Dodge HE bushings were designed specifically for conveyor pulley applications. The HE bushing has unique features and a “high endurance” design that is available only from Dodge.
14° self-locking taper angle clamps to the shaft faster than any other keyed compression-type bushing
Full-length split taper for increased shaft locking power
Grade 8 bolts on HE60 and larger sizes for high performance in demanding applications
Thicker mounting flanges for increased mounting force
High Strength with Low Installation Stress
The Dodge HE bushing system’s 14 degree taper angle results in the lowest amount of end disc deflection of any tapered bushing system available. This prevents pre-loading stress in welds and significantly extends pulley weld life.
In addition, the HE bushing’s Grade 5 or Grade 8 mounting bolts, when properly installed, experience lower installation stress than competitive bushing bolts. This results in less bolt fractures under cyclical loading.
