The Bosch Rexroth CLAMPING ELEMENT KWH 4505 AS1A (R161944211) is a robust hydraulic clamping unit designed for high-precision applications. This unit is specifically engineered to be compatible with all SNS ball guide rails, enhancing its versatility across various profiled rail systems including sizes A, B, E, H, N, and S. It boasts an integrated all-around sealing and a compact design that adheres to DIN standards, ensuring a secure fit in diverse operating environments. With its solid and rigid steel housing that is chemically nickel-plated, the KWH 4505 AS1A promises durability and resistance against corrosion. The clamping element features special pressure diaphragm technology which guarantees maximum functional reliability without any pressure losses or leakage. It also comes with integrated positive-locking contact profiles that provide maximum axial rigidity. The unit's high positioning accuracy is ideal for tasks requiring precision, and it can sustain up to 10 million clamping cycles (Bd value), signifying its long service life. The hydraulic pressure can be continuously adjusted from 50 to 450 bar allowing for optimal customization according to specific requirements of the application. Furthermore, the KWH 4505 AS1A operates effectively within a permissible ambient temperature range of -20°C to +80°C. It has been designed with threaded connections on both sides for ease of hydraulic integration. For safety and reliability in operation, the clamping element incorporates a pretensioned return spring which enables short decompression cycles after pressurization. This clamping unit's nominal size accommodates various runner block heights and widths while maintaining an impressive holding force at different pressures as detailed in the technical data provided by Bosch Rexroth. With its meticulous design focused on efficiency and reliability, this hydraulic clamping element is an essential component for users seeking enhanced stability in their linear guide applications.
