A pressed steel pulley and a Fafnir precision ball bearing with rubber seals are combined to make a complete economical self-contained unit. The rubber "tire" cushions the chain preventing undue wear on the pulley surface or chain. The ball bearing is a Fafnir single row radial type with inner ring extended on both sides to provide clearance for abutting parts and greater support on the shaft. The contact type Fafnir rubber seals assure positive retention of lubricant and full protection against dirt, dust or foreign matter. Special features of the Fafnir Idler Pulley Units are the smoothly rolled-over edges which eliminate belt chafing and scuffing, and the thru "weep holes" on the rivet circle which allow water drainage when the pulley is mounted in a horizontal position. Length 4 inches
