FAW J6 Single Row Tapered Roller Bearing CL 30314/YB2 ZWZ
FUNCTION
1. Accommodates Combined Loads: Capable of simultaneously supporting substantial radial loads and unidirectional axial loads. The tapered roller structure distributes the load across an extensive contact line between the rollers and the raceway; consequently, its load-carrying capacity significantly exceeds that of standard ball bearings, making it ideally suited for heavy-duty vehicles.
2. Supports Rotating Components and Maintains Precise Alignment: In heavy-duty truck axle shafts, wheel hubs, or axles, these bearings facilitate the smooth rotation of the shaft while simultaneously limiting axial displacement, thereby ensuring that the wheel hub or axle shaft maintains a stable position during high-speed rotation.
3. Minimizes Friction and Transmission Losses: Featuring a low-friction design, these bearings-when utilized in conjunction with lubricating oil or grease-effectively reduce rotational resistance, enhance transmission efficiency, and minimize both energy loss and heat generation.
Working Principle
1. Separable Structure: Composed of an inner ring (cone with roller assembly), an outer ring (cup), and a cage. During installation, the inner ring fits onto the shaft, while the outer ring fits into the hub or axle housing; the rollers roll along the tapered raceway surfaces.
2. Line Contact Design: The rollers and raceways feature a line contact configuration, which effectively distributes heavy loads and provides superior resistance to shock and vibration.
3. YB2 Enhanced Version: The Wafangdian Bearing (ZWZ) YB2 variant typically incorporates designs featuring enhanced internal clearance or optimized precision. This further improves impact resistance and service life, having been specifically optimized to withstand the harsh operating conditions encountered by commercial vehicles.
Advantages
| No. | Performance Advantage Category | Detailed Description |
|---|---|---|
| 1 | High Load Carrying Capacity | Features a tapered roller line-contact design that can simultaneously withstand large radial loads and unidirectional axial loads. It has a high dynamic load rating (approx. 223,000–251,000 N), making it ideal for heavy-duty applications such as truck axle shafts and wheel hubs - far superior to ordinary ball bearings. |
| 2 | Long Service Life and High Reliability | YB2 enhanced version with optimized clearance and precision. Made of high-carbon chromium bearing steel (GCr15) with special heat treatment, offering excellent wear resistance, fatigue resistance, and impact resistance. Significantly extends service life under heavy load and bumpy road conditions, reducing early failure. |
| 3 | Low Friction and High Transmission Efficiency | Optimized raceway and roller surfaces result in a low friction coefficient, minimal heat generation, and high rotational accuracy. When used with proper grease or oil, it reduces transmission losses and improves vehicle power efficiency and fuel economy. |
| 4 | Convenient Installation and Maintenance | Separable structure (inner ring assembly and outer ring can be installed separately), making disassembly, assembly, and clearance adjustment easier. The YB2 version offers excellent compatibility in heavy truck axle shaft applications, reducing repair time and cost. |

During installation, it is recommended to inspect the axle shaft journal and bearing seat for any signs of wear or scratches; if any are found, they must be repaired or replaced.
It is recommended to inspect and/or replace both the left and right axle shaft bearings simultaneously. The installation orientation must be correct (with the larger ends of the rollers facing the load-bearing side). Striking the bearing directly with a hammer is strictly prohibited.
