Product Overview: The 30312 Tapered Roller Bearing
The 30312 bearing is a single-row tapered roller bearing meticulously engineered to handle high combined radial and axial loads. As a key component in our 30300 Series of Tapered Roller Bearings, it features a unique design with tapered inner and outer ring raceways and tapered rollers. This geometry allows the bearing to accommodate significant radial forces and axial forces in one direction simultaneously. Its dimensions of 60mm Bore Diameter, 130mm Outer Diameter, and 33.5mm Thickness make it a robust choice for a variety of demanding industrial and automotive applications.
A notable feature of the 30312 is its separable design, where the inner ring with the roller and cage assembly (the cone) can be mounted separately from the outer ring (the cup). This simplifies installation, removal, and maintenance procedures, especially in complex machinery. Manufactured to precise industry standards, this bearing ensures reliable performance, reduced friction, and an extended operational lifespan in challenging environments.
Key Features of the 30312 Bearing
- Combined Load Capacity: Expertly designed to manage both high radial and axial loads in a single direction.
- Tapered Geometry: The conical shape of the rollers and raceways ensures true rolling motion and low friction.
- Separable Components: The cone and cup can be mounted independently, facilitating easier assembly and maintenance.
- High Rigidity: Provides a rigid bearing application, crucial for precision machinery like gearboxes and machine tool spindles.
- Durable Construction: Made from high-purity, hardened bearing steel for exceptional durability and wear resistance.
- Logarithmic Profile: The roller profile is optimized to prevent stress peaks at the roller ends, increasing service life.
