Description
- 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)
- Clamping and braking units in short format
Features
- Up to 1 million clamping cycles
- Up to 2,000 emergency braking operations
- Integrated all-around sealing
- High continuous output
- High positioning accuracy
- Mechanical gate valve gear mechanism
- Solid, rigid steel housing, chemically nickel-plated
- 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 Ball Guide Rails
- Add-ons with three pistons connected in series combined with strong springs result in holding forces up to 3,800 N at just 4.5 bar release pressure
Product description
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.
- Free movement is possible
