The Bosch Rexroth CLAMPING ELEMENT KWH 2505 BS3A (R181024231) is a hydraulic clamping unit designed for high precision and reliability in industrial applications. This unit is engineered to be compatible with all SNS roller guide rails, offering dynamic and static stabilization in the axial direction. Its compact design adheres to DIN standards, ensuring seamless integration into various systems. With the ability to exert a continuously adjustable pressure from 50 to 450 bar, this clamping element provides versatility across different operational requirements. The solid steel housing is chemically nickel-plated for durability and resistance to harsh environments, while the integrated all-around sealing prevents contamination and maintains functional integrity. The KWH 2505 BS3A boasts special pressure diaphragm technology that ensures maximum reliability without pressure losses or leakage. It also features integrated positive-locking contact profiles that contribute to exceptional axial rigidity and precision during use. This model has been tested for up to 10 million clamping cycles, demonstrating its longevity and consistent performance over time. This particular clamping element can operate within a permissible ambient temperature range of -20°C to +80°C, accommodating various working environments. It has been designed with threaded connections on both sides for the hydraulic connection, making installation straightforward and secure. Overall, the Bosch Rexroth CLAMPING ELEMENT KWH 2505 BS3A offers a robust solution for securing components with high holding force while maintaining precise positioning accuracy in demanding industrial settings. Its innovative design ensures reliable operation cycle after cycle, making it an essential component for profiled rail systems requiring hydraulic clamping capabilities.
