INSTALLATION
Mechanical Installation
Lubrication
EL series actuators are shipped from the factory fully greased and ready for installation.
Exlar
’s standard grease is Mobil SHC 220, which is a high performance, extreme-pressure
grease. SHC 220 is adequate for a broad range of applications. In the case of extreme
temperatures, Exlar recommends using Mobilgrease 28, also a high performance, extreme-
pressure grease. The unique physical properties of the synthetic base oil provide
outstanding protection against wear, rust, corrosion, and high or low-temperature
degradation. Mobilgrease 28 allows for very low starting and running torque values. Its
operating range is -55 to 180 °C (-67 to 356 °F).
Other lubricants can be used as well and all special grease can be specified via
the “XL”
designation in the Options portion of the model mask with the appropriate product identified
with Exlar Application engineering at the time of order.
Mounting Configurations
The actuator have provisions for front face, rear face, front flange, rear eye, or rear
clevis mounting. Every effort should be made to minimize misalignment. Any misalignment
will decrease the life of the components within the actuator and also may create problems
within the application associated with misalignment.
See an Exlar catalog or Exlar Supplied mounting drawing for the specific mounting
dimensions required for your configuration.
