Drum Pulleys

It is a single drum pulley line that can be used everywhere from the everyday light aggregate conveyor to the toughest Quarry Duty application. You no longer have to guess which pulley you need because the Pro Duty covers them all!

Wing Pulleys

Individual, all steel wings and gussets expel excessive build up of material and provide cleaning action.

Hubs and Bushings

PPI offers entire pulley assembly solutions. Look at our options for bushings, lagging and shafting to make installation simple.

Shafting

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.

Idlers

PPI's full line of idlers meet or exceed CEMA requirements for load, life and dimensions. They are designed and manufactured for long trouble free life with no greasing.

Single Disk Pulleys

A continuous weld of the disc to the rim, coupled with heavy duty construction and a high compression hub and bushing. PPI's Single Disc Elevator Pulleys provide a one-piece, all steel, single disc pulley that is capable of reducing stress and deflection.
