The Bosch Rexroth CLAMPING ELEMENT MK 5505 AR (R181054260) is a sophisticated pneumatic clamping unit designed for use with roller rail systems. This device ensures dynamic and static stabilization in the axial direction, offering high axial and horizontal rigidity for precise positioning and robust operation. The clamping element is compatible with various sizes of Bosch Rexroth's profiled rail systems, including sizes H, E, A, d, N, B, and S thread diameter systems. Featuring a chemically nickel-plated steel housing, the unit boasts a durable construction suitable for demanding applications. It operates using compressed air to press clamping profiles against the web surfaces of roller guide rails through a dual-acting gate valve gear mechanism. The air pressure required for clamping is adjustable from 2 to 8 bar, while decompression is facilitated by a pre-tensioned return spring enabling short decompression cycles. This model is capable of withstanding up to 1 million clamping cycles without reaching its Bd value when not using the PLUS connection. It has an air consumption norm of less than one liter per cycle and can operate within a permissible ambient temperature range of -10°C to +80°C. The unit's size and weight specifications ensure compatibility with various system configurations while maintaining ease of mounting and operational efficiency. With its spring energy holding force and continuous pressure adjustability, the Bosch Rexroth CLAMPING ELEMENT MK 5505 AR (R181054260) represents an ideal solution for users seeking reliable and precise control in their linear motion applications. Its design allows for easy integration into existing setups while providing significant improvements in performance and longevity.


Pneumatic clamping unit MK, 55

Pneumatic clamping unit MK for roller rail systems
Size = 55
Can be used on all SNS roller guide rails

Unpacked Weight: 1.928 kg
