Packaged Stationary Field Clutches (SFP) - 1

Shaft Mounted Clutches Warner Electric’s packaged stationary field clutches are factory assembled and burnished to deliver the maximum rated torque immediately. In addition, a packaged product assures that all engineering factors regarding the proper alignment of components to one another have been established at the factory. This allows the unit to be ‘slid on the shaft’ after being shipped to you. The proper alignment of components is critical to achieving maximum torque and assuring long life. Features • No assembly required • Anti-backlash armatures standard • Ball bearing mounted field and armature hub • Four sizes available Size 180 – 15 in. lbs. Size 250 – 70 in. lbs. Size 325 – 125 in. lbs. Size 400 – 270 in. lbs. Besides saving valuable assembly and run-in time, the SFP clutches incorporate an original Warner Electric concept. The concept of the stationary field eliminates the need for brushes. Brushes can be a high maintenance item in an electromagnetic clutch because of the mechanical friction seen at the collector ring. There is no mechanical friction with the stationary field design. In sum, all of the best possible features wrapped up into one compact package - Warner Electric’s SFP. • Packaging equipment • Controlled, soft starts • Film readers • Speed variation • High cycling • Medical equipment • Sorting/feeding equipment
