Timken® Fafnir® 012 8012S Round Bore Standard Duty Wide Inner Ring Roller Chain Idler Sprocket, 0.75 in Dia Bore, 4.332 in Dia Outside, #80 Chain, 12 Teeth, Sintered Steel
A pressed-steel pulley and a Timken® precision ball bearing with rubber seals are combined to make a self contained unit. Two pulley designs are available. One for V-belts and another for the backs of V-belts. A chain idler, identical in construction to the flat idler, is available, with the addition of an assembled rubber tire (part number A-10927). The rubber tire cushions the chain, preventing undue wear on the pulley surface or chain.
