5. Servicing and Maintenance

5.3.1 Bearing Seals

It is important when replacing the labyrinth

type bearing seals in X-Press disc hubs that

the seal is fitted the right way round. The

chamfered lip side should be at the outside

of the bearing housing (see Fig. 4.06). This

chamfered lip prevents dirt ingress into the

housing and also allows grease to be flushed

though when greasing.

5.3.2 Reassembly

Simba recommend that the seal and

outermost bearing are assembled on the

spindle (as per Fig. 4.07) before inserting it

into the housing and reassembling the unit.

5.4 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.
