R196Z-4 Tapered Roller Bearing For Excavator / Construction Equipment
The R196Z-4 tapered roller bearing is specifically engineered for heavy-duty construction machinery, particularly excavators. Designed to withstand extreme operating conditions, this bearing delivers exceptional stability, reliability, and longevity in demanding applications.
| Dimension | Value | Benefit |
|---|---|---|
| Inner Diameter | 196.85mm | Precise shaft fit for stable power transmission under high torque and impact forces |
| Outer Diameter | 241.3mm | Optimal load distribution and enhanced structural integrity |
| Width | 23.812mm | Balanced axial load capacity within compact installation space |
High-quality GCr15 chromium steel with hardness up to HRC60-65 after heat treatment. Provides exceptional wear resistance and fatigue strength for extended service life.
Available in high-strength steel for maximum durability or engineering plastics with self-lubricating properties for reduced friction and noise control.
Capable of handling both radial and axial loads simultaneously. Straight contact line design ensures uniform pressure distribution and reduces stress concentration.
Increased number of tapered rollers distributes loads more evenly, significantly enhancing load capacity and operational reliability under extreme conditions.
- High Load Capacity: Handles continuous heavy-load operations and sudden impact loads with stability
- Excellent Rotational Accuracy: Precision manufacturing ensures smooth operation with minimal vibration and noise
- Extended Service Life: Superior materials and design provide significantly longer operational life than standard bearings
- Excavator Traveling Mechanism: Provides reliable mobile support across varied terrain conditions
- Slewing Devices: Ensures precise 360-degree rotation accuracy for digging and material handling operations
- Other Construction Machinery: Suitable for loaders, bulldozers, and other heavy equipment requiring high-performance bearings
The R196Z-4 bearing delivers reliable performance in harsh environments including high temperatures, heavy pressures, and dusty conditions, making it an ideal choice for demanding construction applications.
