Roller bearing faults

Damage to roller bearings can be difficult to detect in some cases. If in doubt, replace the

bearing. Use other bearing designs only after consulting the manufacturer.

Table 8-3

Roller bearing faults

↓ Bearing overheats

↓ Bearing "whistles"

↓ Bearing "knocks"

Possible causes of faults

Remedial measures

High coupling pressure

Align the machine more accurately.

Belt tension too high

Reduce the drive belt tension.

Bearing contaminated

Clean or replace the bearing. Check the seals.

High ambient temperature

Use a suitable high-temperature grease.

Insufficient lubrication

Grease the bearings as instructed.

Bearing canted

Contact the Service Center.

Insufficient bearing play

Contact the Service Center.

X Excessive bearing play

Contact the Service Center.

Bearing corroded

Replace the bearing. Check the seals.

Too much grease in bearing

Remove surplus grease.

Wrong grease in the bearing

Use the correct grease.

X Friction marks on raceway

Replace the bearing.

X Brinelling or scoring

Replace the bearing. Avoid any vibration at standstill

8.9.5

Cooling system faults

The following table shows the possible causes of and remedial measures for faults on water-

cooled machines.

Table 8-4

Cooling system faults

↓ Overheating

↓ Water leaking

Possible causes of faults

Remedial measures

Reduced cooling

● Check the cooling water flow, increase the amount of cooling water

if necessary.

● Clean the cooling system, e.g. by briefly increasing the cooling

water flow rate or by adding suitable cleaning agents.

Cooling water flow rate too low

Consult the manufacturer. If the specified cooling water quality is ob‐

served, the cooling system is maintenance-free.

Inlet temperature too high

Set the correct upstream temperature.

Cooling water supply switched off

Switch on the cooling water supply.

Cooling water contains too many or unsuit‐

able antifreeze and corrosion-protection

agents

Use cooling water of the agreed quality.
