5. Servicing and Maintenance
5.5 Double Disc Axles
The axles on this roller are tensioned by the
main axle through the centre of the rings and
bearings.
Specialist equipment is required
for the disassembly of Double Disc
axles. Please consult your dealer
under any circumstances that
require disassembly of these
axles.
Maintenance of these rollers is limited to daily
greasing of the bearings to flush out dirt, and
regular inspection to ensure the assemblies
are tight, and scrapers are correctly set. The
axles can be tightened provided the bearing
pillar ‘U’ bolts are loosened to avoid
preloading the bearings as they move
sideways to each other. Ensure the bearing
pillars are re- tightened to the mainframe after
this.
5.3.2 Bearing Seals
It is important when replacing the labyrinth
type bearing seals in disc hubs that the seal
is fitted the right way round. The chamfered
lip side should be at the outside of the bearing
housing, nearest the disc arm (see Fig. 5.02).
This chamfered lip prevents dirt ingress into
the housing and also allows grease to be
flushed though when greasing.
