Made of very strong steel that machines to a smooth finish.
PPI conveyor pulley shafting are a vital part of the total pulley assembly. Standard PPI shafting is AISI 1045. The higher carbon content in AISI 1045 results in a very strong steel that machines to a smooth finish. Normally, PPI uses T&P for shafting up through 5-15/16”. While, hot rolled and or forged shafting (depending upon size, availability and specifications) is used above a 6” diameter.
