Lubrication - Allen-Bradley MPAI-A C Series Installation Instructions Manual

MP-Series Heavy-duty Electric Cylinders

Lubrication

Your electric cylinder has been lubricated at the factory and is ready for installation. Use the
appropriate lubrication interval calculations listed below for schedule estimates or use Motion
Analyzer software to calculate the recommenced re-grease schedule for the electric cylinder.
ATTENTION: Overfilling of the lubricant reservoir reduces performance, and can lead to heat
build-up and premature failure of the electric cylinder.
TIP A grease gun typically delivers one gram of lubricant for one pump of the gun.
Lubrication kits are shown on
The type of lubricant and the appropriate maintenance interval is dependent on the type of
electric cylinder and one or more usage factors:
•
Ball screw catalog number MPAI-x2xxxC does not require lubrication.
•
Ball screw (catalog number MPAI-xxxxxC or MPAI-xxxxxE) electric cylinders use
Mobilith SHC220 lubricant. A maximum case temperature above or below 50 °C
(125 °F) during operation determines the lubrication interval.
•
Roller screw (catalog number MPAI-xxxxxR or MPAI-xxxxxS) electric cylinders require
lubrication at an interval that must be calculated. Factors in the calculation include
severity of use, screw lead pitch, and frame size.
Ball Screw Lubrication
Lubrication is recommended at these intervals:
•
Light to moderate - The case temperature does not exceed 50 °C (125 °F), and does not
require additional lubrication.
•
Severe duty - The case temperature exceeds 50 °C (125 °F), and requires refilling of the
lubricant reservoir through the grease fitting at 1000 hours of use.
IMPORTANT
Use Mobilith SHC220 to lubricate the ball screw. Set your browser to

The maximum lubricant fill capacity for ball screw drives is the following:
•
3.0 g of Mobilith SHC220 for frame size 83
•
5.0 g of Mobilith SHC220 for frame size 110
•
6.0 g of Mobilith SHC220 for frame size 144
