Zimmer MK2501A Clamping Element
The Zimmer MK2501A Clamping Element is a high-performance pneumatic clamping device designed to securely lock linear guide carriages in demanding industrial automation applications. Manufactured by Zimmer Group, the MK Series delivers reliable holding force, excellent positioning accuracy, and long service life, making it an ideal solution for CNC machines, robotics, automation systems, and precision assembly equipment.
The MK2501A features a Normally Open (NO) operating principle. Without air pressure, the clamp remains open, while compressed air activates the clamping mechanism to firmly secure the linear guide carriage. Its wedge-type transmission design ensures high rigidity, vibration reduction, and precise positioning during operation.
