This guide to Fairfield Torque-Hub® drive ratings and technical issues has been created to help you in selecting the proper Fairfield product for your application, as well as address the frequent questions that arise pertaining to available product options, features, and service issues. Our standard
Torque-Hub® drives are available with maximum output torque ratings from 12,000 in-lbs up to 4,000,000 in-lbs, with ratios from 3:1 to more than 1,100:1.
The Fairfield approach to drive system applications centers around the belief that thorough"front-end"application engineering practices, field testing and in-depth communication with our customers and their designers, we'll provide you with the best drive system. We pay particular attention to gear
and bearing life, and feel that it is extremely important that our customers know how we obtain our product ratings.
General Properties
The lubricant used in all Torque-Hub® drives should be a petroleum based, non-detergent gear fluid containing antioxidation, antifoaming and
extreme pressure additives. The lubricant should have a minimum viscosity index of 95 cst and maintain a minimum viscosity of 40 cst under
normal operating temperature conditions.
The following table lists the recommended viscosities for various ambient operating temperatures.
These recommendations are based on a temperature rise of 50º to 100º F at normal operating conditions.
Maintenance
Oil amounts for each series of Torque-Hub® drives are indicated in the appropriate series literature.
An initial oil change should be made after the first 50 hours of operation. Subsequent oil changes should be made at 1000 hour intervals or annually, whichever comes first. Oil temperature should be no higher than 160º to
180º for continuous operation, and no higher than 200º F for intermittent operation. For special applications, high horsepower, high speeds or wide temperature changes, please consult Fairfield Manufacturing.
Oil Fill Level
When the Torque-Hub® unit is mounted horizontally, the gearbox should be filled half-full of oil. Consult the appropriate series literature for
approximate fill volumes. Vertically mounted Torque-Hub® units may require special lubrication procedures. Please contact Fairfield Manufacturing
for vertically mounted applications.
