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 coupler192
