Product Information

Bushingless hollow pin roller chains are constructed on the same principle as Galle chains, i.e. the connecting rod bearings are located between the pins and outer plates, resulting in an extremely small bearing area. This provides the advantages of high breaking strength and a hollow pin with a large inner diameter.

Product Highlights

  • Available based on the same chains manufactured to ISO 606 or as special chains
  • All ELITE chain plates are manufactured using processes such as fine blanking and ball-drifting, so a particularly high contact ratio is guaranteed
  • Solid, case-hardened rollers with good wear resistance
  • In general, hollow pins made of seamless precision steel tubes for improved precision and wear resistance
  • Many of these chains are supplied pair-matched to ensure exact parallel running, one of the main requirements that these chains must fulfill


  • Conveyor technology
  • Food processing industry
  • Measurement and testing technology
  • Feeding and automation technology
