Zimmer MKS5501A Linear Clamping Element, Normally Closed, 1450N Holding, 6bar

Description:

The Zimmer Group MKS5501A is a pneumatic linear clamping element designed for securing and positioning linear guide systems in industrial automation. It uses a spring-loaded energy storage mechanism that clamps without air pressure (normally closed) and releases when compressed air is applied, ensuring fail-safe operation during power or pressure loss. The unit utilizes a wedge-type transmission system to generate high holding force and maintain precise positioning with minimal movement.

Applications:

The Zimmer Group MKS5501A clamping element is used in linear motion systems such as CNC machinery, robotics, assembly lines, and automated production equipment. It is commonly installed on profile rail guides (size 55) to hold axes in position, reduce vibration, and maintain safe stopping or holding during operation or system shutdown.
