Precision 30206 Tapered Roller Bearing For Construction Machinery

30206 Tapered Roller Bearing: High Load & Precision Performance

I. Product Overview​

As an important component in mechanical transmission systems, the 30206 tapered roller bearing provides solid support for the stable and efficient operation of various mechanical equipment with its meticulously designed structure and excellent performance. It can bear large radial loads and unidirectional axial loads simultaneously, performing outstandingly in working conditions with high requirements for bearing capacity and running accuracy. It is widely used in multiple industries such as automobiles, machine tools, heavy machinery, and agricultural machinery, and is a core component ensuring the stable operation of key equipment parts and efficient power transmission.​

II. Structural Design​

1. Precise Cooperation between Rollers and Raceways: The 30206 tapered roller bearing is equipped with frustum-shaped rollers inside, which are precisely guided by the large rib of the inner ring. The vertices of the conical surfaces of the inner ring raceway surface, outer ring raceway surface, and roller rolling surface cleverly converge at the same point on the bearing's center line, enabling the rollers to achieve pure rolling on the raceway surfaces. When the equipment is running under complex loads, force balance is achieved through the combined force of the inner and outer ring raceway surfaces and the interaction between the large rib of the inner ring and the rollers, effectively dispersing stress, ensuring smooth operation of the bearing, reducing wear, and prolonging service life.​

2. Separable Inner and Outer Ring Structure: The design of separable inner ring assembly and outer ring greatly facilitates installation and maintenance. During installation, the inner ring and outer ring can be operated separately, and the axial and radial clearances can be flexibly adjusted to adapt to different working conditions. Both the inner and outer rings can be installed with interference fit to ensure close fit with the shaft and bearing housing during high-load operation, avoiding loosening and improving the running accuracy and stability of the equipment.​

IV. Performance Advantages​

1. Strong Bearing Capacity: The unique design of rollers and raceways results in a large contact area, which can efficiently disperse loads and bear large radial and unidirectional axial loads. For example, in automobile transmissions, it can stably bear complex radial and axial forces generated by gear transmission, ensuring efficient and reliable operation of the transmission and smooth power transmission.​

2. Excellent Rigidity and Accuracy Retention: The line contact between rollers and raceways gives higher rigidity compared to point-contact bearings. During operation, it can effectively suppress shaft deformation and vibration, maintaining high running accuracy. In the application of precision machine tool spindles, it can ensure precise cutting of tools, processing high-precision parts to meet the needs of precision machining.​

3. Good High-Speed Adaptability: After optimized design, it can adapt to high-speed operation within a certain speed range. By selecting high-quality materials, optimizing the structure, and adopting advanced manufacturing processes, internal friction and heat generation are reduced, ensuring stable operation at higher speeds, reducing wear and fatigue caused by high speeds, and prolonging service life.​

V. Application Fields​

1. Automobile Industry: Widely used in parts such as front wheels, rear wheels, transmissions, and differential pinion shafts of automobiles. At the wheels, it bears radial road forces during driving and axial forces generated by steering and braking, ensuring stable operation of the wheels; in transmissions and differentials, it copes with complex loads from gear transmission, ensuring efficient and smooth power transmission.​

2. Machine Tool Field: Suitable for machine tool spindles with high requirements for running accuracy and rigidity. It stably supports the spindle during high-speed cutting, ensuring precise positioning of tools, processing high-precision parts to meet the precision machining needs of the machinery manufacturing industry.​

3. Construction Machinery Field: It can bear huge radial and axial loads of construction machinery such as cranes and excavators during work, ensuring stable operation of key components, adapting to harsh environments and high-intensity operation requirements of construction sites, and ensuring smooth progress of projects.​

4. Agricultural Machinery Field: In large agricultural machinery such as tractors and combine harvesters, it can bear complex loads generated by terrain, soil and other factors during field operations, ensuring stable operation of the transmission system and facilitating efficient agricultural production.
