ABSTRACT
This article focuses on a one-piece pulley. This idler pulley for outdoor power equipment is spin-formed from a single-piece steel blank. Conventional pulleys are usually made up of two stamped metal halves. When assembled they "sandwich" a bearing in between before welding or riveting secures the halves. Due to variances in the stampings or positioning of the bearing, such trapping may not align the bearing axis precisely with that of the pulley. The cost of the one-piece pulley is comparable to traditional pulleys.
