Bessey Structural Clamp SGM 400/140 max. clamping force 35,000 N Ever higher clamping forces with ever greater clamping depths and spans. The STBS structural clamp - very robust and durable, maximum clamping forces. Faster working thanks to an optimized profile 20% more clamping force per spindle revolution. The optimized profile shape guarantees greater clamping force build-up in a shorter time with greater stability and safety. The fixed jaw and pressure plate are manufactured in one piece, tempered and therefore highly resilient. The heat-resistant, easily interchangeable pressure plate with a large ball head on the inside can be swiveled up to 35°. Special features 3.17 kg clamping depth b 140 mm guide profile thickness 13 mm clamping range a 400 mm guide profile width 34 mm packaging unit 1 piece
