Mounting Bearing 22320 Ek/C3 On Shaft No. 1 Using The Clearance Reduction (Traditional) Method - SKF TMDS 6 Bedienungsanleitung

few times to allow the rollers to assume their correct positions. The clearance is measured,
using a feeler gauge, between the outer ring and the uppermost rollers.
After determination of the radial clearance (values of clearances and clearance reductions
can be found in the SKF Rolling Bearing Catalogue), the spherical roller bearing is pushed
manually far as possible upon the shaft seat. Screw the hydraulic nut on the shaft, with the
piston facing the bearing, until the piston is touching the bearing inner ring.
Pump oil into the hydraulic nut with pump 729124 DU until the bearing is pressed
far enough on the tapered journal. This is the case when the required reduction of the
clearance is obtained.
Since the bearing is positioned on the shaft, the clearance is now measured between the
lowest rollers and the outer ring. When the required clearance reduction 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 and it the locking washer and
screw on the lock nut. Finally, check again the clearance of the bearing.

The SKF Drive-up Method is the preferred
method for mounting tapered bore SKF
Spherical roller bearings on tapered shafts.
However the traditional clearance reduction
method can be used for non SKF bearings
and for instances where insuficient tools
are present. During drive up the original
radial clearance of the bearing is reduced.
To check the it obtained this reduction of
clearance is measured. Therefore, the radial
clearance of the unmounted spherical roller
bearing must be determined. Place the
bearing upright and rotate the inner ring a
