The Bosch Rexroth CLAMPING ELEMENT MK 2505 AK (R161924260) is a high-performance pneumatic clamping unit designed for use with ball rail systems. This robust and reliable element is engineered to provide dynamic and static stabilization in the axial direction, ensuring precise positioning and high rigidity during operation. The simple mechanical gripping principle allows for easy mounting and efficient operation, making it an ideal choice for applications requiring exact motion control and long service life. The clamping unit operates by pressing the clamping profiles against the web surfaces of the ball guide rail using compressed air delivered through a dual-acting gate valve gear mechanism. This action can be adjusted continuously with an operating pressure range from 0 to 8 bar, allowing users to customize the force applied based on their specific requirements. Decompression is swiftly achieved with spring force thanks to a preloaded return spring, facilitating short decompression cycles and enhancing overall efficiency. Constructed with a chemically nickel-plated steel housing, the MK 2505 AK offers exceptional axial and horizontal rigidity, contributing to its precise positioning capabilities and high dynamics. It's also built for durability, boasting an impressive Bd value of 1 million clamping cycles. The unit is versatile enough to be used on all SNS or BNS ball guide rails, accommodating various sizes of runner blocks and profiled rail systems. Furthermore, this clamping element operates effectively within a wide temperature range of -10°C to +80°C, ensuring reliable performance across different working environments. The nominal size of the CLAMPING ELEMENT MK 2505 AK reflects its compatibility with multiple rail system sizes while maintaining a manageable weight that contributes to its ease of installation and maintenance. In summary, the Bosch Rexroth CLAMPING ELEMENT MK 2505 AK (R161924260) stands out as a sophisticated solution for securing components in place with precision and strength in demanding linear motion applications.
