Throughout the world, regardless of the unique weather conditions or crop yields, the use of reliable and durable components is a key factor in ensuring proper maintenance and timely harvesting of agricultural machinery.

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

Agricultural machinery bearings must be able to operate in extremely challenging conditions, adapting to environments ranging from dry and abrasive to humid, corrosive, and highly polluted. They must meet the requirements of long lifespan and durability under heavy load conditions, in order to solve the severe challenges of reducing downtime and maintenance costs for farmers, and maximizing output.

Characteristics of agricultural machinery bearings

1. Capable of withstanding sustained vibrations and high impact loads;

2. Thorough and high-precision sealing design ensures reliable operation under various weather conditions;

3. Low maintenance or maintenance free design;

4. Easy to install, can provide a complete unit;

5. The structural design is very simple;

6. Ensure efficient utilization of the machine;

There are also many types of equipment in agricultural machinery, with different usage scenarios and purposes, so the bearings used will also be different. The commonly used bearings in agricultural machinery include: agricultural machinery ball bearings (round hole, square hole or hexagonal hole, locking ring, relubricating oil hole or nozzle), angular contact ball bearings, outer spherical bearings, needle roller bearings, tapered roller bearings, etc.

Farming and sowing machinery

The high humidity in spring and autumn is the true test of agricultural cultivation. The hard soil tests the ultimate strength of all mechanical parts, which requires stronger bearing capacity of the bearings of the cultivation machinery.

Farming machinery bearings are usually integrated with bearing seats with flanges to simplify assembly. If the plow disc is connected to the bearing and installed on the plow surface with a certain inclination angle, the bearing needs to withstand lateral loads, overturning moments, and radial loads.

The bearing unit includes

Double row angular contact ball bearings, derived from the wheel hub bearing series of automobiles - high load-bearing capacity, high lateral stiffness, double-sided sealing;

Corrosion resistant protection machining bearing seat;

Threaded pin with positioning surface;

Anti loosening gasket.

The products applied to 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 inner hole bearings, as well as idler gear units and chain drive idler gear tooth units.

Tractor

Transmission bearings and components

Large radial and axial loads make cylindrical roller bearings without outer rings particularly suitable for planetary gearboxes.

Conical roller bearings are suitable for hydraulic motors, hydraulic pumps, small bevel gear shaft supports, and rear axle drives integrated with gearboxes.

Application in chassis

The outer ring belt applied at the hinge point of the front axle spring end of the chassis can only lubricate the joint bearings of the system;

Applied to the maintenance free rod end key bearings of the front axle steering system with independent suspension.

Engine components and systems

In tractor engine applications, there are components such as belt drive parts, tensioning wheels, and generator overrunning pulleys, water pump and fan bearings, as well as needle roller cage components for linkage mechanisms.

Harvesting Machinery

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

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