About the Philadelphia Gear 900C
Philadelphia Gear drives — now part of Timken Power Transmission — are found in power plants, steel mills, and heavy industrial applications across the US. The 100C series and Paramax units handle the highest-torque applications in the industry. Built to demanding power generation standards, these units are highly rebuildable.
The 900C is a parallel shaft helical unit with a rated capacity of 300–1,000 HP and output torque of 107,000–428,000 ft-lb. Typical operating weight is 7,400–13,590 lbs. Mounting configurations include Foot, flange.
Philadelphia Gear units most commonly fail from gear tooth pitting in high-load power generation applications, bearing fatigue in continuous-duty operations, and coupling wear.
When your Philadelphia Gear 900C 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.
