Mount the Electric Cylinder
Follow these steps to mount the electric cylinder on the machine.
1.
Verify the mounting surface flatness.
The mounting surface must be flat or shimmed flat to the mounting surface of the
electric cylinder within 0.127 mm (0.005 in.) to avoid distortion and damage to the
actuator housing.
2.
Install and evenly tighten the steel fasteners so the electric cylinder is securely mounted
on the machine before thrust rod alignment is performed.
3.
Align the electric cylinder as shown in the diagram and described below.
Align the thrust rod of the electric cylinder parallel to the load supporting bearing
system in both flatness and straightness within these specifications:
•
With thrust rod extended <0.254 mm (0.010 in.) parallel to the load guides.
•
With thrust rod retracted <0.127 mm (0.005 in.) parallel to the load guides.
4.
Torque the steel fasteners evenly to 39.5 N•m (350 lb•in), and then verify the thrust rod
alignment remains within specifications.
ATTENTION:
When installed, pinch points with high forces are created that have the potential for
causing physical damage. The risk area surrounding the electric cylinder must be enclosed or
clearly marked, including signage in accordance with national and international requirements.
The risk area must be protected by a safety system that stops the equipment if anyone enters the
risk area. Personnel who enter the risk area must be authorized, trained, and qualified for any task
performed inside the risk area.
