Regal Rexnord Corporation has launched a redesigned series of its long-serving, industry-leading Autogard F400 Series torque limiter. This next generation Autogard F400 Series offers significant improvements whilst remaining a drop-in replacement for the legacy 400 Series, matching its predecessor in form, fit and function. 

Autogard torque limiters act as a mechanical circuit breaker to protect a drivetrain, disengaging the driving and driven sides in the event that a jam or overload creates a torque spike that exceeds its preset torque value. The next generation Autogard F400 Series features the best bore size range available, making it compatible with larger drive shafts and allowing customers to select a smaller coupling size based on torque setting. Superior dirt ingress protection is now available as standard, offering minimal, “fit-and-forget” maintenance. In addition, the new design has excellent temperature resistance, enabling customers to use one model for all applications with temperatures ranging from -22°F to 176°F (-30°C to 80°C). 

“The newly redesigned Autogard F400 Series demonstrates the importance that Regal Rexnord places upon continually innovating our technologies,” said Rob Hucker, director of product management. “As well as standardizing previously optional features, we are improving upon the performance and value that we deliver to our customers.”
