Product Overview: The 31306 Tapered Roller Bearing
The 31306 bearing is a single-row tapered roller bearing from our robust 31300 Series, designed to handle heavy combined radial and axial loads. With key dimensions of 30x72x19mm, this bearing is engineered for precision and durability. Its unique construction, featuring a separable inner ring with a roller and cage assembly (cone) and an outer ring (cup), allows for easy mounting and adjustment. The tapered geometry of the rollers and raceways creates a design that is ideal for applications where both radial and axial forces are present, such as in gearboxes and axle systems. As a key component in our extensive line of Tapered Roller Bearings, the 31306 provides exceptional performance and reliability in demanding industrial and automotive environments.
Key Features of the 31306 Bearing
- High Load Capacity: Designed to accommodate high combined (radial and axial) loads in one direction.
- Separable Design: The cone (inner ring, rollers, cage) and cup (outer ring) are separable, simplifying mounting, dismounting, and maintenance inspections.
- Tapered Geometry: The roller and raceway contact lines meet at a common point on the bearing axis to provide true rolling motion and low friction.
- Adjustable Clearance: Can be mounted in pairs to handle axial loads in both directions and allows for the setting of a specific axial or radial clearance.
- Durable Construction: Manufactured from high-quality, high-carbon chromium bearing steel for enhanced durability and long service life.
- Logarithmic Profile: The roller profile is designed to optimize stress distribution along the contact length, preventing stress peaks and increasing bearing life.
Common Applications of 31306 Bearings
- Automotive Transmissions: Used in gearboxes and differentials to support shafts and gears.
- Wheel Hub Assemblies: Commonly found in the wheel hubs of cars, trucks, and trailers.
- Industrial Gearboxes: Provides robust support for shafts in various industrial reduction gears.
- Axle Systems: Ideal for use in axles of agricultural and construction machinery.
- Machine Tool Spindles: Ensures the precision and rigidity required for lathe and milling machine spindles.
- Rolling Mills: Employed in heavy-duty applications within steel and other material processing plants.
- Pumps and Compressors: Supports rotating shafts, ensuring reliability under heavy loads.
