Bearings: Flange Bearing (Fan Shaft Related)
Bearings that are mounted within a flanged housing are used when the bearing mounting surface is
perpendicular to a shaft axis and are used for the following TCF products:
- Flange bearings available w/ Ball Type elements or Spherical Roller Type elements
- Used mostly in some Axial fans and special fan applications

Bearing Positioner
A bearing positioner is a threaded bolt mounted to a bracket on each side of the fan bearings. Used
for fine adjustments of the fan’s bearing location.

Bearing Stop Blocks
A welded bracket or key stock next to each side of the bearing welded to the pedestal. Used to
confirm bearing location.

Bearing Dowel Pins
Bearing dowel pins hold the position of the bearing to confirm proper alignment. A rod is fixed to the
pedestal for mounting through a hole on the bearings.

Bearing Vibration Sensor
Sensors are used for monitoring vibration levels at the fan bearings. The bearing housing is drilled
and tapped. Sensors are typically shipped loose for field mounting as damage could occur in transit.
Other mounting methods could include a bracket mounted through the bearing bolt or epoxy
mounting to the housing.
