Bearing must be repacked after approximately
10,000 hours of operation. For proper bearing
lubrication fill the bearing cavity with grease for
approximately 1/3 of its cavity.
Non-brake motors bearings are packed with:
Mobilux EP2 Grease.
Brakemotor bearings are packed with: Texaco
Premium RB Grease.
SEVERE DUTY MOTORS
Severe duty motors have double sealed (2RS)
bearings on the fan side end.
Severe duty motors have drain holes drilled in
the stator end shields at the lowest points to
allow condensation to drain out of the motor.
The same applies to the conduit box.
CAUTION:
THE
DRAIN
HOLES
ARE
INSTALLED FOR THE MOUNTING POSITION
LISTED ON THE NAMEPLATE. CHANGING
THE MOUNTING POSITION WILL ALSO
RELOCATE THE DRAIN HOLES IN WHICH
CASE WATER MAY NOT BE ABLE TO
DRAIN OFF AND PREMATURE MOTOR
FAILURE
MAY
OCCUR.
