About the Lufkin N1800C
Lufkin gear drives are the standard for oil & gas and heavy industrial applications. N-series and S-series parallel shaft units handle the high-torque, high-reliability demands of pump jacks, compressors, and mill drives. Now part of GE Oil & Gas (Baker Hughes), Lufkin units are built to API standards and are highly rebuildable.
The N1800C is a parallel shaft, double reduction unit with a rated capacity of 150–450 HP and output torque of 46,000–184,000 ft-lb. Typical operating weight is 2,100–3,855 lbs. Mounting configurations include Foot.
Lufkin units most commonly fail from gear tooth pitting in high-load oilfield applications, bearing fatigue in continuous-duty operations, and seal failure in outdoor oilfield environments.
When your Lufkin N1800C 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.
