In agriculture, uptime directly translates to output. Delays in fieldwork—especially during critical seasons—can result in lost yield, extra costs, or skipped planting windows. Bear in mind that bearings are often the costliest weak point in tillage attachments. That’s where SKF’s Agri Hub comes in: a sealed, pre-lubricated bearing assembly engineered for harsh-field performance.
🌾 What Is an Agri Hub and What Does It Do?
An Agri Hub is a bearing unit explicitly designed for tillage and seeding equipment used in agriculture—most commonly in disc harrows, vertical tillage machines, and cultivators.
Agri hubs connect the rotating disc blade to the machine’s frame, allowing it to spin freely while holding up under heavy loads, vibration, and contamination.
On a disc harrow or vertical tillage tool:
- Each disc blade spins independently.
- That disc is mounted on a shaft (spindle).
- The Agri Hub slides onto that shaft and is bolted to the disc arm or gang frame.
- It houses the bearing that allows the disc to rotate while supporting radial and axial forces (side-loads, bumps, vibrations).
🔍 Inside the SKF Agri Hub:
Unlike conventional bearing setups that require multiple components—bearing, housing, spacer, seals, and regular lubrication—the SKF Agri Hub integrates everything into one compact, maintenance-free, ready-to-install unit. It mounts directly onto the disc arm and is sealed for life, offering exceptional resistance to contamination, shock loads, and moisture.
- Double-row angular contact ball bearings: Handle both radial and axial loads from rough, high-speed fieldwork.
- Pre-lubricated bearing cavity: Filled with high-performance grease in a sealed, factory-controlled environment.
- Advanced sealing system: Multi-lip or labyrinth seals protect internal components from mud, stones, water, and chemical exposure.
- Integrated flange and housing: Reduces misalignment risks and simplifies installation.
- Ecological Zinc Layer Coating: This coating resists oxidation and allows cleaning with a high-pressure hose. The surface geometry is designed to prevent grasses, stems, and roots from getting entangled with the hub.
The end result? A rugged, long-life hub designed to outlast traditional assemblies by 3–5×, while eliminating the need for daily greasing and reducing the risk of breakdowns mid-season.
🎯 The Full-Season Solution
Traditional hubs typically require daily relubrication, take half an hour per day per machine, and can leak up to 130 gallons of grease over ten years, causing both environmental harm and downtime.
SKF Agri Hub units eliminate all that:
- Configured for 50 kha (T50) to 100 kha (T100) to 200 kha (T200) seasons—meaning 123,000–494,000 acres before replacement.
- 360° sealed for life—no lubrication, no leakage, quicker installation and replacement .
- 3–5× longer life than conventional bearings; exceptional sealing against mud, stones, and dust reduces contaminant ingress.
⏱️ Real-World Time & Money Savings
Time savings:
One farmer documented his experience comparing his old harrow with his new machine with the SKF agri hub:
- Eliminated 30 min/day spent cleaning and greasing.
- Field speeds rose from 4–5 mph (7-8 km/h) to over 12 mph (20 km/h), raising coverage from 1 to 2.5 ha/hr.
With his average of 40 tillage days per season, that’s over 20 hours saved on greasing and washing alone.
Cost and ROI:
SKF reports:
- Up to 30% reduction in total cost of ownership (TCO), factoring lower downtime, reduced relubrication, and fewer replacements and repairs.
- 130 gallons of grease per machine saved over 10 years—cutting supply spending and soil contamination.

🚜 Boosting Productivity: Field Evidence
- Farm A (USA): “We’ve pulled our Norwood Kwik-Till machine 11-12 mph through the field and so far have covered 8,000 acres with zero bearing failures. That is truly exceptional!” – Dan Norwood
- Farm B (Russia): 8,000 acres (~3,200 ha) covered with zero hub failures.

❓ What Farmers Want to Know About Agri Hubs
When considering an investment in Agri Hubs, most farmers and equipment operators ask a few common but critical questions. Note that many of these questions are difficult to answer with finality since there are so many variables, so many of the answers are example-based.
Let’s address these questions:
Q1: How long do Agri Hubs last compared to traditional bearing setups?
A: SKF Agri Hubs are rated for up to 494,000 acres of operation (T200 version). This equates to approximately 8–10 full seasons for large operations. Traditional hub assemblies often require replacement every 1–2 seasons, depending on conditions.
Q2: Are they really maintenance-free? How can a sealed bearing survive rough field conditions for that long?
A: Yes—completely maintenance-free. SKF achieves this with:
- A sealed, double-row bearing design to distribute loads evenly.
- Factory-sealed lubrication using long-life grease optimized for wide temperature ranges and high-impact shock.
- Advanced sealing that prevents entry of water, dust, or crop debris, even during high-pressure washdowns.
Lab and field tests have shown Agri Hubs can maintain integrity through high-speed discing in mud, frozen ground, and rock-strewn fields, without any relubrication or component degradation.
Q3: How much money will I actually save by switching?
A: Savings vary by operation size, but here’s a typical example:
- Grease savings: 130 gallons over 10 years (a 55-gallon drum of grease goes for about $2,600 if you are buying in bulk).
- Labor/time: Save ~30 minutes per day per machine greasing hubs = 20+ hours/season.
- Breakdown reduction: Less downtime during planting/harvest = less risk of yield loss or rework.
- Longer hub life: Replacing Agri Hubs every 7–10 seasons instead of every 1–2 seasons = a lot of labor saved replacing hubs.
Total TCO (total cost of ownership) is reduced by up to 30% over the life of the equipment.
Q4: Will these fit my current tillage equipment?
A: SKF Agri Hubs are designed for common configurations—both imperial and metric—making them compatible with a wide range of popular disc harrows and vertical tillage machines.
IBT can help you match the correct Agri Hub model to your specific equipment and even assist with cross-referencing part numbers.
Q5: What if I break a hub mid-season? Are these harder to replace?
A: Not at all. Replacement is incredibly fast:
- The Agri Hub is a single unit—just remove the nut, slide off the old hub, mount the new one.
- No packing, greasing, or multiple part alignment.
- Most replacements can be done in under 15 minutes in the field.
IBT can get you replacements quickly.
Q6: Is it worth the investment if I run smaller acreage or fewer machines?
A: Yes. While large-scale farms may see faster ROI, smaller operations benefit too:
- Less daily maintenance = more time for other work.
- More reliable machinery during critical planting/harvest windows.
- No need to train or remind workers to grease bearings.
For a modest premium, Agri Hubs offer peace of mind and hassle-free uptime.
