The Bosch Rexroth CLAMPING ELEMENT MKS 2505 AK (R161924060) is a pneumatic clamping unit designed for use with ball rail systems. This robust clamping element ensures dynamic and static stabilization in the axial direction, employing a straightforward mechanical gripping principle that delivers an excellent price-performance ratio. Its chemically nickel-plated steel housing provides high axial and horizontal rigidity, which contributes to precise positioning capabilities. With the ability to be mounted on all SNS ball guide rails, this clamping element offers easy installation and operates by clamping without pressurization using spring energy. In case of a pressure drop, it engages via a dual-action gate valve gear mechanism with two spring assemblies. The integrated quick-exhaust valve featured in this unit significantly reduces response times, making it highly efficient for applications requiring quick movements. The MKS 2505 AK can withstand a maximum permissible ambient temperature ranging from -10°C to +80°C and is compatible with various sizes of profiled rail systems including Size A, Size B, Size D, Size E, Size H, and Size N. It has been designed for a high number of clamping cycles—up to 1 million—ensuring longevity and reliability in demanding operational conditions. This pneumatic clamping unit also boasts higher holding force due to its airplus port feature. The release pressure stands at 4 bar for the standard air port and 4.5 bar for the airplus port. With its nominal size precision and compatibility with accessories for profiled rail systems, the Bosch Rexroth CLAMPING ELEMENT MKS 2505 AK is an ideal solution for ensuring accurate positioning and powerful drive in linear motion applications.

Functional principle
Clamping with air pressure or spring force
Clamping profiles are pressed to the web surfaces of the Ball Guide Rail.
Decompression with air pressure or spring force
The clamping profiles are held apart. Free movement is possible
