Steel construction belts from National Element are especially adaptable to conveying heavy, rough or sharp material. An assembled belt consists of hinged links, side wings, tubes, thru pins and dual strands of roller chain. The hinged links are assembled in horizontal rows by passing the tube through the hinges. The thru pins are inserted into the tube and fastened into the side chains thus supporting the links and causing the chain to take all the tension. Bushings Steel bushings = 15-18% coefficient of friction Nylatron bearings = 10-13% coefficient of friction Roller bearings= 4-5% coefficient of friction Steel Links Standard plain steel links precision welded in widths of : 24″ ( 18” thick flat top and piano hinge plate belts) 6″ (316” belt) 12” (¼ belt) Hinges Hinges formed in 1-12″ – 3″ increments on the link to allow special belt widths of the same 1-12″ increment. Side wings Side wings interlocked and afford continuous overlapping through bends and over the sprockets. Mig welding to the belt prevents thin pieces of material from getting under the wing. Standard sizes: 18″ thick x 1-12″ for 2-12″ pitch 18″ thick x 2-12″ for 4″ pitch 316″ thick x 3″ or 4″ for 6″ pitch 316″ thick x 4″ or 6″ for 9″ pitch Tubes The tubes are .760″ I.D. x .970″ O.D. steel running through the hinges for the complete belt width and rotates on the thru pin for a better bearing area. Maintenance is easy because it is not necessary to disconnect the belt at a hinge point to remove a pin. It is the tube that holds the belt together. Pins 12″ dia. thru pin with milled ends and 532″ “S” pin 34″ dia. pin with milled ends and 14″ cotter pin heavy-duty belt pin with milled and threaded ends and 34″ lock nut 34″ dia. split pins for easy maintenance in tight spaces Pin, tube and hinge provides a 1-12″ thick heavy-duty joint
