Modern agricultural machinery operates in extremely demanding environments. Bearings used in disc harrows and vertical tillage machines must withstand heavy radial loads, shock impact, dust, and soil contamination.
The AA28186 Agricultural Bearing is designed specifically for these conditions. With reinforced internal structure, advanced sealing protection, and optimized lubrication, it provides reliable performance for heavy-duty tillage equipment used in large-scale farming operations.
Cross Reference Part Numbers
To simplify equipment maintenance and replacement, the AA28186 agricultural bearing is interchangeable with several commonly used agricultural bearing references.
- GW211PPB20
- DS211TTR20
- AA28186
- AA30942
- AKK22197
These cross references allow distributors, service technicians, and equipment manufacturers to quickly match replacement parts without requiring machine modifications.

Why Choose Our AA28186 Over Generic Replacements?
While there are many bearings that claim to fit John Deere and Turbo-Till equipment, not all are built to withstand the actual torque and abuse of a 40,000-acre farming season. Our AA28186 isn't just a dimensional copy; it’s a metallurgical upgrade.
-
Thicker Raceways: Engineered to handle the specific shock loads of the 370 and 4000TT models.
-
Sealing Tested in Dust: We subject our seals to a fine silica dust test that simulates 1,000 hours of Nebraska field work.
Key Features of AA28186 Agricultural Bearing
1.Heavy-Duty Load Capacity
Disc harrow bearings experience constant radial load and shock impact when blades engage compact soil or rocks. The AA28186 bearing is built with reinforced raceways and precision steel balls to handle these conditions and maintain stable operation.
2.Advanced Multi-Lip Sealing Protection
Agricultural environments introduce dust, mud, and crop residue that can quickly damage bearings. The multi-lip sealing design prevents contaminants from entering the raceway while keeping grease inside the bearing.
3.Factory Pre-Lubricated Performance
Each AA28186 bearing is filled with high-performance agricultural grease designed for vibration resistance and long-term lubrication stability.
4.Shock Resistance for Rough Field Conditions
Disc blades frequently encounter rocks and uneven ground. The internal geometry of the bearing distributes these impact forces evenly, helping prevent raceway fatigue.
Typical Applications
The AA28186 agricultural bearing is commonly used in:
- Disc harrow gang assemblies
- Vertical tillage machines
- Soil preparation equipment
- Turbo-Till field cultivators
- Heavy-duty agricultural implements
These applications require bearings capable of operating continuously in environments with high contamination and heavy mechanical loads.
Quality Control and Manufacturing
Each AA28186 bearing undergoes strict manufacturing and inspection procedures to ensure consistent field performance.
- Raceway hardness testing
- Dimensional tolerance inspection
- Seal integrity verification
- Rotational smoothness testing
- Grease fill consistency inspection
