing extractors (pullers) have solved the
problem of extracting inexpensive bushings and bearings from very expensive machine tools and
parts. Now those expensive machine tools and parts can be saved and reused over and over again.
Crozier bushing and bearing extractors uses includes aircraft and aircraft components, automotive
related parts such as alternator housings and pilot bushings, and delicate instrument bearings
used on high technology medical equipment. Around the world, major airlines, military bases,
engine rebuilding facilities, and many others are using this simple, powerful and durable set of
tools. The Crozier bushing and bearing extractors can remove bushings, bearings and many other
objects from blind holes. If your application calls for a bushing or bearing removal, chances
are we have the tool for you.
The use of the Crozier Bushing and Bearing Extractors not only result in large savings in the
time required to perform the task, but remove the hazard of damage to the machine tool or part.
The bushing and bearing extractors are available in two sizes. Select from the menu to the left
for details.
Extractor Applications
Shown is the method of extracting a sleeve, or friction bearing, such as pilot bearings on
flywheels. This approach is used when it is not possible to reach under the sleeve, and when the
gripping shoulders of the extractor can bury themselves in the metal.
Illustrated is the romoval of a hardened valve insert. The sharp edges of the extractor wedge
themselves between the insert and the block, allowing the insert to be removed.
Roller bearing cups, races of magneto type ball bearings, and similar shapes are quickly and
easily removed as shown. Expanding the arbor causes the shoulders to grip under the edge of the
bearing race. This is easily accomplished, even when there is only a slight radius on the lower
edge of the race.
To remove ball bearings from a blind hole, insert a small size extractor through the hole in the
bearing. Expand the extractor with the shoulders of the extractor under the bearing. Use only a
small amount of force to remove the bearing.
