The Bosch Rexroth CLAMPING ELEMENT KWH 3505 BS1A (R181034211) is a hydraulic clamping unit designed for precision and durability in various applications. This unit is 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 a wide range of industrial settings. Constructed from solid, rigid steel with a chemically nickel-plated finish, the KWH 3505 BS1A boasts high positioning accuracy and can withstand up to 1 million clamping cycles. The pressure is continuously adjustable from 50 to 450 bar, catering to different operational needs without compromising on reliability or performance. The product features an integrated all-around sealing and utilizes special pressure diaphragm technology that ensures maximum functional reliability without pressure losses or leakage. The clamping element also includes integrated positive-locking, large-surface contact profiles for exceptional axial rigidity. It operates within a permissible ambient temperature range of -20°C to +80°C, making it suitable for various environmental conditions. Its hydraulic operation requires pressures between 50 and 450 bar, while decompression is facilitated by a pre-tensioned return spring for rapid cycle times. This hydraulic clamping unit has threaded connections on both sides for hydraulic linking and comes in several sizes compatible with B, H, E, A, S, and N profiled rail systems. With its nominal size precision and weight of approximately 2.8 kg, the KWH 3505 BS1A is engineered to meet stringent technical specifications while providing robust clamping force necessary for secure operations across a multitude of applications.

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
