Torq/Gard Overload Clutch Sizing and Specs


  • Torque (in-lb) = Horsepower (hp) x 63025 / RPM
  • Horsepower (hp) = Torque (in-lbs) x RPM / 63025
  • Tripping Torque (in-lbs) = Operating Torque x Service Factor

General Torq/Gard Information

Torq/Gard overload clutches are one of the most popular torque overload devices for power transmission applications. A spring loaded cam follower seated in a single hub cam detent cause the hub and clutch to rotate together. Therefore, the clutch always resets in the same position if tripped, staying in phase. They can be turned in both directions by design. After tripping, the unit automatically resets when it returns to the set position, usually by jogging the machine after the jam or overload is cleared. Shaft bushings are used to accommodate a standard maximum bore unit to the application shaft requirement. Torque capacity up to 8000 in-lbs, and speed ranges from 350 - 900 rpm.

  • Help protect the entire drive train of your machinery from damage due to excessive torque generated by overloads and jamming.
  • Instant reaction and automatic reset by "jogging" the machine provides unsurpassed protection and minimizes down-time.
  • Disengages at the pre-set torque limit.
  • Precise overload protection with an elegant yet rugged cam-in-detent system.
  • Detector plates, coupling options and other accessories enhance design flexibility.
  • Sealed for Life Gasket and O-ring sealed body, packed with high-performance, moisture resistant, lithium based grease for outdoor and wash-down application.
  • International-Orange Finish is a durable bright orange enamel finish for high visibility and easy identification of rotating components.

Torq/Gard Application Considerations

The Torq/Gard should be used on the low speed side of a speed reducer in several ways:
  • Direct Drive: The Torq/Gard can be mounting on the speed reducer output (low speed) shaft and directly connected to the driven machine using an Ever-Flex half coupling and the Universal Adapter Plate.
  • Chain Drive – Mounted on Speed Reducer Output: Mounting the Torq/Gard on the output of the gear motor or speed reducer with a roller chain connection to the driven machine provides the most economical clutch assembly. The Torq/Gard is designed to protect the weakest link in the drive system.
  • Chain Drive – Mounted on Driven Machine: Mounting the Torq/Gard on the driven machine and powered through a chain and sprocket drive tends to absorb peak starting torques. 
  • The Torq/Gard should never be used on the high speed side of a reducer. Clutch sensitivity becomes a function of the reducer’s gear ratio. As an example, when used with a 100:1 reducer, a 100 in-lb torque variation on the output side of the reducer will reflect only a 1 in-lb change on the input side. Do not exceed the maximum RPM shown in the Torq/Gard selection tables.
