Installation note:
Maintain 0.5mm minimum clearance between rod end and load during alignment.
Use locknuts with 25–30 N·m torque for mounting brackets. Lubricate through
air supply (oil-fog lubrication) at 1 drop/minute/1 m³ airflow.
Critical parameters:
Max side load capacity 35N at mid-stroke. Avoid continuous operation above
70℃ ambient temperature. Requires 5μm filtered air with dew point -15℃ below
environmental temperature.
