Reversible Cam

ROTEX features on demand Reversible Cam construction. The profile can be easily dismantled and reversed on line. The repeatability and the functional accuracy does not change.

List Of Accessories

Features

• All the power cylinders can be supplied with optional accessories. Some accessories are factory fitted. Some can be installed at the later stage. It is highly recommended that you consult ROTEX for complete installation, application, etc. Air lock relays are more practical to be considered during various power failure made.
• POWER CYLINDER : Rotex power cylinder can be installed in various corrosive environments by selecting suitable material. Bellows and guards can be provided for physical protection.

Material of Construction

Cylinder Mountings as per ISO 6431 and ISO 6432. All accessories can be installed or dismantled without removing cylinder covers.

Options
Manual Override
