Bearing Separators

Separator

with Clamping Screw

Separate bearings, collars, hubs, and other shaft-mounted items so you can remove them. After separation, use a puller (not included) to remove them from the shaft.

Separators can be used with Face-Grip Gear and Bearing Pullers. Select a face-grip gear and bearing puller with a leg thread size that matches the thread size of your separator.

Clamping Screw—Separators with a clamping screw use screw tension to force separator plates under bearings when there isn’t enough space for them to fit.

Bearing and V-Belt Pulley Separator Sets


Set with 5 Separators	Set with Face-Grip Puller	Set with Face-Grip Puller and Clamping Screw

Separate bearings, collars, hubs, and other shaft-mounted items so you can remove them. After separation, use a puller (not included with all sets) to remove them from the shaft.

5 Separators—Sets with 5 separators do not include face-grip pullers. Select a face-grip gear and bearing puller with a leg thread size that matches the thread size of your separator.

Clamping Screw—Sets that include a clamping screw use screw tension to force separator plates under bearing if there is not enough clearance.

High-Force External-Grip Gear and Bearing Puller Sets

Move the immovable—these puller sets include a hand pump and hydraulic cylinder, so you can create a large amount of pulling force. However, these pullers produce more direct, constant thrust than pullers with a forcing screw. They have mounting holes in both a 2- and 3-jaw configuration for attaching the jaws either way. The jaws have no control mechanism, so they swing free.
