The ball bearing pilot clutch is generally recommended. Mach III has a variety of ball bearing pilot clutches to choose from: regular duty end of shaft mount, regular duty through shaft mount, heavy duty end of shaft mount and heavy duty through shaft mount. Bronze bushing pilot clutches are only appropriate in cases where the speed of the clutch is under 200 RPM and the sprocket or pulley that must be mounted on the pilot is too small for the ball bearing pilot version. Mach III offers bronze bushing pilot clutches in both end of shaft mount and through shaft mount styles.
Whether using a bronze bushing or ball bearing pilot clutch, properly attaching the pulley or sprocket to the pilot is important if the clutch is to function and wear correctly. Click here to view Mach III’s eBook on this topic.
