Roller Screw Actuator

Dec. 1, 2010

 Nook Industries has recently introduced the Infinity 1 Roller Screw Actuator that was tested to over 1,000,000+ cycles of continuous duty (49 million inches of travel) at 2500 lbs of thrust and at a travel rate of 10 in/second. A cost-effective alternative to hydraulics, the high-performance, heavy-duty electromechanical actuator offers long life with high dynamic and static load capacity.

Designed for a myriad of heavy-duty industrial market applications (including welding, food, packaging, etc.) requiring precision speed and load control, Infinity 1 also delivers an essential IP (International Protection) rating of IP64+ through a possible IP68 (motor dependent). Design elements contributing to this high IP rating include; a hermetically sealed case and enclosed Integrated Position Transducer, and Integrated Load and Torque Sensor.

The Infinity 1’s Integrated Position Transducer offers high precision absolute position measurement (in Analog and SSI output) and delivers 1.7x greater position accuracy than using a motor encoder. The Integrated Load and Torque Sensor offer absolute load measurement (in Analog mV output) with no translating wires.

Roller Screw Assembly: High performance metal treatment process, (4) rugged anti-rotation slider blocks.
Precision Mounting: Enables quick installation and drop-in replacement of hydraulic actuators.
Mount Any Motor: Incorporates standard Motor Configurations NEMA and IEC (brake, encoder, resolver), Liquid cooled motors, custom motors (size dependent).
Individually Machined No adapter plates, machined from a single block of aluminum for added strength/stiffness
Pulley Housing: 1:1 and 2:1 drive ratios, custom ratios available.
