Using a standard industrial insert bearing may increase replacement frequency when the operating environment exceeds normal conditions.
WIR212-39 is designed around these agricultural application requirements.
Common Bearing Failure Risks and WIR212-39 Solutions
| Failure Risk | Purchasing Concern | WIR212-39 Design Advantage |
|---|---|---|
| Premature failure | Frequent replacement increases maintenance cost | Agricultural sealing structure helps protect internal components |
| Bearing movement | Loose mounting affects equipment operation | Extended inner ring with set screw locking improves shaft fixation |
| Uneven wear | Misalignment reduces bearing life | Spherical outer ring helps compensate minor alignment errors |
| Lubrication problems | Short maintenance intervals | Factory grease filling improves lubrication consistency |
| Supply inconsistency | Difficult aftermarket inventory management | Stable batch production supports continuous supply |
Engineering Features Designed for Agricultural Applications
Agricultural Sealing Structure
For disc harrow and tillage equipment, bearing contamination protection is an important factor affecting service life.
WIR212-39 sealing design helps:
- Improve protection against external contaminants
