R2.1 e-tube - low priced chip protection

Cost-effective, strong e-tubes with 26, 40, 48 and 75mm inner height. Openable and removable lids along inner or outer radius, openable from both sides. Designed to provide a tight seal, with strong double stop-dogs for high fill weights and unsupported lengths.
The video shows how simple it is to assemble Series R2.75 e-chains®

Advantages of the R2.1 system:

  • Large inner height and therefore cost-effective
  • Cables are protected from swarf
  • Easy to fill, lids openable from both sides along the inner or outer radius
  • Low noise operation due to integrated brake
  • Separator notches integrated into the e-tube link and lid for side-mounted applications
