Hub Needle Roller Bearing with Sealing Ring

---

The hub needle roller bearing with a sealing ring is an advanced type of bearing designed to offer high performance and durability. It is specifically engineered to match the thickness of the plain bearing used in the active gearbox, making it a suitable replacement for traditional sliding bearings. This design allows for precise control of oil levels and quantities, ensuring optimal lubrication and performance similar to that of conventional sliding bearings. One of the key features of this bearing is the use of a thin-walled seal, which has a thickness of only 0.85 mm. This significantly reduces the overall thickness of the bearing section—from 3 to 3.5 mm down to just 1.5 mm. The thin seal helps optimize the clearance between the rotating shaft and the sealing ring, enabling better control over the internal oil flow and reducing leakage. This improvement enhances the bearing's ability to maintain proper lubrication under various operating conditions. In addition to its improved sealing capabilities, the hub needle roller bearing with a sealing ring also offers enhanced anti-fouling properties. This helps prevent damage caused by friction and wear, especially in low-speed rotation areas where collisions may occur. The design not only improves efficiency but also extends the service life of the bearing. Beyond its application in the active gearbox, this type of bearing can also be found in hybrid vehicles and other industrial sectors. Its versatility makes it a popular choice for engineers looking for reliable and efficient bearing solutions.
