Pneumatic braking unit MBPS, 20

Pneumatic braking unit MBPS, FLS for ball rail systems
Size = 20
Can be used on all SNS ball guide rails

Unpacked Weight: 0.553 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 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.

Note for mounting

Make sure the connection structure is rigid. Use only purified, lubricated air. The prescribed filter mesh size is 25 μm. Observe the mounting instructions prior to commissioning. Check whether the sealing lips of the front seals are resting evenly on the Ball Guide Rail. Realign if necessary.
