The Bosch Rexroth BREMSELEMENT MBPS 3505 BS1A (R181034031) is a state-of-the-art pneumatic braking unit designed for high-precision applications requiring dynamic and static stabilization in the axial direction. This robust component is suitable for all SNS roller guide rails and ensures maintenance-free operation with up to 10 million clamping cycles and up to 250,000 emergency braking operations. The integrated all-around sealing contributes to its high durability and consistent performance. With its solid, rigid steel housing that is chemically nickel-plated, the MBPS 3505 BS1A offers exceptional strength and resistance to wear. It features a mechanical gate valve gear mechanism that allows for clamping and braking without pressurization using spring energy. This results in a safe holding force even in the event of a power loss. The unit's design includes addons with three pistons connected in series along with strong springs, which can deliver holding forces up to 22,000 N at just 5.5 bar release pressure, ensuring high positioning accuracy and reliability under various operating conditions. The permissible ambient temperature range for this model spans from -30°C up to +80°C, allowing for operation in diverse environments. Furthermore, the MBPS 3505 BS1A boasts a low air consumption rate with a nominal size of the air port and an integrated quick-exhaust valve that ensures short reaction times. It is compatible with various profiled rail systems including Size A, B, D, E, H, N, and S thread diameter systems. The weight of the unit is specified at 2.7 kg. In summary, the Bosch Rexroth BREMSELEMENT MBPS 3505 BS1A (R181034031) pneumatic braking unit is an efficient and reliable solution for securing mechanical components with precision clamping and braking capabilities across a wide range of industrial applications.

Unpacked Weight: 1.443 kg
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.
