Idler Sprockets

These idlers are the ideal solution when converting fixed centre distance roller chain drives with Poly Chain® GT Carbon™ belts. Idlers can be used to take up extra belt length and provide adjustment for tensioning belt drives.  Idler pulleys and sprockets can alter belt paths and clear obstructions. 


Gates idler sprockets contain sealed ball bearings and an integral shaft for mounting to Gates adjustable idler brackets.  


  • A perfect solution to customising belt drives. 
  • Suited to both Poly Chain® GT Carbon™ and PowerGrip® GT belts.
  • Lubrication and maintenance are not required.
  • 8MGT 12 and 21mm versions available with nickel plating for improved corrosion resistance.
