About the Boston Gear 715
Boston Gear's 700 and 900 series worm reducers are among the most widely used gear drives in light-to-medium industrial applications. Their simple worm gear design is highly rebuildable, and Altra Industrial Motion maintains good parts availability. The F-series parallel shaft units handle heavier applications.
The 715 is a worm gear unit with a rated capacity of 0.33–1 HP and output torque of 160–640 ft-lb. Typical operating weight is 9–17 lbs. Mounting configurations include Foot, flange.
Boston Gear worm units most commonly fail from worm gear wear (bronze worm wheel against steel worm), seal failure causing oil loss, and bearing fatigue in high-cycle applications.
When your Boston Gear 715 fails, downtime costs mount fast. Our standard rebuild turnaround is 8–14 business days with free freight both directions. Emergency 24–72 hour service is available. We publish pricing before teardown — no surprises.
