Cleaning
Actuator external surfaces may be cleaned with a clean, dry cloth. Use only mild, non-corrosive cleaning agent. Keep strip
seal clear of debris. Inspect area around carriage for signs of contamination. Keep the strip seal free of debris. Environ-
ments with high concentrations of small particles, such as metal shavings, dust, and sawdust may require the ER unit to
be fitted with a positive pressurization tube and fitting. Call the factory for details at (330) 336-3511.
Do not use high pressure washdown or steam-lance cleaning systems.
Lubrication
ER Series actuators are lubricated upon assembly. In most cases, this lubrication will suffice for the life of the actuator.
Applications that require high speeds, high duty cycles or strokes that do not allow ball nut ball bearings to completely
recirculate may require additional lubrication. The angular contact thrust bearings are lubricated for life, as are the roller
bearing wheels. Square rail bearings supplied with ER Series actuators typically require no additional lubrication.
To inspect the ball screw or acme lead screw to determine if lubrication is necessary, remove the strip clamps from either
end cap and lift the strip seal. Be careful not to pull on the seal. With the drive screw exposed, verify that an adequate
amount of lubrication is present on the screw threads. Should additional lubrication be required, Parker AAD recommends
the following:
• MagnaLube (p/n 1331815-000-01), 1.5 oz tube (grease)
• Thomson Linear Lube, 14.5 oz tube (grease)
Depending on the conditions of use, it may be necessary to establish a lubrication schedule for your actuator. Please
contact the factory at (330) 336-3511 for additional information.
