Description
- High axial holding forces with short format
- Dynamic and static stabilization in the axial direction
- Easy mounting
- Clamps without pressurization (spring energy). In the event of a pressure drop, it clamps via the dual-action gate valve gear mechanism with two spring assemblies.
Features
- Chemically nickel-plated steel housing
- High axial and horizontal rigidity
- Exact positioning, high dynamics, powerful drive and long service life through the use of high-precision linear screw drives
- Higher holding force due to the air-plus port
- Can be used on all SNS roller guide rails
- 5 million clamping cycles (B10d value) – the B10d value is not attained with the PLUS connection
Product description
Functional principle
Air pressure: 0 bar
Clamps with spring force
In the event of a pressure drop, the MKS clamps 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.
Air pressure: 5.5 - 8 bar
Decompression with air pressure
The clamping profiles are held apart by the compressed air.
- Free movement is possible
