Engineering Design Features
1. Agricultural Sealing System for Maximum Contamination Protection
Bearing contamination is one of the leading causes of agricultural equipment failure.
The WIR210-31 uses an agricultural sealing design to protect internal components from:
✔ Soil particles
✔ Dust intrusion
✔ Mud contamination
✔ Moisture exposure
✔ Fertilizer-related corrosion risks
The improved sealing structure helps maintain grease retention and supports longer operation intervals.
2. Spherical Outer Ring for Self-Alignment Capability
Agricultural machinery rarely operates under perfect alignment conditions.
During field operation, equipment frames may experience:
- Mechanical deformation
- Vibration
- Uneven loading
- Installation variation
The spherical outer ring allows the bearing to compensate for minor misalignment, helping maintain stable load distribution and reduce abnormal wear.
3. Reinforced Raceway for Shock Load Applications
Disc harrows and tillage equipment experience continuous impact forces.
The WIR210-31 is designed for:
- Rocky farmland
- Heavy soil conditions
- High-resistance cultivation
- Long working cycles
The hardened raceway improves resistance against:
- Raceway fatigue
- Impact damage
- Premature wear
4. Factory Lubrication for Reduced Maintenance
Each bearing is supplied with factory-filled grease to provide:
- Stable lubrication performance
- Reduced maintenance requirements
- Improved contamination resistance
- Easier installation
