Technical Data  Sprockets for Large Size Conveyor Chains  Handling

7. Limits of Conveyor Chain Use

As usage limits for each component of the conveyor chain are noted below, check the degree of wear of each component on a regular basis.

These usage limits are values determined based on the performance of the conveyor chain itself. If there is a usage limit for the conveyor body, use this as the base value.

Replace the chain and sprockets at the same time.

7.1 Part Usage Limit

7.1.7 Wear on Sprocket Teeth Face or Sides

Worn sprocket teeth may accelerate chain wear during engagement. Regularly inspect both sprockets and chains.

  • 1) Wear limits for sprocket teeth surfaces are roughly shown in the figure below.

  • 2) Tsubaki recommends replacing the sprocket when teeth are worn. Avoid flipping the sprocket over and continuing to use sprockets with worn teeth bottoms.
