Conventional Chain or V-Belt Drive Systems:

By Every Important Measure, It's No Comparison

Unlike conventional drive systems, the new DURA-DRIVE PLUS motorized pulley has no chains or V-belts to tighten or replace, no sprockets to align, clean or lubricate, no bearings to grease, and doesn't require chain guards that need replacing.

It's a simple - yet small and powerful - one-piece motorized pulley that's guaranteed to power your belt conveyor for years without breakdown. All gearing is made of high alloy steel, not plastic. Just an in-place oil change after 20,000 hours is all that's ever needed. No disassembly required.

The result? Almost no maintenance or downtime. And that means lower costs and higher productivity. There's more.

Much more compact...safer, cleaner operation

Unlike bulky conventional drive systems that fit externally on a conveyor, DURA-DRIVE PLUS is actually part of the conveyor and much more compact. That means you can fit more conveyor into less floor or overhead space.

Also, all moving parts are enclosed in the steel pulley shell. That eliminates hazardous moving parts and pinch points, along with the potential for electric shock from water on motors. Also, DURA-DRIVE PLUS is much cleaner because there's no external grease or oil from chains, bearings or couplings. As a result, you improve worker safety and more readily comply with OSHA standards.

What is a motorized pulley?
A motorized pulley is a drum motor in which the body rotates around a stationary shaft. The rotating outer "drum" becomes the traction surface which powers the conveyor belt.

Electric power leads pass through the stationary shaft to motor terminals inside the pulley housing. Since the end shaft does not rotate, there is no need for slip rings to deliver electrical power to the motor windings.

The entire internal mechanism, including the motor, gears and bearings, are completely sealed and protected by the outer metal drum. Oil inside the drum continuously lubricates bearings and gears, and removes heat from motor windings.

Quiet operation

DURA-DRIVE PLUS operates at a very quiet 57-62 decibels, compared to 76-80 decibels for a typical conventional drive. That can help you meet OSHA noise regulations, eliminate the need for costly ear protective devices for workers, and improve your overall work environment.

Simple design means easy specification for new systems,
easy installation for existing ones

Because DURA-DRIVE PLUS is a one-piece pulley and not 10 or more separate components like a conventional drive, it can be easily specified into new systems and dramatically reduce design time. For existing systems, the pulley comes complete with two mounting brackets and hardware. Changeover takes less than an hour per drive.

DURA-DRIVE PLUS...a cost-effective alternative to conventional drive systems

DURA-DRIVE PLUS is priced competitively with conventional systems initially...and it's more energy efficient. For example, a conventional system normally transfers only 60-75% of its mechanical efficiency (horsepower) to the belt. DURA-DRIVE PLUS transfers 95% of its capacity to the belt—a 20-35% increase.

This savings can translate into a reduction of hundreds of dollars in energy costs—per drive, per year. Then when you add in the reduced maintenance costs—per drive, per year—it's easy to see how DURA-DRIVE PLUS motorized pulleys can quickly pay for themselves in a matter of months.
