The Bosch Rexroth BRAKING ELEMENT UBPS 2505 AS1A (R161924051) is a high-performance pneumatic braking unit designed for use with ball rail systems. This robust component is suitable for various sizes of profiled rail systems, including sizes B, H, E, d, and N. It offers a compact design that is compatible with DIN standards and is capable of providing dynamic and static stabilization in the axial direction. The braking element clamps and brakes without pressurization using spring energy and boasts an extremely low air consumption. With a solid, rigid steel housing that's chemically nickel-plated, the UBPS 2505 AS1A ensures durability and maintenance-free operation for up to 10 million clamping cycles. It also supports up to 100,000 emergency braking operations. Its integrated all-around sealing contributes to its high continuous output and positioning accuracy. The pneumatic operating pressure ranges between 4-6 bar for the UBPS model, with a maximum permissible pressure detailed for specific profiled rail system sizes. The unit's functional principle involves clamping and braking with spring force; in the event of a pressure drop, it achieves clamping or braking effect through a dual-acting gate valve gear mechanism with one spring assembly spring energy accumulator each. This braking element can exert very high axial holding forces of up to 25,000 N at 4 bar release pressure due to its high-power spring energy accumulator. An additional pressurization on the airplus port can increase this holding force up to 50,000 N. The product also features an integrated quick-exhaust valve for fast reaction times. Designed to be maintenance-free with exceptional performance longevity, this Bosch Rexroth pneumatic braking unit is an essential accessory for ensuring precise control and safety in applications involving profiled rail systems.

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 achieved via a dual acting gate valve gear mechanism with one spring assembly (spring energy accumulator) in each case.
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.
