KTR-SI FRA idle-rotation overload couplings

The KTR-SI FRA is a idle rotation overload 联轴器 with automatic re-engagement that reliably uncouples the drive train in the event of overload, thus protecting against expensive damage. Due to its low-backlash, positive-locking ball engagement 系统, it separates the driving and driven side in a lightning speed. After eliminating the overload the KTR-SI FRA can automatically be re-engaged by reversing the direction of rotation at low speed. This feature makes them ideal for hard-to-access mounting situations and use in harsh conditions. With an adjustable overload range of up to 3,000 Nm, the KTR-SI FRA is suitable for a wide range of industrial applications: The KTR-SI FRA idle rotation and automatically re-engaging 过载联轴器 are available as a flange type FT or in combination with our 弹性 ROTEX 联轴器 (轴-to-轴 connection).
