INTRODUCTION
REPLACEMENT OF ROLLER BEARINGS
These bearings are usually made up of two parts:
• Outer ring (or cup)
(1) .
• "bearing cone" assembly
(2) , consisting of the inner
track with the rollers (cylindrical or conical) and the
cage.
Thus, the removal and installation of tapered bearings is
carried out in two parts: the cup and cone.

To remove tapered bearing cups
• Normally, the cups are only removed in case of replace-
ment.
• In this case, use pullers (if available) and then, blow the
cup off the housing by means of a pin puller.
• In the latter case, removal can be destructive. However,
take care not to damage the housing.

To remove bearing cones
Whenever possible, use universal pullers, of two or three
legs

To install tapered bearing cups and cones
• For the cups
(1) ), use tools that fit the inner face (track)
or behind the cup, on the longest side.
• To install the bearing cones
(2) on axes, use a press
(preferred) or a hammer combined with a suitable tool.
• Never apply hammer blows directly on any parts of a
bearing!
• Also, check the alignment of the installation, done on a
flat, hard and perpendicular surface.
