We make the pulleys to order in standard sizes so the change from smooth pulleys to tracking pulleys is very easy. For most conveyors, all that is needed are two helical tracking pulleys, one at each end. For an existing conveyor, you simply replace the smooth pulleys with the POSITRAC® pulleys. If you order a new conveyor from a vendor, just specify the Dynaloc pulleys at the head and tail positions. The pulleys are made in steel, aluminum and all stainless steel construction.
Positive belt tracking and drive traction eliminate edge fraying of the belt, lagged drive pulleys, and down time for replacing prematurely worn out belting and pulleys. Also, high belt tension is not needed for good tracking, which eliminates excessive belt stretch, lace failures, crown wear, bearing, shaft and end plate failures. Our dual helix tracking/cleaning pulleys are proven to save money on operating and maintenance costs.
Normal lead time is 5-10 working days, FOB our plant here in California. The standard list price includes Taper-Lock hubs and bushings or bored hubs with key ways and set screws. We can also provide bearings, welded in shafts or other types of end fittings.
