Industrial Conveyor Belts

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
