SERIES

3000 DIMENSIONS

FOR CONTINUOUS OP ERATION, HIGH CAPACITI ES, AND HEAVY, ABRASIVE MATERIALS

Continental series 3000 belt conveyor idlers are for continuous operation , high capacities , and heavy, abrasive materials where lump size is limited by the width of the belt. Troughed belt idlers may be furnished with end rolls inclined at 20°, 35° or 45°, the latter two handling a volume of materials limited only by the construction of the belt.

All idlers are available with 5" or 6" diameter rolls . Flat belt and return belt idlers are available with 5" rolls. All rolls are equipped with precision ball bearings. A separate cartridge type contact and labyrinth grease seal offers triple bearing protection with neoprene contact members, and grease filled clearances.

The counterbored outer shell and stamped end disc are swaged to . perfect concentricity and continuously welded to form an air-tight concentric unit. The stamping cavity is grease-filled before assembly, and its large diameter permits easy movement of grease to the bearings. The efficient grease-in , cartridge seal and the large reservoir of grease make for extended operating life.

The 20 mm diameter through-shafts are machined at both ends, and the bearings are factory adjusted by press fitting the cartridge seal and bearing into the roll end disc.

The inverted angle base has slotted foot­straps that permit easy, quick mounting and alignment. The formed steel brackets are jig­welded to the base to insure roll alignment. The ribbed end brackets are contoured to provide a large clearance so that spilled materials cannot become wedged and stall the rolls .

Series 3000 idlers are available in a wide variety of types including flat belt carrying rubber cushion, training idlers , picking roll an~ variable troughing idlers. Return belt idlers are available in rubber tread , beater and training types . All idlers are available in belt widths to 60 inches.
