The Bosch Rexroth BRAKING ELEMENT KBH 4505 BS1A (R181044021) is a robust hydraulic braking unit designed for high-precision and heavy-duty applications. This unit is specifically engineered to be compatible with all SNS roller guide rails, providing dynamic and static stabilization in the axial direction. With its compact design, it meets DIN standards and can be seamlessly integrated into existing systems. The KBH 4505 BS1A boasts up to 1 million clamping cycles and can handle up to 250,000 emergency braking operations, making it suitable for continuous use in demanding environments. Its solid, rigid steel housing is chemically nickel-plated to ensure durability and resistance to harsh conditions. The brake's high positioning accuracy is facilitated by a release pressure of 50 bar and an integrated all-around sealing that employs special pressure diaphragm technology for maximum functional reliability without pressure losses or leakage. Furthermore, the brake shoes feature integrated positive-locking with large-surface contact profiles that contribute to maximum axial rigidity. This super heavy-duty model has a low displacement value with a Bd value indicating its efficiency in clamping cycles. It operates within a permissible ambient temperature range of -20°C to +80°C and can withstand a maximum hydraulic operating pressure of 350 bar. The BRAKING ELEMENT KBH 4505 BS1A also includes threaded connections on both sides for the hydraulic connection, ensuring easy installation and maintenance. Its functional principle involves hydraulic pressure clamping or braking with pressure up to 350 bar while decompression is achieved with spring force from a pretensioned return spring for quick decompression cycles. Designed for use with various sizes of profiled rail systems including sizes A, B, E, H, N, and S, this unit offers flexibility across different applications. It also comes equipped with accessories for profiled rail systems as part of its comprehensive package. The weight of the unit is approximately 7 kg which adds minimal load to machinery while maintaining performance efficiency.
