Whether it’s traversing rough terrain or navigating through fields, bearings ensure the mobility and manoeuvrability of agricultural equipment, enhancing overall productivity.

Steering Mechanisms

Bearings are employed in tractors at specific points such as steering columns, linkages, and joints, facilitating smooth movement and precise control of the steering system. This enables farmers to manoeuvre their equipment with ease, whether it’s turning corners in the field or navigating narrow pathways. By providing reliable steering control, bearings enhance the safety and efficiency of agricultural operations, allowing farmers to optimise their fieldwork practices.

Low Friction Performance

Bearings in agricultural machinery are designed to minimise friction and wear, ensuring smooth operation and prolonged lifespan of the equipment. Low friction bearings like Ceramic bearings reduce energy consumption and enhance fuel efficiency, making them ideal for agricultural applications where maximising productivity while minimising operating costs is paramount. Additionally, low friction bearings contribute to reduced maintenance requirements, as they experience less wear and tear over time, resulting in decreased downtime and higher uptime for agricultural machinery.

Bearings used in agricultural machinery are engineered to withstand the demanding conditions encountered in field operations. They are designed to endure heavy loads, shocks, and vibrations associated with traversing uneven terrain and performing various tasks in the field. By providing reliable performance under harsh environmental conditions, bearings ensure the durability and longevity of agricultural equipment, allowing farmers to rely on their machinery for uninterrupted operation throughout the farming season.

Powering Harvesting and Processing Equipment

In the agricultural sector, bearings are essential for powering a wide range of harvesting and processing equipment. They facilitate smooth rotation and movement, enabling efficient harvesting and processing of crops with minimal downtime. Additionally, bearings withstand heavy loads and dynamic forces encountered during operation, ensuring reliable performance even in demanding conditions.

Some of the main applications in agriculture include combine harvesters, threshers, and milling machines. Bearings are utilised in various components of these machines, such as the rotor assemblies, augers, and conveyor systems.

Powering Harvesting and Processing Equipment

Combine Harvesters

Bearings are integral components of combine harvesters, which are used for harvesting a variety of crops such as wheat, rice, and corn. Within the rotor assemblies of combine harvesters, bearings support the rotating shafts and mechanisms responsible for cutting, threshing, and separating the harvested crop from the stalks. Bearings enable smooth rotation of the rotor assemblies, allowing for efficient crop harvesting and separation processes.


Threshers are agricultural machines designed to separate grains from harvested crop stalks. Bearings are utilized in the moving parts of threshers, including the drum assemblies and rotating blades. These bearings facilitate the smooth rotation of the threshing components, enabling effective separation of grains from the crop stalks. By withstanding the heavy loads and dynamic forces encountered during threshing operations, bearings ensure reliable performance and minimize downtime.

Milling Machines

Milling machines are used in the agricultural sector for processing harvested grains into various products such as flour, feed, and cereals. Angular contact ball bearings play a crucial role in the conveyor systems and milling mechanisms of these machines. They support the rotating shafts and rollers responsible for grinding and milling grains, facilitating the smooth movement of the milling components. Bearings withstand the high loads and rotational speeds associated with milling operations, ensuring consistent and efficient processing of harvested crops.

In addition to facilitating smooth rotation and movement, bearings in agricultural equipment must withstand heavy loads, shocks, and vibrations encountered during operation. Their ability to withstand these dynamic forces ensures reliable performance and minimizes the risk of equipment failure or downtime, thereby enhancing overall productivity in agricultural operations. By enabling efficient harvesting and processing of crops with minimal downtime, bearings contribute to the optimization of agricultural processes and the maximization of crop yields.

Water Management Systems

Water management is critical in agriculture, and bearings play a crucial role in powering essential components of irrigation and water management systems. Bearings are utilized in pumps, valves, and rotating irrigation equipment, enabling efficient water distribution and management across agricultural fields.

Water Management Systems


Whether it’s submersible pumps deployed for drawing water from wells or centrifugal pumps utilised for surface water irrigation, bearings facilitate the rotational movement of pump shafts and impellers. By reducing friction and enabling smooth rotation, bearings ensure the efficient transfer of mechanical energy from the motor to the pump, thereby facilitating the lifting and transportation of water to agricultural fields.


Within irrigation systems, valves control the flow of water, directing it to specific areas of the field as per the requirements of different crops and soil conditions. Bearings are integral components of valve assemblies, supporting the moving parts such as stems, discs, and gates. These bearings enable the smooth operation of valves, allowing precise regulation of water flow rates and pressures. By ensuring reliable valve performance, bearings contribute to the accurate and efficient distribution of water, optimising irrigation practices and maximising water utilisation.

Rotating Irrigation Equipment

In modern irrigation techniques such as centre pivot and linear move systems, rotating equipment plays a crucial role in uniformly distributing water across large agricultural areas. Bearings are essential components of rotating irrigation equipment, including pivot points, towers, and wheel assemblies. These bearings enable smooth rotation and movement of the irrigation equipment, ensuring even coverage of water over the entire field. By maintaining consistent rotational motion without frictional resistance, bearings contribute to efficient water distribution, enhancing crop irrigation practices and promoting optimal crop growth.

Therefore, whether it’s pumping water from wells or distributing irrigation water through sprinkler systems, bearings ensure smooth operation and reliability, contributing to effective water conservation and crop irrigation practices.

Poultry Farming Operations

In poultry farming operations, bearings are utilised in various equipment essential for feed processing, mixing, and manure handling. Bearings are integral components of feed processing equipment, such as hammer mills and pellet mills, facilitating the grinding and pelleting of feed ingredients.

Additionally, bearings support the rotating shafts of feed mixers, ensuring thorough blending of feed components for optimal nutrition. Furthermore, bearings are employed in manure spreaders, facilitating the efficient distribution of organic fertilisers across agricultural fields.

Post-Harvest Handling and Storage

Post Harvest Handling and Storage

After harvesting, efficient post-harvest handling and storage are essential for preserving the quality and value of agricultural produce. Bearings play a vital role in conveyor systems, elevators, and handling equipment used in post-harvest operations. Bearings enable smooth movement and transport of harvested crops along conveyor belts and elevators, facilitating sorting, grading, and packaging processes. Bearings also support the moving parts of handling equipment, such as bucket elevators and grain augers, ensuring reliable performance during grain storage and transportation. Here’s a look at how each component of the handling and storage machines benefit from bearings.
