Full Range Of Rolling Motors



MultipleExpand AP-S2



Two spindle, air driven torque control tube expansion system with adjustable tube pitch. Designed for all type of coolers that suit to the motor torque capacity. One air lever valve activates all motors and the whole expanding process goes automatically and independently on every motor.

  • Up to twice performance
  • 2 spindles working simultaneously but independently
  • Working range covers tubes from 1/4” up to 1/2” (5/8”*)
  • Adjustable tube pitch 51 – 90 mm (2”- 3,54”)
  • Spindle with reverse compensation feature in case of non simultaneous return
  • Precise torque control tube rolling with automatic reverse
  • Commonality of parts with other K20 rolling motors.

* varies depending on tube material , gauge and tube sheet thickness

The L20 rolling motors is based on K20 rolling motors and the all parts are interchangeable.

AK60 Full Automatic Rolling Motor

Key Features :

AK60 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  • stop when expender is withdrawn from thetube.

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

AK60 Full Automatic Rolling Motor

K60 Pneumatic Rolling Motor

Key Features :

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

K20 Pneumatic Rolling Motors

Key Features :

K20 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.
