Agricultural equipment requires bearings that can withstand a variety of difficult conditions. This includes exposure to dirt, mud, extreme temperatures, and chemical contaminants.
This is why agricultural bearings are often designed with proper sealing and low maintenance requirements. These features make them an excellent choice for a wide range of equipment.
Rolling element bearings carry loads by placing rolling elements (usually balls or rollers) between two concentric, grooved rings called races. Their relative motion allows the rolling elements to roll with very little rolling resistance and without sliding friction.
As a result, rolling element bearings require very little maintenance to maintain their performance throughout their life. These bearings can also operate at higher speeds than plain bearings.
But, just like any other mechanical part, rolling element bearings can wear out and fail. Several factors, including improper installation, lack of lubrication and alignment with other components, can lead to premature bearing failure.
Agricultural machinery requires bearings that are reliable and durable in extremely harsh conditions. This means they must withstand shock loads, dust and dirt, as well as high pressure washing.
Moreover, they must be corrosion-proof and maintain grease in the interior so that it remains protected from contamination when crops like hay or straw are being gathered. In addition, the shaft and housing mountings must be cost-effective.
Plain bearings spread cyclical load over a larger surface, reducing contact stresses and the risk of fatigue damage. They also distribute lubrication over the full surface of the raceway and minimize the churning caused by rolling elements.
Fortunately, there are many health monitoring techniques available for rolling element bearings, some of which can be used to detect early signs of a fault or defect before it becomes severe. Among the techniques, vibration-based health monitoring is most commonly utilized, as it provides information on the condition of the bearing without interrupting the operating cycle. Agricultural machinery uses rolling-element bearings in a variety of applications, including pumps, steering systems, air-conditioning compressors, engine rocker arms, throttle butterfly valves, gearboxes, and transmissions. These components can be converted to plain bearings at a relatively low cost.
Agricultural machinery often operates in harsh environments, and it is critical to maintain reliable operations. These machines require a tough, durable bearing that can withstand repeated impacts of stones and other shock loads. Spherical Roller Bearings are the best option for a variety of applications. They can handle heavy radial load and angular misalignment.
They also have a lower bearing diameter than other types of ball bearings, which allows for a smaller overall size. This means that less space is required for the housing and shaft.
Agricultural bearings are used in a variety of equipment, including tractors, diesel engines, electric motors, rakes, balers, harvesters, and threshers. These machines need to be able to withstand rough operating conditions.
Single-row cylindrical roller bearings feature a separable inner and outer ring, and can support heavy radial forces. They also withstand impact loads.
They are typically used in gearboxes, pumps, compressors and electric motors. They can also be used in hydraulic and pneumatic systems.
The ribs on the inner and outer rings of the bearings help to guide the rolling elements. The ribs can be either integral or double, depending on the type of bearing.
Cages are often made from pressed steel or machined brass, but polyamide resin cages can be used in certain models. NTN has developed a technology that allows cylindrical roller bearings to have the same load capacity as full complement bearings, but with the high rotational speed capabilities of a caged design. They also offer a self-aligning feature that increases performance and reduces installation requirements. They are primarily used in harvesting machinery, where they are easy to install and can compensate shaft misalignment within a certain range.
