The Bosch Rexroth CLAMPING ELEMENT KWH 2505 AS2A (R161924251) is a high-performance hydraulic clamping unit designed for ball rail systems. This robust and compact clamping element can be utilized on all SNS ball guide rails, offering dynamic and static stabilization in the axial direction. Its solid, rigid steel housing is chemically nickel-plated to ensure durability and resistance to corrosion. The KWH 2505 AS2A features an integrated all-round sealing and special pressure diaphragm technology that provides maximum functional reliability without pressure losses or leakage. With its high positioning accuracy and the ability to continuously adjust pressure from 0 to 250 bar, this clamping element meets the demands of various applications requiring precise motion control. It includes positivelocking, large-surface contact profiles which contribute to maximum axial rigidity, ensuring that it can withstand up to 10 million clamping cycles. The size compatibility of the KWH 2505 AS2A extends across multiple profiled rail system sizes including B, E, A, N, H, and S thread diameter profiled rail systems. It has a holding force capability that varies with hydraulic pressure and can operate within an ambient temperature range of -20°C to +80°C. The nominal size of the unit is complemented by a weight of approximately 1.9 kg for size H profiled rail systems. Designed for ease of use, this clamping element comes with threaded connections on both sides for the hydraulic connection. The functional principle relies on hydraulic oil pressing large-scale clamping profiles onto the flanks of the Ball Guide Rail via a piston mechanism when pressurized; decompression occurs through spring force facilitated by a pretensioned return spring for quick cycle times. This makes the Bosch Rexroth KWH 2505 AS2A an essential component for applications requiring reliable and efficient clamping capabilities in linear motion systems.
