Zimmer MKS3501A

Description:

The Zimmer Group MKS3501A is a pneumatic clamping element designed for linear guide systems to provide secure holding and positioning of moving axes. It features 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 uses a wedge-type transmission system to generate high holding force and is built for durability and long service life in industrial automation environments.

Applications:

The Zimmer Group MKS3501A 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 35) to hold axes in position, stabilize movement, and maintain safe clamping during energy loss or system shutdown conditions.
