| Type |
These
are two–bearing housings
where either DGBB, ACB or CRB are
fitted at each end of housing to
support an over hanging shaft,
where, on extended shaft end a
fan can be fitted thru coupling.
It is important that the seating
of two bearings at two ends are
concentric and machined accurately
in one setting. This feature is
very important for vibration-free
vibration of the assembly. The
bearing can accommodate axial load
in both directions in addition
to radial loads and are suitable
for relatively high speed operation.
The PDN & PDD housings are
supplied as assembled set consisting
of housing body, grease nipple,
covers with hexagonal screws & spring
ring / Washer, snap ring, spacer
sleeve (as the case may be), flinger
rings, seal and O ring. |
| Application |
PDN & PDD
housings support over hanging shafts
which carry the impeller of FAN.
They can also be used else where
like centrifugal pump, circular
saw and in transmission. Due to
its unique construction they as
suitable for relatively high speed
operation. Accurately machined
housing results in vibration free
operation. |
