The Bosch Rexroth BRAKING ELEMENT UBPS 2505 BS1A (R181024051) is a sophisticated pneumatic braking unit designed to provide dynamic and static stabilization in the axial direction for roller rail systems. This high-performance component boasts a solid, rigid steel housing that is chemically nickel-plated, ensuring durability and resistance to wear. It is engineered for compatibility with DIN standards and can be used on all SNS roller guide rails, making it versatile for various applications. With the capability of up to 1 million clamping cycles and up to 250,000 emergency braking operations, this braking element ensures reliability and longevity in demanding operational conditions. Its integrated all-around sealing contributes to its maintenance-free nature, while the mechanical gate valve gear mechanism facilitates high continuous output and precise positioning accuracy. The UBPS 2505 BS1A operates efficiently with extremely low air consumption and includes an integrated quick-exhaust valve for rapid reaction times. The clamping profiles can be held apart by compressed air allowing free movement when necessary. It provides very high axial holding forces of up to 25 kN at 5 bar release pressure with a high-power spring energy accumulator. Additionally, the holding force can be increased up to 50 kN through additional pressurization on the Airplus port. This braking element operates within a permissible ambient temperature range of -30°C to +80°C and has been designed with a focus on safety; in the event of a pressure drop, it generates clamping or braking effect via a dual-acting gate valve gear mechanism equipped with spring assemblies as energy accumulators. The UBPS 2505 BS1A is suitable for various profiled rail systems including sizes A, B, E, H, N, d, and S thread diameter profiled rail systems M6. It has a nominal size indication and weighs approximately 2.7 kg. The functional principle of this unit relies on air pressure ranging from 4 bar (for clamping and braking with spring force) to 6 bar (for decompression with air pressure), offering flexibility according to operational requirements.

Functional principle
Air pressure: 0 bar
Clamps and brakes with spring force
In the event of a pressure drop, the clamping or braking effect is generated via a dual acting gate valve gear mechanism, each with one spring assembly (spring energy accumulator).
An integrated quick-exhaust valve provides for short reaction times.
Air pressure: 4.5 - 8 bar (MBPS)
5.5 - 8 bar (UBPS)
Decompression with air pressure
The clamping profiles are held apart by the compressed air.
