Product Overview: The 31309 Tapered Roller Bearing
The 31309 Tapered Roller Bearing is a robust and reliable component designed to handle heavy combined loads. As part of our comprehensive Tapered Roller Bearings collection and the specialized 31300 Series, this bearing features a unique design with tapered inner and outer ring raceways and tapered rollers. This geometry allows the bearing to accommodate simultaneous radial and axial loads in one direction, making it exceptionally versatile for demanding industrial and automotive applications. The standard dimensions for the 31309 are a 45mm bore diameter, 100mm outer diameter, and a 38.25mm thickness.
A key feature of the 31309 bearing is its separable design. The inner ring with the roller and cage assembly (the cone) can be mounted separately from the outer ring (the cup). This separation simplifies installation, removal, and maintenance procedures, offering significant practical advantages in complex machinery. Our commitment to quality ensures that every 31309 bearing meets stringent industry standards for performance and longevity.
Key Features of the 31309 Bearing
- Combined Load Management: Expertly designed to handle high radial and axial (thrust) loads in a single direction.
- Separable Components: The cone (inner ring, rollers, cage) and cup (outer ring) are mountable separately, simplifying installation and inspection.
- High Load-Carrying Capacity: The line contact between rollers and raceways allows for greater load distribution and superior capacity.
- Reduced Friction Design: Precision engineering minimizes friction and heat generation, leading to improved operational efficiency and a longer service life.
- Durable Construction: Manufactured from high-quality, case-hardened bearing steel for exceptional durability and resistance to wear and fatigue.
- Axial Load Support: Particularly effective in applications that require robust support against thrust forces.
