Chain Driven Roller Conveyors

Chain Driven Live Roller Conveyors are used for transporting drums, pallets, engines, racks, coils, solar panels, glass, foam boards, tires, rotors and many other light or heavy items. Our CDLR’s are built using heavy duty welded and painted construction. Our welded sprockets are machined and hardened providing positive driving force to the product. Our widths and lengths are determined according to your specific requirements.

Roller Capacities for CDLR Conveyor

Roller capacity refers to the maximum load a single roller can support. There are several factors in establishing a roller’s true carrying capacity and they include but not limited to the following:

  • Load configuration, stability
  • Bearing capacity
  • Bearing offset (distance from side frame to centerline of balls)
  • Axle deflection
  • Tube deflection
Roller capacities are based on tube deflection of no more than .20% of BF and axle angular deflection of no more than 1 degree at the bearings. Angular deflection of axle at the bearing is limited to .82 degree for semi-precision bearings. Since conveying surfaces are not perfectly flat, use 2/3 of the rollers under the product when calculating the required roll capacity. Common practice shows that it is not practical to use 1” diameter rollers on 1 Ό” centers for a 5000 lb. product (10” x 100” long), therefore, we use the following guide lines:

Roller Diameter & Axle Maximum Product Weight
1.9” Dia – 7/16” Hex 2000 lbs.
2 ½” Dia – 11/16” Hex 4000 lbs.
3 ½” Dia – 1-1/16” Hex 8000 lbs.
3 ½” Dia – 1-7/16” Hex 15,000 lbs
4” Dia – 1- 7/16” Round 20,000 lbs
5” Dia – 1-11/16” Round 40,000 lbs.


It is critical that shock loading is addressed as a separate issue; our experienced application engineers can guide you thru this process. All above capacities and guidelines assume zero shock loads. Capacities are applicable for single or dual lane applications only.
