Note: Initial spring force at 150 bar = 250 daN Order No for spare parts kit: 2480.12.00250 Pressure medium: Nitrogen N2 Max. filling pressure: 150 bar Min. filling pressure: 50 bar Working temperature: 0°C to +80°C Temperature related force increase: ± 0.3%/°C Max. recommended extensions per minute: approx. 80 to 100 (at 20°C) Max. piston speed: 1.6 m/s Fixing: Installation with ring nut(s) 2480.005.00250 can be done with one or two ring nuts. If the hole in the bolster plate is not threaded, two ring nuts are needed. Holes threaded M 38 × 1,5 require one only ring nut for mounting of the gas springs. Mounting with a threaded flange plate has the advantage of a degree of adjustability as far as the flange screws permit, moreover it is often found easier to make do with a clearance hole in the tool plate. Locking is by way of two lock screws with thrust plugs, provided in the threaded flange. Diameter of through-hole in tool plate = 38 mm – plus four tapped holes M 8.
