Description Very high axial holding forces Dynamic and static stabilization in the axial direction Heavy-duty brake Compact design, compatible with DIN 645 Clamps and brakes with pressure Features Can be used on all SNS Ball Guide Rails Up to 1 million clamping cycles Up to 2,000 emergency braking operations Threaded on both sides for the hydraulic connection Solid, rigid steel housing, chemically nickel-plated High positioning accuracy Release pressure 150 bar Integrated all-around sealing Special pressure diaphragm technology for maximum functional reliability without pressure losses or leakage Brake shoes with integrated positive-locking, large-surface contact profiles for maximum axial rigidity Super heavy-duty model Low displacement 10 million clamping cycles (B10d value) Product description Functional principle Hydraulic pressure: 50 - 150 bar Clamps and brakes with pressure The large-scale clamping profiles are pressed directly by the hydraulic oil onto the flanks of the Ball Guide Rail via a piston principle. Hydraulic pressure: 0 bar Decompression with spring force A pre-tensioned return spring allows for short decompression cycles.

The hydraulic connection is attached on two sides. One connection is suitable for the application. Take care when venting the fixed and flexible hydraulic lines, because air connections can damage the sealing elements. Connection structure, mounting the clamping elements To prevent detrimental effects, e.g. permanent grinding
