A-Series Drives

The “A” Series right angle gearboxes from Amarillo Gear are designed as direct replacements for the Marley ® line of gear reducers.

Since the critical mounting dimensions are identical to the Marley ® gear reducers, the Amarillo “A” Series will make gearbox replacement easy. This includes gear case mounting holes, horizontal alignment with motor shaft, and overall output shaft height. Ratios are within ±2% of the Marley ® gear reducers.

Drive Shafts

Amarillo Gear designs and manufactures the industry’s most reliable composite drive shafts for wet cooling. The Amarillo Composite Drive Shaft is the perfect complement to the Amarillo Right Angle Gear Drive. Each drive shaft connects the electric motor to the gearbox input shaft, thereby transmitting torque to rotate the cooling tower fan.

Amarillo Gear drive shafts are custom manufactured and engineered for specific applications to achieve optimum performance. The Amarillo Composite Drive Shaft will accommodate spans ranging from 2 feet in small HVAC towers, to over 20 feet in large field erected towers.
