Heavy duty and extra drum conveyor pulleys deliver high performance and are available when you need them. Available from stock in many common sizes, or custom made, Heavy-duty drum conveyor pulleys meet and/or exceed CEMA (Conveyor Equipment Manufacturers Association) application standards for use with conveyor belts rated up to 750 PIW (Pounds per Inch of Belt Width) / 131 kN/m.
Features
• Heavy duty one-piece rim construction with submerged arc weldments
• Shaft attachment options available in XT or HE
• Available from stock with taper-compression hubs
• A variety of lagging options including standard stock SBR rubber, D-LAG natural rubber, and made-to-order vulcanized ceramic lagging
• Meets or exceeds CEMA dimensions Common industries:
• Mining
• Unit & Baggage Handling
• Paper & Forest
• Power Generation

Belt Conveyor pulleys offers two standard designs that are stocked for quick delivery, CEMA duty (Conveyor Equipment Manufacturers Association), HE (High Endurance) welded hub and Extra HE integral hub construction. These are available with a plain surface and rubber lagged. HE bushings with the 14-degree taper and 3/8 inch 60 Durometer SBR rubber, with herringbone groove lagging, are standard, stocked features. recommends pulley designs within the four classes of service detailed below. All of our designs strive for a balance between cost and reliability. When possible, welds are avoided or eliminated to maintain the full strength of the base metal. Our welded designs rely upon the chemistry of the base metal, the type of weld, and the geometry of the structure to achieve optimum post-weld performance as explained below. WARRANTY • Class IV and III conveyor pulleys are conditionally warranted against defects in material and workmanship for one year of operation. A two-year warranty is available when loading information is provided. Note: Special Construction features listed at the bottom of page PT15-6 can be added to both Class IV and III conveyor pulleys to extend service life. Because these conveyor pulleys are made to order, they will require a longer lead time for shipment. The Special Construction modifications must be quoted at the time of inquiry and before order entry. • Class II and I conveyor pulleys are conditionally warranted against defects in material and workmanship for two years of operation because loading information must be provided. CLASS IV Heavy Duty CEMA Standard drum conveyor pulleys use 14-degree taper welded hubs and bushings with special consideration for post-weld strength with submerged arc welds. These conveyor pulleys meet or exceed all requirements for steel drum conveyor pulleys established by CEMA, and as detailed in ANSI standard number B105.1. The standard establishes load ratings and dimensions for use with fabric belts rated to 800 PIW (Pounds per Inch of Belt Width). CLASS III Mine Duty Extra conveyor pulleys use a proprietary 14 degree (taper) one-piece integral hub to accept HE bushings. This eliminates the two welds of the hub into the end disc and delivers 100% of the capacity of the end disc steel. There is not a universal standard published for this class of service. The MDX design gives much higher safety factors than conveyor pulleys designed to meet the CEMA load ratings while fitting into the CEMA dimensions. CLASS II Engineered conveyor pulleys utilize one-piece integral end discs and either HE 14 degree taper compression bushings or keyless locking devices. They are designed specifically to meet customer-supplied load and tension ratings. This class is for fabric or steel cable conveyor belts rated at 2,499 PIW. These conveyor pulleys incorporate machined rims and lagging, static balance, stress-relieving, magnetic particle, and/or ultrasonic weld testing. CLASS, I Engineered conveyor pulleys with one piece “T” section machined end discs are continuously butt-welded to the pulley rim for fabric or steel cable belts rated over 2,500 PIW up to the maximum available from belt manufacturers, currently in excess of 10,000 PIW. These conveyor pulleys use keyless locking devices for shafts up to 30” in diameter. These conveyor pulleys incorporate machined rims and lagging, static balance, stress-relieving, magnetic particle, and/or ultrasonic weld testing.
