Extreme-force electric actuator

Auto sales finally got back above pre-recession levels in 2014 with August sales reaching a seven-year high. After six long years, sales levels have matched 2007’s pace. More importantly, several research groups expect 2015 continue to grow. Today’s Motor Vehicles allows marketers direct access to this healthy industry with continued growth.

Tolomatic’s expanded extreme-force electric actuator family now includes the RSX128 actuator, rated up to 50,000 lb-f (222.4kN). Designed for 100% duty cycle and to replace hydraulic cylinders, the RSX actuator features Tolomatic’s precision-ground planetary roller screws for operating life in challenging environments. Applications include assembly, metal fabrication (pressing, punching, clamping), automotive manufacturing, timber processing, motion simulators and more.

The RSX128 actuator represents a 60% increase in the bi-directional maximum force provided by Tolomatic’s extreme-force RSX electric actuator family. Additional frame sizes include the RSX080, which provides 18,000 lb-f (80 kN), and the RSX096P press-model, optimized to provide extend force up to 40,000 lb-f (178kN).

For all models, IP65 is standard for protection against dust and water spray. IP67 is optional for improved resistance of water ingress. A modified food-grade version, designed for volumetric filling and other high-force food-and-beverage applications, is available as a custom design with food-grade white epoxy coating and stainless-steel components to meet the requirements of washdown applications.

The entire RSX actuator family’s construction includes tie-rods and Type III hard-coat anodized aluminum housings. A standard internal anti-rotate feature prevents the rod from rotating without external guidance.
