In pulp and paper mills, gearboxes drive the equipment that moves wood, processes pulp, presses water from paper and transports massive rolls through machines that can run hundreds of feet long. Few industries combine continuous operation, massive equipment, extreme loads and harsh environments the way paper mills do. 

Some of the most persistent challenges include:

• 24/7 operation
• Heavy loads from massive rolls and conveyors, with dryer cylinders up to several tons each
• Harsh environmental conditions including high humidity and moisture and contaminants that can degrade lubricants and accelerate gear wear
• Frequent shock loads
• Aging and obsolete equipment for which replacement parts are no longer readily available

The cost of a gearbox failure in a paper mill can range from tens of thousands of dollars to over a million dollars a day. Savvy mill operators know this and rely on scheduled maintenance and scheduled gearbox rebuilds to prevent failures. We know this too and have spent more than 30 years keeping their gearboxes running.

Founded in 1988, AGW began stocking and servicing Beloit differential gearboxes, PIV’s and transfer cases for line-shaft paper machines across the country. Today, we repair and rebuild any and all brands of process-critical gearboxes including pulpers, paper machines, vacuum pumps and other gearboxes used in the paper-making process.

In addition to gearbox repair, we manufacture custom gearing for replacement, even obsolete parts, and provide world-class field machining and other field services. Whether it is a washer drum journal, a dryer section bore or a critical gearbox that needs to be rebuilt in place, our Field Machining and Services division can help.
