The Packaged Stationary Field Clutches (SFP) are specifically designed for use in film readers, conveyors, packaging equipment, sorting and feeding equipment, and medical equipment. Units in the series are pre-assembled with precise alignment, meaning that they may be installed directly onto shafts upon delivery. These clutches are also made with a Warner Electric-patented stationary field design that removes the need for brushes in the collector ring. This design eliminates mechanical friction and allows for less maintenance needed.
The SFP features a ball bearing mounted field and standard anti-backlash armatures. The clutches is available in four standard sizes, from size 180 to 400.
