Service Condition
1
Motors must be specially designed for operation in ambient outside the range of –30 to 40 degrees C
(–22 to 104 degrees F). Special grease is required.
2
"Extreme" service conditions are rare in actual practice. Corresponding lubrication cycles should therefore
be applied with caution. It is also advisable to check with Allen-Bradley for related special instructions.
Table I
Relubrication Periods – Frames C210ATZ - C440ATZ
1
Maximum speed occupying more than 30% of operating time.
2
For Tandem drives increase frequency of lubrication by multiplying values by 0.8.
Frames C210ATZ - C440ATZ
These motors are designed to route new grease directly into the
bearing. The relubrication periods shown in
are offered as a
guide for varying service conditions, speeds, bearing types and
operating hours.
Important: Certain special motors may have a lubrication instruction
plate permanently attached. These specific lubricating
instruction must be followed.
Lubrication Procedure
1. Relubrication with the shaft stationary and a warm motor is
recommended.
2. Locate the grease inlet at the top of the bearing hub, clean the
area and replace the 1/8 inch pipe plug with a grease fitting (if the
motor is not equipped with a grease fitting).
