Clamping Actuators

Clamping actuators are tools used to grip and hold equipment or materials. The clamps secure the actuator rod in a vertical position and prevent it from retracting, which is essential for operator safety.

They have spring-like mechanisms that are kept in an open position by the pressure in the pneumatic system. If a drop in pressure occurs because of a leak, the clamps will snap closed and secure the rod until the air pressure is normalised.

What are clamping actuators used for?

Clamping actuators secure equipment while repairs take place or while materials are being handled. They are typically found in robotics processes within the automotive and manufacturing industries.

Types of clamping actuators

Clamping actuators come in single-acting, double-acting and through-rod variants and designs for specific applications. These include:

  • Rotary clamping actuators – operate on lubricated compressed air with an clamp arm attachment to secure the equipment or materials.
  • Pancake clamping actuators – can operate with lubricated or unlubricated compressed air and are ideal for small spaces due to their compact size.
  • Pin clamping actuators – have pins that allow for precise positioning as well as clamping.
