Bearings

Amarillo Gear is an industry leader with L10a bearing life exceeding 100,000 hours on all bearings. Input and intermediate bearings provide double the service life specified in AG MA and CTI standards, resulting in lower maintenance costs. The fan shaft bearings are designed to carry all loads imposed by the fan while maintaining this outstanding bearing life. Only trusted name brand bearings such as Timken and SKF are installed in Amarillo fan drives.
 

Quiet Operation

Quiet operation of the Amarillo Fan Drives is achieved through careful design and controlled manufacturing methods of components.
 

Shaft Seals

Both the input and output shaft openings have 2 spring-loaded, single-lip seals to keep outside contamination from entering the gearbox.
 

Lubrication

Oversized slinger on the input shaft provides excellent lubrication in either direction or at half speed operation.
 

Low Speed Operation

For operation when motor speeds are less than 450 rpm, single reduction fan drives require Amarillo Gear's exclusive KLow Speed" option, and double reduction fan drives require a mechanical oil pump for proper lubrication. The addition of these options allow operation with no minimum input speed restrictions.
