Around the world, regardless of the weather or crop yield, the use of reliable and durable parts is a key factor in the proper maintenance of agricultural machinery and timely harvest of crops.

Agricultural machinery bearings are important basic parts of agricultural machinery equipment. They are widely used in agricultural vehicles, tractors, diesel engines, electric motors, mowers, balers, harvesters, threshers and other agricultural machinery. Their accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the main machine.

Agricultural machinery bearings must be able to operate under extremely challenging conditions, adapt to environments from dry and abrasive to wet, corrosive and highly polluted environments, and meet the requirements of long life and durability under heavy load conditions, so as to solve the harsh challenges of farmers to reduce downtime and maintenance costs and maximize output.

Characteristics of agricultural machinery bearings :

1. Able to withstand continuous vibration and high impact loads;

2. Careful and high-precision sealing design to ensure reliable operation under various weather conditions; 3. Low-maintenance or maintenance-free design;

4. Easy to install, can provide integral units;

5. Very simple structural design;

6. Ensure efficient utilization of the machine;

There are also many types of equipment in agricultural machinery, and the occasions and uses are different, so the bearings used will also be different.

Commonly used bearings in agricultural machinery are: agricultural machinery ball bearings (round holes, square holes or hexagonal holes, lock rings, relubricating oil holes or oil nozzles), angular contact ball bearings, pillow block bearings, needle bearings, tapered roller bearings, etc.

Tillage and sowing machinery

The high humidity in spring and autumn is a real test for agricultural farming. The hard soil tests the ultimate strength of all mechanical parts, which requires a stronger bearing capacity for the bearings of the tillage machinery. Tillage machinery bearings are usually integrated with bearing seats with flanges to simplify assembly. For example, the plow disc connection bearing is installed at a certain inclination angle to the plow surface, and the bearing needs to bear lateral loads, overturning moments and radial loads. Bearing units include Double-row angular contact ball bearings, derived from the automotive wheel hub bearing series - high load capacity, high roll stiffness, double-sided seals; Corrosion-resistant machined bearing seats; Threaded pins with locating surfaces; Anti-loosening washers. Products used in tillage machinery include outer spherical ball bearings and bearing seat units, sealed deep groove ball bearings and angular contact ball bearings, tapered roller bearings, hexagonal and square bore bearings, as well as idler units and chain drive idler gear units. Tractors Gearbox bearings and components Larger radial loads and axial loads, cylindrical roller bearings without outer rings are particularly 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. Applications in chassis Applied in the outer ring of the hinge point at the end of the spring of the front axle of the chassis with only lubricated joint bearings of the system; Applied in the maintenance-free rod end key bearings of the steering system of the front axle with independent suspension. Engine components and systems Belt drive components, tensioners and generator overrunning pulleys in tractor engine applications, water pump and fan bearings, and needle cage components of connecting rod mechanisms.

Harvesting machinery

In agricultural engineering applications, seals are found wherever there are rolling bearings. Good sealing has two important functions: maintaining high-quality grease inside the bearing and preventing contaminants and moisture from entering the bearing. Efficient sealing increases the service life of the bearing and also extends the working life of agricultural machinery.

External spherical ball bearings are mainly used in harvesting machinery in the field of agricultural machinery. External spherical ball bearings and bearing seat units are easy to install and can compensate for shaft misalignment within a certain range.
