Product Overview: The 31311 Tapered Roller Bearing
The 31311 bearing is a single-row tapered roller bearing designed to handle heavy combined radial and axial loads. As a key component in our Tapered Roller Bearings collection, this bearing belongs to the versatile 31300 Series. Its principal dimensions are a 55mm bore diameter, a 120mm outer diameter, and a 31.5mm total width. The design features a separable cone (inner ring, rollers, and cage) and cup (outer ring), which simplifies mounting, dismounting, and inspection procedures. The tapered geometry of the rollers and raceways creates a contact angle that allows the bearing to effectively manage simultaneous loads, making it a reliable choice for a wide range of demanding industrial and automotive applications.
Key Features of the 31311 Bearing
- Separable Design: The cone and cup assemblies can be mounted independently, simplifying installation and maintenance.
- Combined Load Capacity: Engineered to accommodate high radial and axial loads in a single direction.
- High-Quality Material: Constructed from premium-grade bearing steel for exceptional durability and a long operational lifespan.
- Low-Friction Operation: The logarithmic roller profile reduces edge stresses and ensures smooth, efficient rotation.
- Precision Engineering: Manufactured to strict tolerances for reliable and consistent performance in demanding conditions.
- Axial Load Versatility: The contact angle is optimized to handle significant axial forces, making it suitable for various load configurations.
