Product Overview: The 31308 Tapered Roller Bearing
The 31308 bearing is a high-performance, single-row tapered roller bearing designed to withstand heavy combined (radial and axial) loads. As a key component in our 31300 Series of Tapered Roller Bearings, it features a separable design, with the inner ring and roller assembly (cone) and the outer ring (cup) being mountable independently. This design simplifies installation, inspection, and maintenance procedures. The tapered geometry of the rollers and raceways creates a true rolling motion and low friction, making it an essential component for demanding industrial and automotive applications.
With its principal dimensions of 40x90x25.25mm, the 31308 is engineered for reliability and a long service life. Its construction allows it to accommodate axial loads in one direction, and it is often mounted in pairs (back-to-back or face-to-face) to handle axial loads in both directions. We are a leading supplier committed to providing high-quality, industry-standard mechanical parts for all your machinery needs.
Features of the 31308 Bearing
- Separable Design: The cone (inner ring, rollers, cage) and cup (outer ring) can be mounted separately, simplifying assembly and maintenance.
- High Load Capacity: Engineered to handle significant combined radial and axial loads, making it suitable for heavy-duty applications.
- Single-Direction Axial Load: Designed to accommodate axial loads in one direction. Often used in pairs for bi-directional support.
- Low Friction Operation: The tapered design ensures true rolling motion between rollers and raceways, minimizing friction and heat generation.
- Precision Manufacturing: Produced from high-quality bearing steel to strict industry standards, ensuring dimensional accuracy and consistent performance.
- Durability and Reliability: Robust construction provides excellent resistance to wear and fatigue, ensuring a long operational life.
