AGRIHUB SNR is the latest development from NTN. A bearing unit designed specifically for disc harrows: maintenance-free, 8-lip seal, forged steel housing, galvanized surface and pre-lubricated, sealed design.
AGRIHUB SNR is designed from real field experience
Previous NTN-SNR AGRIHUB units have earned their reputation. With the new AGRIHUB SNR HUA151 family, engineers went back to where these hubs actually live: dust, mud, water, vibration, stones, and manure. This generation isn’t just better on paper — it’s built for the field.
8-lip sealing — the defense against mud and dust
The headline upgrade is the sealing system. Instead of 4–6 lips, the new AGRIHUB uses a full 8-lip barrier on the contaminated side. Each lip plays a role — deflecting dust, repelling water, stabilizing internal grease — forming a multi-stage labyrinth that keeps contaminants out and lubrication stable. The design is intended to withstand high-pressure washdowns without internal contamination.
Forged steel housing with zinc coating
Field hubs take a beating: stones, shocks, water jets, fertilizers. That’s why the new AGRIHUB housing is forged steel with extra wall thickness rather than cast or pressed. It absorbs impact before it reaches the bearing races and shields the sealing zone from deformation. The zinc coating adds robust corrosion resistance in moisture- and manure-rich environments.
Factory-sealed, maintenance-free
Every AGRIHUB is factory-greased and permanently sealed. No re-lubrication, no over-greasing, no seal damage from pressure spikes. The internal grease is formulated for agricultural duty cycles, resisting heat and shear to protect through multiple seasons.
Compatibility and drop-in fit
The HUA151 series comes in 4-, 5- and 6-bolt patterns and is widely interchangeable with popular Agri Hub standards on the market. In practice, that means straightforward installation: bolt patterns and interfaces line up — while sealing performance and housing robustness take a step up.

Why upgrade to ANGIHUB SNR? A quick comparison..
| Feature | Previous NTN-SNR Agri Hub | New SNR AGRIHUB |
|---|---|---|
| Sealing | 4–6 lips (model-dependent) | 8-lip, multi-stage labyrinth |
| Housing | Cast / pressed steel | Forged steel, zinc-coated |
| Lubrication | Re-greasing possible | Factory-sealed, maintenance-free |
| Drop-in fit | Limited interchangeability | Broad interchangeability |
What this means in the field
When a harrow runs 10–12 hours a day, any bearing failure costs time, money, and peace of mind. The new AGRIHUB SNR takes that worry off your shoulders. Install it once — and it just keeps working.

FAQ – AGRIHUB SNR
What is the AGRIHUB SNR and what is it for?
A maintenance-free Agri Hub bearing unit for disc harrows. It is factory-greased and sealed, engineered to resist dust, mud, and water ingress in agricultural environments.
How is the new generation different from the previous NTN-SNR AGRIHUB?
The new AGRIHUB adds an 8-lip sealing system on the contaminated side, a forged, thick-wall steel housing, and a zinc-coated finish to boost contamination resistance and impact robustness.
Does the AGRIHUB require re-greasing?
No. The unit is factory-sealed and maintenance-free, eliminating the need for re-lubrication and the risks associated with over-greasing.
Is it interchangeable with other brands’ Agri Hub units?
The HUA151 series in 4-, 5- and 6-bolt versions is broadly interchangeable with common market standards, thanks to matching bolt patterns and interfaces.
What environments is the AGRIHUB optimized for?
Agricultural harsh duty: dust, mud, water, vibration, stones, and manure. The sealing and housing design specifically target these stressors.
Which versions are available?
The HUA151 series in 4-, 5-, and 6-bolt configurations for disc harrows. Detailed sizing and compatibility are available on the product page.
