The Bosch Rexroth CLAMPING ELEMENT MKS 4505 AR (R181044060) is a high-quality pneumatic clamping unit designed for use with roller rail systems. This robust clamping element can be mounted on all SNS roller guide rails, offering both dynamic and static stabilization in the axial direction. Its installation process is straightforward, ensuring a hassle-free setup. The unit boasts a chemically nickel-plated steel housing that provides exceptional axial and horizontal rigidity, contributing to precise positioning and higher holding force, especially when utilizing the airplus port. It is engineered for demanding applications requiring reliable clamping without pressurization, as it employs a dual-action gate valve gear mechanism with two spring assemblies to secure components in place even in the event of a pressure drop. With the ability to perform over 1 million clamping cycles, this clamping element is designed for longevity and sustained performance. The product is suitable for various sizes of profiled rail systems including Size B, H, E, A, D, d, N and accommodates different heights of runner blocks. The nominal size and weight are optimized for compatibility with these systems. The functional principle of the MKS 4505 AR involves clamping with spring force at a standard air pressure of 6 bar while allowing decompression at an air pressure range between 4 to 6 bar. It includes an integrated quick-exhaust valve for rapid reaction times and ensures free movement when decompressed by compressed air. This Bosch Rexroth pneumatic clamping unit operates efficiently within a permissible ambient temperature range from -10°C to +80°C. It has been specifically designed to offer increased holding force through additional air admission at the airplus port with 6 bar pressure and can be controlled via 3 or 4-way directional control valves. The product ensures precise linear guidance as an accessory for profiled rail systems and maintains its functionality even under maximum pneumatic operating pressures.

Unpacked Weight: 1.806 kg

Functional principle

Air pressure: 0 bar

Clamps with spring force

In the event of a pressure drop, the MKS clamps via a dual acting gate valve gear mechanism, each with one spring assembly (spring energy accumulator).

An integrated quick-exhaust valve provides for short reaction times.
