Notes:
The tables above are specifically intended
for relubrification with MOBIL Polyrex EM
grease and bearing absolute operating
temperature of:
 70ºC (158ºF) for 160 to 200 frame size
motors
 85ºC (185ºF) for 225 to 355 frame size
motors
For every 15ºC (59ºF) above these limits,
relubrification intervals must be reduced by
half. Shielded bearing (ZZ) are lubricated for
bearing life as long are they operate under
normal conditions and temperature of 70ºC
(158ºF).
 Relubrication periods given above are for
those cases applying MOBIL Polyrex ® EM
grease.
 When motors are used on the vertical
position, their relubrication intervals are
reduced by half if compared to horizontal
position motors.
 On applications with high or low
temperatures, speed variation etc., the type
