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.
