Plastic Roller Table ST  Major Specifications

ST-NP

Features

  • Conveyed goods can be placed directly on rollers without the use of pallets.
  • This type has special attachments that are level with the plastic rollers, enabling conveyed goods to move smoothly from one side to the other across two parallel strands of chain.
  • Coeffi cient of rolling friction for rollers is from 0.06 to 0.10.
  • Gap between plastic rollers does not change even when bending because rollers are mounted above the pitch line of the base chain.
