Hand pump
Operation
The mounting operation begins with mounting of the rolling bearing
on the tapered seat,
Figure 5
. Slide the rolling bearing gently onto
the shaft or slide the mounting sleeve into the original position.
A suitable hydraulic nut is then screwed onto the shaft and the hand
pump is connected. The hand pump is then operated until
the pressure to reach the start position is achieved. The hand pump
is now operated (number of strokes in accordance with the table)
until the rolling bearing has been driven up the required
displacement distance and the end position is achieved.
The pressure is then released and the hydraulic oil flows back into
the pump, after which the pump can be removed.
Note
In order to avoid delays during mounting, we recommend that
the initial pressure and the number of strokes is determined before
the start of mounting.
Mounting the rolling bearing
Slide the rolling bearing gently onto the shaft. In this way,
it is possible to avoid sliding the rolling bearing on further than
the start position.
If the rolling bearing is slid on further than the start position,
the radial clearance is too small.
Mounting the hydraulic nut
Locate the hydraulic nut on the tapered shaft or withdrawal sleeve.
Screw a coupling nipple into the hydraulic nut.
