3x longer field life than standard FD211RB. Fully interchangeable. Engineered for dust, mud, fertilizer, and heavy impact.
The Problem – Why Standard Bearings Fail Too Fast
In demanding agricultural environments, disc harrow bearings must withstand:
- Abrasive dust and dry soil
- Mud, moisture, and chemical fertilizers
- Heavy impact loads from rocks and uneven ground
Standard bearings like FD211RB often fail in under 400 hours, leading to downtime, shaft damage, and costly mid-season replacements.
The Solution – ST740 Agricultural Bearing Assembly
The ST740 is engineered specifically for harsh field conditions. It delivers reliable performance where standard bearings fail.
Fully interchangeable with:
DHU2-3/16R-211 · FD211RBA · ST740B · FD211RB
No modification required. Direct bolt-on replacement.
ST740 vs Standard FD211RB
| Feature | Standard FD211RB | ST740 (Upgraded) |
|---|---|---|
| Seal Type | Single Lip | Triple Lip (IP66-level) |
| Steel Grade | Standard Chrome | GCr15 Precision Ground |
| Housing Strength | Class 30 Iron | Class 40 / Ductile Iron |
| Field Life | ~400 hours | 1200+ hours |
| Interchange | Limited | Direct Bolt-On |
The difference is not just specs — it's hundreds of hours of reliable operation.
