In light of growing food insecurity in some parts of the world, agricultural machinery can play an important role in helping to efficiently achieve stable yields from crop production. Various types of agricultural implements are used depending on environmental conditions and manner of specific crop production in a given country or region.

Tractors are the primary machines used in crop production and handling work. By mounting implements to a tractor's drawbar or power take-off (PTO), fields can be cultivated, seeds can be planted, fertilizers and be spread, and agricultural chemicals can be applied.

Bearings are used throughout various components of the tractor such as the engine, transmission, wheel hubs, etc. under muddy working conditions and heavy load conditions.

Moreover, tractors and implements that are used in the vast fields of some farms in Europe and North America are huge, which place severe demands on the bearing. It is under such harsh working conditions that customers expect bearings to be highly reliable while offering superior cost performance. 

NSK applies various technologies to the manufacture of bearings to meet customer needs, including heat-treatment technology for higher reliability under muddy working conditions, material technology for greater endurance under heavy-load conditions, and optimum design technology for longer service life. In constantly striving to enhance various technologies, NSK is a significant force that supports agricultural worldwide.

NSK Bearings for Tractors

Tractors are the most common and significant investment for farmers. Whatever the task, they are primarily units for hauling or powering machinery such as seed drills and reapers, round balers, ploughs, harrows and manure spreaders. Because of this tractors have to work very precisely and efficiently and must be capable of withstanding the great demands placed on them during operation, where different application and climate parameters can lead to corrosion, vibration and dirt.

Performance, efficiency and reliability are the key considerations when choosing a tractor, and high-performance bearings play a major role in th equipment. NSK cultivates long-standing partnerships with leading tractor manufacturers around the world using our expertise and experience, we  help engineers to find the ideal solutions.


Double-row tapered roller bearings for tractor transmissions

Double row tapered roller bearing was specifically designed for tractor gearboxes. One row is manufactureres with long rollers, to accept high loads; while the other row is equipped with small tapered rollers. This combination minimizes the energy loss due to friction. The double-row was was also designed to make handling and fitting into the housing easier, saving time and money.

NSK Flanged Bearing for Agriculture

Land quality is critical to a farmer's success. Good soil ensures that crops have optimal growth and contain the best nutrients vital for dietary needs.

To safeguard this need for quality, farmers rely on high-grade machinery. This is the only way for their soil to be cultivated so that it delivers the very best harvests long term.

Circular spike harrows provide the ideal preparation for plant growth and high-yield crops. Disc harrows create the perfect mixture of straw and soil which stimulating decomposition and enhancing the soil’s natural nutrients.
Machinery must be reliable – even in difficult conditions withstanding the strain placed on it every day.

Sowing is crucial for plant growth. Timing and weather are very important but the use of seed drills ensures that the farmer will be able to reap a rich harvest. Modern seed drills measure out the quantity of seeds, ensuring that they are distributed evenly reducing waste and assuring proper spacing for optimal plant growth.

Seed-spacing drills do face particular challenges. In addition to having to adjust to a wide range of soils and cultivation methods, they have to be robust and reliable and able to sow all types of seed precisely.

Before and after sowing, the soil is fertilized to boost the plants nutrients. This typically enables farmers to generate higher yields and faster growth. With flexible agricultural machinery farmers can ensure that the fertilizing process is effective, economical and ecological.

Double-row angular-contact ball bearing (DRACBB)

NSK double-row angular-contact ball bearings offer exceptional protection against contamination, while reducing wear on the ball and raceway surface. Double -row also limits noise and vibrations, and minimizes the risk of lubricant failure. DCACBB can absorb radial and axial forces in both directions helping farmers achieve optimum results.

NSK Bearings for Combine Harvesters

The harvest what ultimately counts and where hard work over the previous months pays off.
However, farmers can also optimize their results by boosting the effectiveness and economic efficiency of their harvesting which calls for agricultural machinery of the highest standard.

The combine harvester is an important machine for harvesting grain, rape, maize and other agricultural crops and is capable of completing several tasks. Combine harvesters are exposed to extreme loads during harvesting and its imperative that they do not fail.

Flanged bearing unit

NSK’s newly developed flanged bearing units have a special seal with an outer facing flinger makes them ideal for use in dusty conditions and to harvest a range of crops.

Field choppers

Field choppers have proven to be particularly valuable for harvesting renewable plants, primarily grass, alfalfa, maize and whole-crop silage. The harvested crops are fed to the chopping unit, where a fast-rotating chopping drum shreds the material. During the harvest choppers have to be reliable –in all terrain and any raw material.

Total Quality Solution:
Pulley Bearings

NSK’s innovative pulleys help to ensure that machinery operates reliably. The seal on the angular contact ball bearings prevents contaminants from entering the components and guarantees usability. The bearings are designed and work like a pair of single-row angular-contact ball bearings with a reinforced outer ring in an O-shape. However, they offer more reliable performance.

NSK bearings for haymaking machines

Self-propelled large-scale reapers are the most commonly used in haymaking machines ensuring that the grass is cut and can be used as animal fodder over winter.
Cuts are left out in the fields for several days before they are brought in to dry. To ensure they dry quickly they are repeatedly turned by tedders and formed into windrows by rotary swathers. It is important that the machines adjust optimally to the terrain. In conjunction with the machine suspension, this ensures that the hay is not damaged and the fodder remains uncontaminated.

Once dry, balers are normally used to form the hay into round or square bales that can weigh up to several hundred pounds and can last over a year in storage.


Inserts with a triple-lip seal

NSK’s innovative triple-lip seal bearings are ideal for combine harvesters and rotary swathers. They protect the bearings from dust, dirt, water and other contaminants, thereby ensuring a longer service life. Longer life means less replacement and reduced cost.
