K20 Series

K20 pneumatic rolling motor is designed for the fast and accurate torque controlled rolling of tubes from 1/4" - 1/2" OD (6.3 - 12.7 mm 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. In line version is available on request.

Push&Pull K50 Series

K50 series pneumatic motors has been specifically engineered to ensure uniform tube to tube sheet expansions, thereby preventing the under and over rolling of tubes. This pneumatic tool features an aluminum body, weighing in at only 10.5 Ibs (4.76 kg) with an ergonomically correct push/pull throttle. Automatically stops tube expansion at defined settings.

AK50 Automatic Rolling Motor

AK50 tube rolling motor with automatic reverse. The machine automatically:

• start up when the expander is located in the tube;
• reverse the revolution to the left once determine the set up torque;
• stop when expender is withdrawn from the tube
• thanks to delay timer, machine automatically runs in forward direction after defined period from end of previous expansion ("NS" option)
• automatic tube expander lubrication ("L" option)

All the other features are the same as for standard K50 rolling motors.

K60 Series

K60 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.

• Strong, lightweight aluminum
• housings for easier handling and less operator fatigue
• Rugged drive combines precision control and measured torque output
• Simple dial-a-torque adjustment collar for easy set up
• Cushioned shut-off reduces torque reaction
• Quick change chucks to improve productivity

AK60NS Automatic Rolling Motor

AK60NS is a tube rolling motor with the fully automatic reverse system. The machine automatically:

• startup rotating in the forward direction;
• reverse the revolution to the left once determine the setup torque;
• thanks to adjustable delay timer, the machine automatically runs in forwarding direction after a defined period from the end of a previous expansion;
• automatic tube expander lubrication "L' is available optionally.

All the other features are the same as for standard K60 rolling motors.
