Bearings & Components for Harvesting Machinery

Harvest is one of the busiest periods in the agricultural calendar, making reliable machinery essential when crops are ready to be collected. Combine harvesters, balers and other harvesting equipment rely on bearings, belts, chains, sprockets and other moving components to keep drive systems and rotating assemblies operating efficiently.

Dust, crop debris, heavy loads and prolonged operation can place considerable demands on these components. Regular inspection and maintenance of harvesting machinery can help identify wear before it leads to unexpected breakdowns and costly downtime during the harvest season.

Discover how Simply Bearings supports the agriculture industry with bearings, seals, power transmission and engineering components for a wide range of farm machinery applications.

Components Used in Combines, Balers & Harvesters

Agricultural Bearings

Bearings are used throughout combine harvesters, balers and other harvesting machinery, supporting shafts, rollers, pulleys, wheels and numerous rotating assemblies.

Depending on the application, agricultural bearings, deep groove ball bearings, insert bearings and housed bearing units may be required. Components operating in dusty environments can also benefit from appropriate sealing arrangements to help protect against contamination.

Agricultural Belts

Belts are an important part of many harvesting machines, transferring power between shafts, pulleys and driven assemblies.

Agricultural belts and V-belts can be exposed to heat, dust, heavy loads and prolonged operation during harvesting. Regular checks for cracking, glazing, fraying, stretching and incorrect tension can help identify belts that may require replacement before failure occurs.

Correct belt selection and tension are also important for reliable power transmission and service life.

Chains & Sprockets

Roller chains and sprockets are widely used throughout agricultural machinery to transfer power and synchronise moving assemblies.

During harvesting, chains can experience sustained loads and contamination from dust and crop debris. Checking chain tension, lubrication, wear, and sprocket teeth condition can help maintain reliable drive performance.

Replacing excessively worn chains and sprockets before failure can help reduce the risk of unexpected downtime during critical harvesting periods.

Bearing Housings

Bearing housings and mounted bearing units provide secure support for rotating shafts across many types of harvesting machinery.

Correctly selected bearing and housing combinations help maintain shaft alignment while providing a practical solution for replacing worn bearing units.

Regular inspection for excessive movement, contamination and lubrication condition can help identify developing problems before they affect other components.

Maintaining Harvesting Machinery

Before harvest begins, inspect bearings, belts, chains, sprockets, housings and other moving components for signs of excessive wear or damage.

Bearings should rotate smoothly without unusual noise, vibration or excessive play. Check belts for wear and correct tension, and inspect chains and sprockets for stretching, damaged teeth and adequate lubrication.

Dust and crop debris can accumulate around moving components, so regular cleaning and inspection throughout the harvest period can also help identify potential problems.

When replacing a bearing, belt or other engineering component, use the existing part number and accurate dimensions wherever possible to help identify the correct replacement.
