A roller drive planetary gearbox is a type of gearbox that uses a planetary gear set to transfer torque and power from the input shaft to the output shaft. It is designed to handle high torque and radial loads and is suitable for a wide range of applications. The gearbox consists of a sun gear, planet gears, and a ring gear. The planet gears rotate around the sun gear, which is fixed in the center, and mesh with the ring gear to transfer power to the output shaft. The compact design of the gearbox makes it ideal for applications where space is limited.
We offer a range of roller drive planetary gearboxes that are similar to the Fairfield CR31A2 model. Our gearboxes are available in various sizes and can be customized to meet your specific requirements. We can match Fairfield's gearbox dimensions, installation methods, and technical parameters to ensure a seamless replacement. Our standard torque hub drives can provide maximum output torque ratings from 12,000 in-lbs to 4,000,000 in-lbs, with gear ratios ranging from 3:1 to 1100:1 or more. It is important to note that we do not sell Fairfield branded products. We only mention the brand for customers' convenience when selecting a replacement gearbox.

Our roller drive planetary gearbox offers several advantages over other types of gearboxes. Some of the key features include:

Our roller drive planetary gearbox is suitable for a variety of applications, including:
When selecting a roller drive planetary gearbox, it is important to consider the following parameters:
| Parameter | Description |
|---|---|
| Maximum output torque | The maximum amount of torque that the gearbox can transfer to the output shaft. |
| Gear ratio | The ratio of the rotational speeds of the sun gear and the ring gear. |
| Input speed | The maximum rotational speed of the input shaft. |
| Output speed | The maximum rotational speed of the output shaft. |
| Operating temperature range | The range of temperatures within which the gearbox can operate safely and reliably. |
Proper lubrication and maintenance are essential for the long-term performance and reliability of our roller drive planetary gearbox. We recommend using high-quality lubricants and following the manufacturer's recommended maintenance schedule. Regular inspections and maintenance can help to prevent issues and extend the life of the gearbox.
