Timken®
012 8012S

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.
