Things You Should Know about Agricultural Machinery Bearings

Significance

Agricultural machinery bearing is an important basic component of agricultural machine, which is widely used in agricultural machines such as agricultural vehicles, tractors, diesel engines, electric motors, rakes, baler, harvester, and thresher. Its quality plays a decisive role in the accuracy, performance, service life and reliability of the machine itself. Agricultural machinery bearings must be able to endure extremely demanding conditions such as dry or wet environment and corrosive and highly polluted surroundings. They need to have long service life and be durable under heavy load conditions, so as to reduce downtime and maintenance costs, and maximize output.

 

 

Characteristics

1. Sustainable to continuous vibration and heavy load;

 

2. Tight and high-precision seal design; operational under various weather conditions;

 

3. Low-maintenance or maintenance-free design;

 

4. Easy to install;

 

5. Simple structural design;

 

6. High efficiency;

 

Types

There are many types of agricultural machine, which can be used in different occasions. The commonly used bearings in agricultural machinery are: agricultural machinery ball bearings (round hole, square hole or hexagonal hole, lock ring, relubrication) Oil hole or nozzle), angular contact ball bearing, spherical bearing, needle roller bearing, tapered roller bearing, etc.

 

 

The Importance of Sealing

In agricultural engineering applications, where there are rolling bearings, there are sealing. A good seal has two important functions: maintaining high-quality lubricant inside the bearing and preventing contaminants and moisture from entering the bearing. Good sealing increases the service life of bearings, and also extends the working life of agricultural machinery.

 

 

How to Judge the Quality of Bearing

Hold the inner ring, and then rotate the outer ring to see whether it rotates smoothly and quickly.

 

Bearings of resin seal and metal seal cannot rotate quickly because butter is sealed in the middle of the bearing. If it can rotate quickly, it  means there is no butter in the middle of bearing and that bearing needs to be replaced.

 

Check whether the inner ring can be shook out of the outer ring.

 

Bearing installation

Garbage and dust should be cleaned, and bearing should be cleaned carefully with cleaning oil before installing. During installation, especially when inserting the bearing into the shaft, you should slowly push the bearing into the shaft using a hydraulic press. Apply high-viscosity oil to the inner and outer diameter of the bearing before pressing.

 

 

Therefore, before starting tractors or thrashers, we should do a thorough examination first. Although bearings are durable, we should also check it once in a while. Besides, the tractor chassis is easy to break. So when driving, you must pay attention to tractor chassis fatigue, never overwork your tractor. But if your original one is already broken and beyond reparation, there are a lot tractor trailer chassis for sale. Remember to be careful when choosing tractor chassis types, tractor chassis material and tractor chassis number.
