The Bosch Rexroth CLAMPING ELEMENT KWH 5505 BS3A (R181054231) is a high-performance hydraulic clamping unit designed for use with SNS roller guide rails. This robust clamping element boasts a solid, rigid steel housing that is chemically nickel-plated, ensuring durability and resistance to corrosion. It is engineered to deliver dynamic and static stabilization in the axial direction, which is critical for maintaining precision in various applications. Equipped with an integrated all-around sealing system, the KWH 5505 BS3A ensures maximum functional reliability without pressure losses or leakage, thanks to its special pressure diaphragm technology. The clamping element provides high positioning accuracy and can achieve up to 1 million clamping cycles, attesting to its long service life and reliability. This model features a compact design that complies with DIN standards, making it compatible with multiple rail systems including sizes A, B, E, H, N profiled rail systems. The hydraulic connection is threaded on both sides for ease of installation. The unit offers continuously adjustable pressure from 0 bar upwards and has been tested for holding force in accordance with ISO VG standards. The KWH 5505 BS3A operates using a hydraulic pressure of up to 450 bar for clamping and braking applications. Decompression occurs through spring force facilitated by a pre-tensioned return spring which allows for short decompression cycles. This product's versatility extends to its ability to function within a permissible ambient temperature range from -20°C up to +80°C. Overall, the Bosch Rexroth CLAMPING ELEMENT KWH 5505 BS3A stands out as an essential component for users requiring precise control over their roller guide rail systems in various demanding environments where stability and accuracy are paramount.

Notes 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 end seals are resting evenly on the roller guide rail. Realign if necessary.

Notes on lubrication

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