Airflex offers several economical packaged ap-
plications utilizing CB elements. Figure 5 illus-
trates an Airflex sheave clutch, incorporating a
built in rotorseal and sealed ball bearings. A
wide range of sheave sizes can be used with
this type of package.

Figure 6 illustrates a typical engine-mounted
application, where the clutch element is at-
tached to a spider and the drum is attached to
a shaft-mounted flywheel or bullgear. This
type of application is typically used when drill-
ing of the air passage in the driving shaft is nei-
ther possible nor practical.

Figure 7 illustrates a CB clutch mounting for
punch press applications. The drum and drum
hub are attached to the crankshaft or back-
shaft and the element is attached to a bearing-
mounted flywheel or bullgear. CB clutches on
punch presses are typically used in combina-
tion with Airflex type CTE or CS brakes.
2.1.7
Airflex can provide specific drawings covering
the different mounting arrangements men-
tioned. The maintenance of the element as-
sembly, tolerances and wear limits of friction
material, and alignment specifications in this
manual apply to all CB applications.
