There are several types of pullers that are used to remove components like bearings from rotating shafts. Common types include hand-powered pullers with a screw mechanism, hydraulically powered pullers, bearing splitter plates that use a pushing mechanism, 2-arm and 3-arm pullers with reversible claws that get behind bearings, internal pullers with a slide hammer mechanism, and bar-type pullers that use a threaded rod and separator. The main components of pullers are the hexagonal head, forcing screw, cross arms, and reversible claw legs. Pullers come in various sizes to accommodate different bearing diameters.

DIFFERENT TYPES OF PULLERS
What is Puller?
Types of Puller :- A puller is a tool used to remove sets from the rotating machine shaft. The
most common application of puller is removing a caped set of ball or tapered bearing from a
rotating shaft. For example In car transmission pullers are made up of steel of tool grade. While
tool grade is harder than the parts they are used on.
Type of Puller
Generally these pullers are hand powered with a handle to turn the screw. Some are powered
hydraulically using hydraulic power piston to press against the end of shaft the bearing is on.
These pullers are also comes within small variety in sizes to remove the (mm) size bearing. These
are arms with extension that gives slight edge to user for pulling bearing easily during the
operation.

Main components of puller
Some main parts of the pullers assembly are listed below:
1. Hexagonal head on bearing puller – hexagonal head is attached to the
forcing screw. It is fixed with socket wrench for rotation with ease.
2. Bearing puller forcing screw – forcing screw is long & fine threaded
screw that is rotated corresponding to the shaft. When they force is applied
to the screw to produce force that is transmitting to the components that we
are removing.
3. Bearing pullers cross arms – the cross arms attaches the legs to forcing
screw.
4. Reversible claw legs on a bearing pullers – legs allows internal &
external pulls.
Types of Puller
These pullers include bearing splitter plates, 2 and 3 arms bearing pullers, internal bearing
pullers, bar type puller &slide hammer puller.
1. Bearing Splitter Plates
Bearing splitter plates are safest types of bearing pullers to use. From technically point of view
they are actually not puller as they uses the mechanism of pushers, they tends to push and pop (
meet or fixed) with the shaft.

Bearing splitter plates
Bearing splitters plates mainly consist of two plates held together with respective to their large
diameter, heavy nut with good duty screwed with the help of nut on the all 4 ends.

These are one of the most common types of pullers to extract (removal) of bearing sets or gears.
Arms having fingers on the end that bend to get behind the bearing. The center screw of the puller
is torqued so it pushes on to the top of shaft & upward thrust is applied to the bearing. Arms and
fingers are reversible so same puller can accommodate the wide variety of bearing & shaft sizes,
length.
3. Internal Bearing Puller
Internal bearing puller
Internal bearing pullers are made up to extract bearing set. These are generally favorable in
condition of small dent puller. They have a slide hammer with shaft to act thrust upward &shock
to the bearing. Collet is the part that went into the bearing at the tip of puller shaft is expandable.

4. Bar type Puller with Bearing Separator
Bar type with side rod threaded into bearing separator provides knife edge to get behind
components or when there is not good gripping edge at all.
