Pneumatic Rolling Motor K20 PNEUMATIC ROLLING MOTORSK20 pneumatic rolling motor is designed for the fast and accurate torque controlled rolling of tubes from 1/4” – 1/2” OD (6.3mm – 12.7mm OD). This uniquely designed tool with automatic reverse, expands tubes to a preset torque, at which point it automatically trips over to its reverse rotation, backing itself out of the tube ready for the next expansion.The process is fast and effortless making it the ideal tool for production rolling applications. Our K-20 Models are available in 500, 1800 & 2500 rpm’s (see chart for suggested Tube Diameters). All models are furnished with their own carrying case & instruction manual.MotorsMOTORFREE SPEEDMINIMUM TORQUEMAXIMUM TORQUEWEIGHTLENGTHAIR CONSUMPTIONTUBE CAPACITY ODCHUCKSCHUCKS OPTRPMft.lbsNmft.lbsNmLbsKginchmmcfml/mininchmminchmminchmmK20-5505500,1660,2266,258,472,641,28,62219174801/212,71/4”6,353/89,5K20-180018000,1660,2262,253,052,421,18,07205174803/89,51/4”6,353/89,5K20-250025000,1660,2260,660,92,291,18,072051,74801/46,31/4”6,353/89,5READ DETAILED SPECIFICATIONK60 PNEUMATIC ROLLING MOTORK60 rolling motors control expansion by the accurate measurement of torque. They automatically stop expanding according to a predetermined setting. Torque control prevents over- and under- expansion of tubes, assures uniformly tightened tube joints, and provides maximum holding strength for individual tubes. All K60 motors include torque sensing cams designed and manufactured specifically for tube expanding applications.KEY FEATURESStrong, lightweight aluminum housings for easier handling and less operator fatigueRugged drive combines precision control and measured torque outputSimple dial-a-torque adjustment collar for easy set upCushioned shut-off reduces torque reactionQuick change chucks to improve productivityTOOL IN ACTIONMotorsMOTORFREE SPEEDMINIMUM TORQUEMAXIMUM TORQUEWEIGHTLENGTHAIR CONSUMPTIONTUBE CAPACITY O.D.*SQUARE SIZECHUCKS OPTOPERATING HOSERPMFT.
