The Bosch Rexroth CLAMPING ELEMENT KWH 2505 AS1A (R161924211) is a hydraulic clamping unit designed for high precision and reliability in securing ball rail systems. This robust unit is compatible with all SNS ball guide rails, ensuring broad application across various rail sizes including Size A, B, E, H, N, and S profiled rail systems. The KWH 2505 AS1A showcases an integrated all-round sealing and special pressure diaphragm technology that provides maximum functional reliability without pressure losses or leakage. Constructed from a solid, rigid steel housing that is chemically nickel-plated, this clamping element offers high positioning accuracy and the ability to withstand demanding operational conditions. It features a compact design that adheres to DIN standards and allows for easy integration into existing systems. The hydraulic connection is threaded on both sides for convenience. This model operates on a functional principle where hydraulic pressure up to bar clamps with pressure directly onto the flanks of the Ball Guide Rail through a piston mechanism. Decompression occurs rapidly thanks to a pre-tensioned return spring which enables short decompression cycles. The unit boasts an impressive holding force and can maintain its performance over million clamping cycles. Additionally, it can operate within an ambient temperature range from - C to C. The KWH 2505 AS1A's nominal size and weight specifications cater to various system dimensions while maintaining a height of runner block with guide rail compatibility. In terms of maintenance and inspection, the process is facilitated in its mounted state with lubrication conforming to ISOVG standards. For technical data regarding permissible holding forces and additional calculations, users are directed towards the product's technical documentation.

Note for mounting

Stop surfaces can be used on two sides. Make sure the connection structure is rigid. Observe the mounting instructions prior to commissioning. Check whether the sealing lips of the front seals rest evenly on the Ball Guide Rail. Realign if necessary.

Notes on lubrication

Initial filling of hydraulic oil HLP46 Check for compatibility when using different oils
