The Bosch Rexroth BRAKING ELEMENT MBPS 5505 BS1A (R181054031) is a high-performance pneumatic braking unit designed for use with roller rail systems. This robust and maintenance-free component offers dynamic and static stabilization in the axial direction, ensuring high positioning accuracy and system reliability. The unit is capable of clamping and braking without pressurization, utilizing spring energy to maintain its hold. With an impressive service life of up to 10 million clamping cycles and up to 250,000 emergency braking operations, this braking element is built for endurance. The MBPS 5505 BS1A features integrated all-around sealing, protecting the internal mechanisms from contaminants and extending its operational lifespan. The mechanical gate valve gear mechanism provides a secure hold, while the solid steel housing with chemical nickel plating ensures durability in demanding environments. Additionally, the unit boasts low air consumption for efficient operation. Designed to be compatible with all SNS roller guide rails, it can accommodate various sizes of profiled rail systems including Size A, B, E, H, D, N profiled rail systems. The BRAKING ELEMENT can generate holding forces up to 22,000 N at a minimal release pressure of just 4 bar due to its three pistons connected in series alongside strong springs. This model operates effectively within a temperature range of -30°C to +80°C and has a nominal size that fits perfectly with corresponding guide rails and runner blocks. With air pressure requirements between 4 bar (MBPS) and 6 bar (UBPS) for operation and decompression respectively, it offers quick response times thanks to an integrated quick-exhaust valve. The BRAKING ELEMENT MBPS 5505 BS1A is designed not only for high performance but also for ease of use in various industrial applications where precision stopping or holding is critical.


Pneumatic braking unit MBPS, 55

Pneumatic braking unit MBPS, FLS for roller rail systems
Size = 55
Can be used on all SNS roller guide rails

Unpacked Weight: 3.92 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.

5.5 - 8 bar (UBPS)

Decompression with air pressure

The clamping profiles are held apart by the compressed air.

Note for mounting

Make sure the connection structure is rigid. Use only purified air. The prescribed filter mesh size is 25 μm. Observe the mounting instructions prior to commissioning. Check whether the sealing lips of the end seals are resting evenly on the roller guide rail. Realign if necessary.
