Product Overview: The 30308 Tapered Roller Bearing
The 30308 bearing is a high-performance single-row tapered roller bearing, a key component in our 30300 Series and broader Tapered Roller Bearings collection. With principal dimensions of 40mm bore diameter, 90mm outer diameter, and a 25.25mm width, this bearing is engineered to manage heavy combined loads. Its unique design, featuring conical rollers and raceways, allows it to accommodate both radial and axial forces in one direction, making it exceptionally versatile for demanding industrial and automotive applications.
The 30308's construction includes a separable cup and cone assembly, which simplifies the mounting and maintenance process. This design ensures precise shaft guidance and high rigidity, contributing to the longevity and reliability of the machinery it's part of. As a premier supplier of industrial components, we guarantee our 30308 bearings meet stringent quality standards for optimal performance.
Key Features of the 30308 Bearing
- Combined Load Capacity: Expertly designed to handle substantial radial and single-direction axial loads simultaneously.
- Separable Design: The inner ring (cone) and outer ring (cup) are separable, allowing for easier installation, inspection, and maintenance.
- High Rigidity: Provides a rigid bearing application, crucial for machinery requiring precise rotational accuracy.
- Logarithmic Roller Profile: Reduces edge stress at the roller/raceway contact, increasing durability under heavy and shock loads.
- Low Friction Operation: Optimized internal geometry minimizes friction and heat generation, leading to improved efficiency and longer service life.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional wear resistance and strength.
