Special models can be manufactured to meet requirements including the desired stroke and the ram chair diameter (ϕ A) that prevents contact with adjacent nuts.● An S-1R coupler is attached. ■BS1.35-5GModelMaximum operating pressureMaximum outputEffective areaStrokeMaximum bolt diameter Maximum nut dimensionRequired oil volumeApprox. weightϕ Aϕ BMinimum overall length (C) Coupler connection port sizeAttached couplerMPakN135cm219.32mmϕ mm24Hex (NAF)/Round (OD)36 x 41.646 x 53.1cm310kg5.5mm75mm80mm172BS1.35-5GBS2.6-8GBS4.4-10GBS5.7-10GBS8.7-10GBS11-10GBS16-10GBS22-10G26044037.6864.210304265 x 7575 x 86.685 x 98.195 x 109.7110 x 127130 x 150316512.519.095125120146220224Bolt tensionerModel code structureS:Spring-return type D:Double-acting type R:Load-return type 70570870111082.46125.07159.431010104856648312516022.529.045.0135147160156180215235250260Rc3/8S-1R■Example of useCylinder output135kN1.35:260kN2.6:440kN4.4:5.7:570kN8.7:870kN11:1100kN16:1600kN22:2200kNStroke (mm) 16002200233.1317.31010769023431865.078.0185220250285278290G:Nut tightening systemL:Nut tightening systemwith bevel gearwith insertion barBolt TensionersBolt Tensioners * Please specify the dimensions of the bolts and nuts to be used when ordering. * If one bolt tensioner is used to tighten bolts different in size, tension bars compatible with individual bolts are required. ■BS5.7-10GMake-to-order product 192BS1.35-5G
