Agricultural Bearings

Agricultural Bearings

The use of reliable and durable bearings is critical to adequately maintaining agricultural machinery and harvesting crops in a timely manner. Agricultural engineering involves a wide range of machinery, equipment and tools, most of which are specially designed and manufactured according to the characteristics of agriculture and the special requirements of various agricultural operations, such as agricultural vehicles, tractors, diesel engines, rakes, balers, Harvesters, threshers and other agricultural machinery, etc.

All kinds of mechanical equipment need to face the harsh working environment. The dust in summer has very high requirements on bearing sealing, and the high humidity in spring and autumn is a great test for farming. The hard soil tests the ultimate strength of all mechanical parts; vibration and high-intensity impact also determine that agricultural machinery bearings have a stronger load-bearing capacity. The precision, performance, life and reliability of agricultural machinery bearings play an important role in the continuous operation of machinery, and they also need to meet the requirements of long life and durability under heavy load conditions to help farmers reduce downtime and maintenance costs and increase production

Agricultural Machinery Bearings

Features of agricultural machinery bearings:

  • Can withstand continuous vibration and high shock load

  • High-precision sealing design to meet reliable operation under various climatic conditions;

  • Low maintenance or maintenance-free design

  • Easy to install, can provide all-in-one machine

  • Simple structural design

  • Ensure the long-term stable operation of the machine

There are also many types of equipment in agricultural machinery, which are used for different occasions and purposes, so the bearings are also different. The following are the types of bearings commonly used in agricultural machinery:

  • Angular contact ball bearings

  • Pillow block bearings

  • Needle roller bearings

  • Tapered roller bearings

The peak agricultural seasons in spring and autumn are the real test of agricultural cultivation. The hard soil challenges the strength of all mechanical parts, which requires agricultural machinery bearings to have stronger load carrying capacity. Tillage machinery bearings are often integrated with flanged bearings to simplify assembly. For example, the coulter disc connection bearings are installed at a certain inclination on the plow surface. Bearings are required to withstand lateral loads, overturning moments and radial loads.

Typical applications of agricultural bearings

Products for agricultural machinery include housed and housing units, sealed deep groove and angular contact ball bearings, tapered roller bearings, hexagonal and square bore bearings, idler units and chain drive idler gear units.


  • Gearbox bearings and components.

  • Large radial load and axial load, cylindrical roller bearings without outer ring are especially suitable for planetary gearboxes.

  • Tapered roller bearings are suitable for hydraulic motors, hydraulic pumps, gearbox pinion shaft supports, and rear axle drives integrated with gearboxes.

  • Application in the chassis

  • The outer ring used in the hinge point of the spring end of the front axle of the chassis has a joint bearing that can only lubricate the system;

  • Independent suspension front axle steering system key maintenance-free rod end bearing;

  • Engine components and systems

  • In tractor engine applications, belt drive components, tensioner and generator overrunning pulleys, water pump and fan bearings, and needle roller and cage assemblies for linkages.

Harvesting Machinery

In agricultural engineering applications, wherever there are rolling bearings, there are seals. A good seal serves two important functions: keeping high-quality grease inside the bearing and keeping contaminants and moisture out. Effective sealing increases the service life of bearings and also extends the working life of agricultural machinery. Bearing units are mainly used in harvesting machinery in the field of agricultural machinery. Mounted bearings and housings are easy to install and can compensate for shaft misalignment within a certain range.
