Fan Shaft Bearings
The fan shaft is supported by two flange mounted ball bearings, each
equipped with a lubrication fitting and a slinger/locking collar to keep
out moisture. The bearings should be lubricated as follows:
Inspection and Maintenance
• Only lubricate the bearings with a manual grease gun. Do not use
high-pressure grease guns since they may rupture the bearing seals.
• Bearings come pre-packed with Castrol EPL2 grease. BAC
recommends re-packing only with a compatible water resistant,
mineral base grease with a lithium thickener.
• Lubricate the bearings as follows:
–
Initial Start-up:
Normally, no lubrication is required since the
bearings have been lubricated at the factory prior to shipment.
However, if the cooling tower has been stored at the job site
for more than 1 year, both bearings should be lubricated
with new grease before initial operation. When lubricating,
purge the old grease from the bearing by gradually adding
grease until a bead of new grease appears at the seal on the
underside of the bearing.
–
Seasonal Start-up:
Purge both bearings with new grease prior to
start-up.
–
Operation:
Purge bearings every three months while in operation.
–
Extended Shutdown:
Purge bearings with new grease prior to any
prolonged storage or downtime.
