Rolling-contact bearing faults

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

bearing. Contact the Service Center.

Table 8-3

Roller bearing faults

↓ Bearing overheats

↓ Bearing "whistles"

↓ Bearing "knocks"

Possible causes of fault

Remedial measures

High coupling pressure

Align the machine more accurately.

Ambient temperature higher than 40 °C

Use high-temperature grease.

Insufficient lubrication

Grease the bearings as instructed.

Too much grease in bearing

Remove surplus grease. Contact the Service Center, if necessary.

Wrong grease in the bearing

Use the correct grease.

Belt tension too high *

Reduce the drive belt tension.

Bearing contaminated

Contact the Service Center.

Bearing canted

Insufficient bearing play

Bearing corroded

X Friction marks on raceway

X Brinelling or scoring

X Excessive bearing play

X Mechanical wear of bearing elements
