The W211PPB3 agricultural disc harrow bearing is designed for OEM agricultural machinery operating in high contamination, heavy shock load, and misalignment-prone environments.
It is commonly used as a replacement bearing for disc harrow and tillage equipment applications, where installation fit, sealing performance, and structural stability are critical procurement factors.

Structural Design Features
1. Triple-Lip Sealing System (FKM / NBR Options)
The W211PPB3 uses a multi-stage sealing design to improve resistance against:
- Mud intrusion in wet soil fields
- Dust and abrasive particles
- Water and fertilizer contamination
Seal material selection depends on operating temperature and moisture level.
2. Spherical Outer Raceway (Self-Alignment Capability)
Designed to accommodate:
- Shaft misalignment
- Frame deformation during tillage
- Dynamic vibration under field load
Reduces uneven load distribution on raceway surfaces.
3. Reinforced Raceway for Shock Load Conditions
Optimized for:
- Rocky soil impact
- High-speed disc rotation
- Repeated cyclic agricultural loading
4. Grease Retention System
Factory pre-filled lubrication designed to:
- Maintain stable lubrication film
- Reduce maintenance frequency
- Improve contamination resistance
Application Scope
W211PPB3 is widely used in:
- Disc harrows (offset / tandem / heavy-duty)
- Cultivators and soil preparation equipment
- Ploughing machinery systems
- Seedbed preparation machines
- Agricultural tillage equipment OEM assemblies
- Replacement bearing programs for farm machinery fleets
Replacement & Compatibility Notice
W211PPB3 can be supplied as an aftermarket replacement option for equivalent W-series agricultural insert bearing applications.
Before replacement, buyers should confirm:
- Bore diameter
- Outer diameter
- Width dimensions
- Locking structure type
- Seal configuration
- Shaft and housing tolerance
This ensures correct installation and prevents premature failure caused by mismatched fit.
Performance Positioning (No Fixed Lifetime Claims)
Compared with standard single- or double-lip agricultural insert bearings, W211PPB3 is designed to provide:
- Improved resistance to contamination ingress
- More stable performance under shock load conditions
- Better lubrication retention in dusty and muddy environments
Actual service life depends on:
shaft condition, housing fit, operating speed, soil moisture, lubrication maintenance, and field conditions.
W211PPB3 vs W210PPB3 vs W209PPB3
| Model | Duty Level | Structure | Application |
|---|---|---|---|
| W209PPB3 | Light duty | Standard seal | Basic tillage systems |
| W210PPB3 | Medium duty | Improved sealing | General agricultural machinery |
| W211PPB3 | Heavy duty | Reinforced + triple-lip seal | Severe shock + high contamination environments |
Recommended upgrade path for high-load disc harrow applications.
Procurement Selection Guide (Important Section)
When to choose W211PPB3 instead of W210PPB3?
- Frequent bearing failure in muddy fields
- High impact or rocky soil conditions
- Excessive vibration during operation
- Short grease life cycle in current equipment
Seal Material Selection
- NBR seal → general farming, moderate temperature
- FKM seal → high temperature, fertilizer exposure, heavy moisture conditions
OEM & Distributor Stock Strategy
- W209PPB3 → high turnover, low cost replacement
- W210PPB3 → standard OEM fleet supply
- W211PPB3 → heavy-duty premium market / failure-sensitive applications
