The Bosch Rexroth CLAMPING ELEMENT KWH 5505 AS2A (R161954251) is a hydraulic clamping unit designed to provide secure and precise clamping for ball rail systems. This versatile clamping element is suitable for use with all SNS ball guide rails, ensuring broad compatibility across various applications. With its solid, rigid steel housing that's chemically nickel-plated, it offers durability and resistance to wear and corrosion. The KWH 5505 AS2A is engineered for high positioning accuracy and features a compact design that complies with DIN standards. It is equipped with an integrated all-around sealing system which, along with special pressure diaphragm technology, ensures maximum functional reliability without pressure losses or leakage. The unit's positivelocking contact profiles offer exceptional axial rigidity, contributing to the system's stability during operation. This model can achieve a holding force that varies depending on the size of the profiled rail system it is used with, and it can operate within a permissible ambient temperature range of -20°C to +80°C. The hydraulic operating pressure can be continuously adjusted from 50 to 160 bar, providing flexibility to meet different application requirements. Additionally, the clamping element boasts an impressive service life of up to 1 million clamping cycles. For ease of installation and maintenance, the KWH 5505 AS2A features threaded connections on both sides for hydraulic hook-up. Its nominal size and weight are optimized for seamless integration into existing setups without adding excessive bulk or complexity. In summary, the Bosch Rexroth CLAMPING ELEMENT KWH 5505 AS2A (R161954251) offers reliable clamping capabilities with adjustable pressure settings in a robust package designed for longevity and versatility in various industrial applications involving ball rail systems.
