S type rubber calender is mainly used to Roll-extrusion for rubber sheet, conveyor belt. Sticking & friction rubber of fabrics. The rolls are made of chilled alloy cast iron with bored cavities and can be heated by steam or cooled by water homogenously to meet different requirements. The machine is consisted of bedplate, frame, rolls , motor , coupling ,speed ratio gear , adjusting spacing device , the adjusting temperature device of roll . The bedplate is whole model, Installation convenience. Roll are made of chilled case alloy iron, the working surface of roll is hardness and smoothly. steam and cooling water can pass through inner of the rolls so that surface temperature can be adjusted . Roll fluctuation arrange , under roll is initiative roll , motor pass through coupling ,To make under roll driving , above roll by under roll pass though speed radio driving . Roll bearing adopt roll bearing, high precision, long service life , Axes pathway is no abrasion . Adjusting spacing device is consisted of one left and one right hand wheel. The bearing bases need is moved and reached nip by worm and worm wheel.
