The Bosch Rexroth BRAKING ELEMENT KBH 4505 BS3A (R181044022) is a robust hydraulic braking unit designed for roller rail systems. This heavy-duty brake element is engineered to provide dynamic and static stabilization in the axial direction, ensuring high positioning accuracy and operational reliability. It features an integrated all-around sealing mechanism that prevents pressure losses or leakage, making it suitable for demanding industrial applications. With a capacity of up to 2 million clamping cycles and the ability to handle up to 250,000 emergency braking operations, the KBH 4505 BS3A demonstrates exceptional durability. The unit's brake shoes boast integrated positive-locking contact profiles that deliver maximum axial rigidity, contributing to the system's overall stability and performance. Constructed with a solid, rigid steel housing that is chemically nickel-plated, this clamping and braking unit is built to withstand harsh conditions while maintaining a compact design compatible with DIN standards. It can be used on all SNS roller guide rails and comes equipped with threaded connections on both sides for easy hydraulic integration. The KBH 4505 BS3A operates at a release pressure of 50 bar and utilizes special pressure diaphragm technology to ensure maximum functional reliability. Its low displacement value signifies efficient operation, while the nominal size and compatibility with various profiled rail systems (sizes A, B, E, H, N) make it versatile for different linear guide types. The functional principle of this braking element involves clamping profiles being pressed directly through hydraulic oil via a piston principle onto the Roller Guide Rail flanks at a hydraulic pressure of up to 350 bar. Decompression occurs swiftly thanks to a pre-tensioned return spring. Overall, this Bosch Rexroth hydraulic braking unit is an essential component for profiled rail systems requiring high holding force (specified in Bd value), precision in positioning, and reliable operation within permissible ambient temperatures ranging from -30°C to +80°C.
