During the agricultural season, every minute of downtime means serious costs. An incorrect disc harrow bearing can easily cause vibration, premature wear, or even unexpected machine failure.
For independent disc harrows, checking AGRIHUB compatibility before replacement is especially important.
But how can you quickly identify the right AGRIHUB bearing?
Based on NTN-SNR’s professional recommendations, here are 3 simple methods to help you choose the correct disc harrow bearing faster and more safely.
What is AGRIHUB and why is it important?
AGRIHUB is a complete disc harrow bearing unit specifically designed for independent disc harrows.
The unit includes:
- bearings,
- seals,
- protective components,
- and a robust steel housing.
Its purpose is to ensure:
- smooth disc rotation,
- proper handling of radial and axial loads,
- and protection against dust, mud, and moisture.
Modern agricultural machinery operates under increasingly demanding conditions. High-speed soil cultivation, wet environments, and constant vibration make reliable sealing and durable bearing performance more important than ever.
How to choose the correct AGRIHUB unit?
Several technical factors must be considered when checking compatibility:
- number and pattern of mounting holes,
- shaft size,
- disc type,
- mounting system,
- exact dimensions,
- sealing design.
According to NTN-SNR recommendations, there are 3 quick and reliable identification methods.
1. Identification by reference number – the fastest method
Most AGRIHUB reference numbers are marked directly on the unit.
They are usually located:
- on the side,
- on the top,
- or underneath the disc.
If the reference number is readable, you can quickly check the compatible unit in a catalog or webshop. This is the easiest and safest identification method.
2. Identification by dimensions
If the reference number is damaged or no longer visible, technical dimensions can help identify the correct bearing unit.
The most important measurements are:
- number of holes,
- hole diameter,
- bolt circle diameter,
- main dimensions.
This method is especially useful for:
- older machines,
- heavily contaminated components,
- or worn bearing units.
3. Identification based on machine data
Compatibility can also be determined using the machine’s specifications.
Usually, the following information is sufficient:
- machine brand,
- model,
- shaft size,
- disc type,
- mounting system.
Using this data makes it easier to select the correct AGRIHUB unit quickly.
