BLACK ACE® SNUGULATOR® APPLICATIONS:

  • Roller chains
  • Locations on the drive system:
    • Low tension requirements
    • Used on load side of drive with slight deflection to eliminate chain whipping
    • Makes grooves into the rubber to act like a rolling shock absorber, giving the chain a cushion for a quiet and gentle ride.
