Magnetically Applied Clutches

Operation (click to enlarge) RFTC Disengaged
Description

This rotating field tooth clutch is designed to operate both dry and in oil. No bearings are used. Current is supplied to the magnet body coil through an electrical brush and slip ring. (Grounding is accomplished internally through the magnet body to the machine shaft.) Many options are available.

Specifications
  • 3.1″ to 9.7″ diameter; 1.4″ to 4.75” length
  • Bore sizes from 0.8″ to 2.7″
  • Static torque from 40 to 5200 lb-ft
  • 2500 to 89000 RPM max speed
  • Operates both dry and in oil
  • Modified designs and customized assemblies available

Description

Stationary Field Tooth Clutches operate both dry and in oil. Sealed bearings are permanently lubricated eliminating the need for grease fittings and maintenance.

Specifications
  • 3 to 10.5” diameter; 2 to 7.5” length
  • Bore sizes from 0.5 to 4.25”
  • Static torque from 40 to 5200 lb-ft
  • 1400 to 3500 RPM
  • Operates both dry and in oil
  • Modified designs and customized assemblies available
Operation (click to enlarge) STCC Disengaged
Description

Stationary Field Tooth Clutch Couplings integrate an SFTC clutch with a factory aligned sleeve and output hub for a prefabricated “mount and run” solution. The STCC design dramatically simplifies application design complexity and reduces installation time.

Specifications
  • 4.5″ to 10.6″ diameter; 3.8″ to 8.6” length
  • Bore sizes from 0.8″ to 2.9″
  • Static torque from 160 to 5200 lb-ft
  • 2500 to 5200 RPM max speed
  • Operates both dry and in oil
  • Modified designs and customized assemblies available

Description

Wall Mount Tooth Clutches are a stationary field design with comparable performance to SFTC models, except they eliminate the use of bearings — making them ideally suited for high speed applications above 3600 RPM.

Specifications
  • 3 to 10.5” diameter; 2 to 6.25” length
  • Bore sizes from 0.5 to 4.25”
  • Static torque from 40 to 5200 lb-ft
  • 2500 to 8000 RPM max speed
  • Operates both dry and in oil
  • Modified designs and customized assemblies available

  • Wet Starting Torque – 6 to 408 lb-ft
  • Dry Static Torque – 12 to 802 lb-ft
  • Dry Starting Torque – 9 to 612 lb-ft
  • Max Speed – 1750 to 4200 rpm
  • Nine standard frame sizes
  • Overall Length – 2.6″ to 5.4″
  • Overall Dia. – 3.9″ to 9.2″
  • Rotor Bore – .8″ to 2.8″
