The Bosch Rexroth CLAMPING ELEMENT MK 4505 AR (R181044260) is a high-precision pneumatic clamping unit designed for use with SNS roller guide rails, offering dynamic and static stabilization in axial direction. This unit is notable for its ease of mounting and its ability to provide precise positioning and high rigidity both axially and horizontally. The clamping mechanism operates by pressing the clamping profiles to the web surfaces of the roller guide rail via compressed air propelled through a dual-acting gate valve gear mechanism. With a chemically nickel-plated steel housing, this clamping element ensures durability and resistance to wear, which contributes to its long service life. It is capable of up to 1 million clamping cycles and allows for continuously adjustable pressure ranging from 2-6 bar. The MK 4505 AR can be used across various sizes of profiled rail systems, including H, E, A, d, N, B, and S series with corresponding runner block dimensions. The unit's functional principle involves clamping with air pressure at 2-6 bar while decompression occurs swiftly using spring force thanks to a pre-tensioned return spring. This feature enables short decompression cycles which are essential for fast-paced operations. The permissible ambient temperature range for operation extends from -10°C up to +80°C. It has an impressive spring energy holding force when operated at standard air port pressure of 4 bar. With a nominal size that fits multiple rail system sizes and an M8 thread diameter for the S size profiled rail systems, this element is versatile in application. Its weight stands at approximately 0.7 kg, making it a robust yet manageable component in linear motion systems. In summary, the Bosch Rexroth CLAMPING ELEMENT MK 4505 AR (R181044260) represents a reliable solution for pneumatic clamping needs within various industrial applications requiring precise linear motion control.
