The Bosch Rexroth BRAKING ELEMENT MBPS 3505 AS1A (R161934031) is a high-performance pneumatic braking unit designed for dynamic and static stabilization in the axial direction of ball rail systems. This robust component can be utilized across various sizes of SNS ball guide rails, including Size B, E, H, A, D, N profiled rail systems. It features integrated all-around sealing and a solid, rigid steel housing that is chemically nickel-plated for enhanced durability. With the ability to achieve up to 1 million clamping cycles and up to 250,000 emergency braking operations without maintenance, this braking element is built for longevity and reliability. Its mechanical gate valve gear mechanism ensures high positioning accuracy and continuous output. The unit operates efficiently with low air consumption and maintains its holding forces up to 22,000 N at just 5.5 bar release pressure thanks to its innovative design with three pistons connected in series combined with strong springs. The BRAKING ELEMENT MBPS 3505 AS1A also boasts an impressive Bd value; however, it should be noted that the Bd value is not attained with the PLUS connection. It has a permissible ambient temperature range from -30°C to +80°C and can accommodate various runner block heights depending on the guide rail size. The air consumption is rated at a normal liter standard air port G1/4. For safety and functionality, it clamps and brakes with spring force in case of pressure drop using a dual-acting gate valve gear mechanism with spring energy accumulators. An integrated quick-exhaust valve ensures rapid reaction times for optimal performance. The nominal size of the unit corresponds to its compatibility with different profiled rail system sizes while maintaining a weight specification of 2.3 kg. This makes the Bosch Rexroth BRAKING ELEMENT MBPS 3505 AS1A an essential component for applications requiring precise motion control and safety within pneumatic systems.
