Lubrication
FAN SHAFT BEARINGS
The fan shaft is supported by two pillow block ball bearings (see figure below), each equipped with a lubrication
fitting and a flinger/locking collar to keep out moisture.
Under normal operating conditions the bearings should be greased every 1000 operating hours or at least every
three months. The bearings should be lubricated with one of the following water resistant inhibited greases, which
are good for ambient temperature ranging from - 20°C to 120 °C.

Extended lubrication line
The bearings should be lubricated only with a hand grease gun. Do not use high-pressure grease guns, since they
may rupture the bearing seals. When lubricating, purge the old grease from the bearing by gradually adding grease
until a bead of new grease appears at the seal. In particular when extended lubrication lines are fitted ensure that
all old grease is removed and that new grease is leaving the seal.
If bearings are replaced, grease must be added to the new bearings after installation. Make sure new bearings are
fully greased (spare bearings may not be fully filled with grease).
For grease products see table below.
