You need Adjustable Idler Sprockets to:
  • Obtain proper chain tension when neither driving nor driven shaft is adjustable, and to take up slack chain developed through normal chain wear
  • Guide chain around an obstruction
  • Prevent whipping action in theslackspan of chain transmitting an uneven load
  • Bring about greater chain wrap around a small sprocket, particularly if it is the lower sprocket in a vertical drive
  • Provide for reversed direction of rotation of a sprocket in contact with the outside of the chain.

Idler sprockets should not rotate at greater speeds than are allowable for drive sprockets of the same size. They should be mounted in contact with the slack span of chain. Mount them on the outside of the chain when the arc of chain wrap on the smaller sprocket would otherwise be less than 120°.
It is advisable that idler sprockets have at least three teeth in mesh with the chain. Inside mounted idlers usually account for quieter operation, especially if centers are short and speed is moderately high.
  • Machined steel sprockets
  • Hardened teeth
  • Hardened & ground steel journals
  • Oil-impregnated sintered bronze bushings

NOTE: Idler rpm should not exceed 2500 and radial loading should be less than 50 pounds.
