Conveyor Belts

Conveyor belts come in many different plies, covers, colors, surfaces, and coatings.

Belt samples are available! Contact us for details.

There are many abbreviations used when referring to conveyor belts:

o AS = Anti-Static
o C = Cover
o COS = Cover One Side
o C-P = Cotton/Polyester Blend
o CR = Cross Ridge
o FBS = Friction Both Sides
o FI = Fabric Impression
o FS = Friction Surface

o HD = Heavy Duty
o MOR = Moderate Oil Resistant
o MSK = Mini Skim Coat
o PIW = (Per Inch Width) area – 1 inch wide x 1 foot long
o SB = Slider Bed
o SC = Static Conductive
o SOR = Super Oil Resistant

Heavy Duty Conveyor & Elevator Belts:

– available from 2 to 4 ply, thicknesses up to ¼”, with options including high heat resistant, and oil resistant

Other options for conveyor belts include:

  • Splicing Options – (Vulcanized, endless, finger spliced, longitudinal)
  • Mechanical Fasteners – (Alligator lacing, clipper lacing, spiral lacing)
  • Flanges – (Molded, siped, notched, drilled)
  • V-Guides
  • Hole punched & perforated Cleated_Belt
  • Grooving Thick_Belt
  • Notching Clipper_Lacing
  • Urethane Cleats
  • Magnetic separators

Conveyor Belt Calculations:


1. Required horsepower (HP) to drive a belt conveyor:

For level conveyors:

HP = Coefficient of Friction x Speed (FPM) x (Product Weight in lbs + Belt Weight in lbs)

 For incline conveyors:

HP = (Product Weight x Sine of Angle) + (Product Weight + Belt Weight) x Friction x Speed

Coefficient of Friction:

  • Slider Bed .30
  • Belt over Roller .05
  • Belt Driven Roller .10
  • Chain Driven Roller .075
  • Slat Conveyor .15

2. Belt weight:

        BW = .375 lbs per square foot per 1/16” thickness

3. Feet Per Roll of Belting:

         Feet = Outside Diameter of Roll (inches) – Core Diameter of Roll (inches)
15.3 x Belt Thickness (inches)
