# Bearings for Combine Harvesters

## Combine Harvesters: The Most Complex Agricultural Machinery

Grain combine harvesters contain over 200 bearings of various types. They operate under conditions of high loads, vibrations, dust, and temperature fluctuations. Failure of even one bearing can lead to the entire combine stopping during the peak harvest season.

## Main Combine Components

- **Cutting Table:** cutting mechanism, reel, auger, conveyor
- **Threshing Unit:** drum, straw walker, straw discharge
- **Grain Cleaning System:** fan, sieves, elevator
- **Engine:** attachments, drives
- **Running Gear:** wheels, hydraulic motors
