RS roller chain BS/DIN standard

  • High-precision solid bushes and special lube dimple processing improve lubrication retention effects and more than doubled the wear life.
  • RC (ring coin) processing, in which a ring-shaped groove is provided around the plate hole, prevents strength reduction caused by clearance necessary for connecting and disconnecting. This achieved the same strength as the chain itself.
  • Newly developed specially-shaped pins and new riveting style deliver easy cutting and connection without using a grinder.
