Same Technical Performance for Harsher Environments

Camtorc Extreme Service Actuators (Type SX & CX)

Camtorc actuators are specified and operate in some of the World’s most critical and demanding applications as found in the oil and gas, energy and marine industries.

Camtorc Extreme Services Actuators, offer the same innovation and reliability found in all Camtorc actuators, but with the technical performance to operate in the harshest and most demanding environments.

Features and Benefits

Cam Design

The unique cam design offers a highly efficient and simple, backlash free operation providing extended life of seals and components

High Integrity Construction

Constructed in 316 (CF8M) stainless steel and fully tested on assembly to provide superior operational life

Full Torque Output

The pneumatic spring return version at the beginning of the spring stroke has a 15% increase in torque output, providing extra power for the break torque and at the end of the spring, the torque output is the same as that of the double acting variant of the actuator


Compact Dimensions

The high torque output of the pneumatic spring return version allows for the use of smaller size actuators than is the case with conventional actuator designs

Long Spring Life

All springs are stress relieved after forming to ensure a long life

Whole Life Cost

Camtorc actuators are exceptionally low wearing providing low maintenance and the optimum Whole Life Cost solution for the customer

The Extreme Actuator Design includes:

0° to 95° rotation with adjustable end stops

Torque Range
Double Acting: 10 to 30,000 Nm / Spring Return: 10 to 20,000 Nm (Spring End)

Supply Pressure Range
