What is the Bosch Rexroth R181024051?

Pneumatic braking unit UBPS *) , FLS for roller rail systems

Size = 25

Can be used on all SNS roller guide rails

*) Zimmer GmbH

Clamps and brakes with spring energy accumulator

Positive-locking integrated contact profiles ensure maximum axial and horizontal rigidity, and thus an excellent braking effect

Dynamic and static stabilization in the axial direction

Clamps and brakes without pressurization (spring energy)

Compact design, compatible with DIN 645

Up to 1 million clamping cycles

Up to 2,000 emergency braking operations

Integrated all-round sealing

High continuous output

High positioning accuracy

Mechanical gate valve gear mechanism

Solid, rigid steel housing, chemically nickel-plated

Extremely low air consumption

Maintenance-free

5 million clamping cycles (B10d value) – the B10d value is not attained with the PLUS connection

Can be used on all SNS roller guide rails

Very high axial holding forces of up to 7700 N at 5.5 bar release pressure with high-power spring energy accumulator

Increased holding force of up to 9,200 N thanks to additional pressurization on the air-plus port
