Product Parameters
The Single Row Tapered Roller Bearing 30200 Series is designed for automotive axles, offering a balance of load capacity, durability, and efficiency. These bearings are characterized by their tapered rollers, which distribute loads evenly across the raceways, ensuring smooth operation and reduced friction. The 30200 series is specifically engineered to handle moderate to high radial loads while providing excellent axial load capacity in one direction.
Key parameters of the 30200 series include an outer diameter of 52mm, an inner diameter of 30mm, and a width of 16mm. The bearing’s contact angle is typically 12 degrees, which optimizes load distribution and performance. The material used for the rollers and raceways is high-quality steel, often case-hardened to enhance wear resistance. The raceways are ground to precise tolerances, ensuring optimal fit and function.
The bearing’s design also includes a lubrication system that minimizes the need for frequent maintenance. This is achieved through a retainer that keeps the rollers in place and prevents them from shifting during operation. The retainer is made of high-impact polymer or metal, depending on the application requirements. Additionally, the bearing’s seals are designed to protect against dust and moisture, extending its service life.
Typical Use Cases
The Single Row Tapered Roller Bearing 30200 Series is widely used in automotive applications, particularly in axles and wheel hubs. These bearings are ideal for vehicles that require high load capacity and smooth operation, such as trucks, SUVs, and commercial vehicles. They are also suitable for passenger cars, especially those used for heavy-duty purposes like towing or off-roading.
In these applications, the bearing supports the wheel hub, allowing for rotational movement while承受 radial and axial loads. The tapered roller design ensures that the load is evenly distributed, reducing the risk of premature failure. This makes the 30200 series a reliable choice for automotive manufacturers and maintenance professionals.
Another common use case is in agricultural machinery, where the bearing is used in drive shafts and gearboxes. The robust design of the 30200 series can handle the harsh conditions often found in agricultural environments, ensuring long-term reliability. Additionally, the bearing’s ability to operate in extreme temperatures makes it suitable for a wide range of climates and conditions.
Real-World Applications
One real-world application of the Single Row Tapered Roller Bearing 30200 Series is in a commercial truck used for long-haul transportation. The truck’s axles require bearings that can handle high radial loads and continuous operation. The 30200 series has proven to be reliable in this application, providing smooth operation and minimal maintenance. The truck’s maintenance team has reported that the bearings have lasted over 100,000 miles with only occasional lubrication.
Another example is a construction vehicle used for heavy-duty tasks such as digging and lifting. The vehicle’s wheel hubs are equipped with the 30200 series bearings, which have demonstrated excellent performance under extreme conditions. The bearings have withstood heavy loads and frequent use, ensuring the vehicle remains operational even in challenging environments. This has been a critical factor in the vehicle’s overall reliability and productivity.
Additionally, the bearing has been used in a passenger car that frequently carries heavy loads, such as grocery shopping or transporting children. The 30200 series has provided the necessary support for the wheel hubs, ensuring a smooth and safe ride. The car’s owner has noted that the bearings have required minimal maintenance, contributing to the vehicle’s overall longevity and performance.
Solutions for Common Issues
One common issue with tapered roller bearings is premature wear. This can be mitigated by ensuring proper lubrication and maintenance. The 30200 series is designed with a lubrication system that minimizes the need for frequent re-lubrication. However, it is still important to follow the manufacturer’s recommendations for lubrication intervals and types of lubricants used.
Another issue is the bearing’s ability to handle axial loads. While the 30200 series is designed to handle moderate axial loads in one direction, it is important to ensure that the bearing is installed correctly. Incorrect installation can lead to uneven load distribution, resulting in premature failure. It is crucial to follow the manufacturer’s installation guidelines and use the appropriate tools to ensure proper alignment and fit.
Additionally, contamination can be a significant issue for tapered roller bearings. Dust and moisture can enter the bearing and cause wear and tear. To prevent this, it is important to use seals that are designed to protect against contamination. The 30200 series comes with high-quality seals that are effective in most conditions. However, in extremely harsh environments, additional protective measures may be necessary.
