Product Overview: The 31303 Tapered Roller Bearing
The 31303 Tapered Roller Bearing is a robust, single-row bearing designed to handle high combined (radial and axial) loads in one direction. With key dimensions of 17mm Bore Diameter, 47mm Outer Diameter, and 15.25mm Thickness, this component is a staple in a wide range of demanding industrial and automotive applications. As part of our 31300 Series, the 31303 bearing features a separable design, with the inner ring and roller assembly (cone) mountable separately from the outer ring (cup). This facilitates easier installation, removal, and maintenance. Its tapered geometry ensures true rolling motion and low friction, contributing to operational efficiency and extended service life. Explore our full range of Tapered Roller Bearings to find the perfect solution for your heavy-duty needs.
Key Features of the 31303 Bearing
- Combined Load Capability: Engineered to accommodate significant radial and axial loads simultaneously in one direction.
- Separable Design: The cone (inner ring, rollers, cage) and cup (outer ring) can be mounted independently, simplifying the assembly process.
- High Load Capacity: The unique tapered design provides a large contact area, allowing for superior load-carrying capabilities compared to ball bearings of similar size.
- Low Friction Operation: Precision manufacturing and optimized geometry minimize rolling friction, reducing heat generation and energy consumption.
- Durable Construction: Manufactured from high-quality, case-hardened bearing steel for exceptional durability and resistance to wear and fatigue.
- Axial Load Management: Typically mounted in opposing pairs to effectively manage axial loads in both directions.
