9.1 Mounting bearing 22320 EK/C3 on shaft no.4.
using the SKF Drive-up Method
The tightness of the it between bearing, adapter sleeve and shaft depends on how far the
bearing is pressed onto the tapered seat.
During drive-up the original radial clearance of the bearing is reduced. The preferred
method is to use the SKF Drive-up Method. Download the SKF Drive-up Method
application from skf.com. Using the Drive-up calculator select the bearing and determine
the correct starting pressure and drive-up distance for the appropriate mounting condition
(Bearing on adapter sleeve with two sliding surfaces).
Lightly oil all mating surfaces with a thin oil e.g. SKF LHMF 300 and carefully put the
bearing on the sleeve until the abutment face of the distance ring is reached. Screw the
HMV 20E hydraulic nut, with the piston facing the bearing, onto the adapter sleeve. Drive
the bearing up to the starting position by applying the HMV 20E nut pressure calculated.
Monitor the pressure by the gauge on the SKF Hydraulic Pump 729124 DU.
Then drive the bearing up the taper to the required distance from the axial drive-up
starting position. This is monitored by the SKF Dial Indicator TMCD 5P, which can be put
into the hole of the HMV E–nut. When the required distance is achieved then stop pumping
and open the pump release valve.
Return the piston of the hydraulic nut by rotating the nut clockwise on the shaft. The oil will
low back into the pump and the piston will be retracted. Remove the hydraulic nut after
mounting. Fit the locking washer and screw on the lock nut.
Note: If you have not downloaded the SKF Drive-up Method application, then the values
to be used for mounting the 22320 EK/C3 on an adapter sleeve with two sliding
surfaces are as follows:
Starting pressure
Drive-up distance

7,0 MPa (1 015 psi)
0,64 mm (0.025 in)
