Large Size Conveyor Chain for Heavy Loads (Bearing Roller Conveyor Chain)

Bearing Roller Conveyor Chain has a unique structure with cylindrical bearings inside rollers for less running resistance/much higher roller allowable load/improved bush-roller wear life, thereby realizing ”higher efficiency", "cost reduction", "suppression of stick-slip phenomenon*” and "longer life of rollers/rails", which were difficult to solve with conventional conveyor chains.

In addition to Standard series, the range includes Anti-dust series, Lube-free series and Water resistant lube-free series, which can be selected to suit the required application.

*Phenomenon in which a chain repeatedly starts and stops, despite there being continuous drive from a drive source.

Screw Lock Link, a convenient connecting link that requires just a torque wrench to complete the cut and connection, is also available. Click here for details

1. Bearing Roller structure

Bearing Roller structure

2. Bearing roller functions

  • ・Reduces chain's running resistance (1/3 of general use chain )
  • ・Greatly increases allowable load of rollers

3. Bearing roller effects

  • ・Less chain tension and required motor kW
  • ・Stops stick-slip phenomenon on long conveyors or at low speed operation
  • ・Suppresses poor roller rotation problems and decreases rail wear
  • ・Improved wear life (Between bushes and rollers )
  • ・Reduction in CO2 emissions and electricity costs
