The Bosch Rexroth CLAMPING ELEMENT KWH 5505 AS3A (R161954231) is a hydraulic clamping unit designed for high precision and reliability in securing ball rail systems. This robust clamping element can be used with all SNS ball guide rails, showcasing its versatility across different rail sizes including Size A, B, E, H, N and S profiled rail systems. It features a solid, rigid steel housing with a chemically nickel-plated finish that ensures durability and resistance to harsh conditions. The clamping element operates on a hydraulic pressure range of 50 to 250 bar and employs special pressure diaphragm technology which guarantees maximum functional reliability without pressure losses or leakage. Its integrated positivelocking with large-surface contact profiles provides exceptional axial rigidity. The unit is capable of achieving high positioning accuracy and boasts an impressive service life with up to 10 million clamping cycles. Designed for compactness and ease of integration, it includes an all-round sealing to protect against contaminants. The pressure can be continuously adjusted according to the requirements of the application, ensuring precise control over the holding force which is critical for various positioning tasks. The KWH 5505 AS3A also has threaded connections on both sides for hydraulic connections, simplifying installation and maintenance. This model's nominal size fits Size H profiled rail systems particularly well, while still being compatible with other sizes through its adaptable design. It has been tested for performance in a temperature range from -20°C up to +80°C, ensuring reliable operation in varying environmental conditions. With a weight of just 0.9 kg, it remains lightweight yet sturdy enough to maintain stability under load. In summary, the Bosch Rexroth CLAMPING ELEMENT KWH 5505 AS3A is engineered for secure clamping in demanding applications where precision and longevity are paramount. Its advanced design features meet the needs of sophisticated linear motion systems requiring dependable clamping solutions.
