Product Overview: The 30218 Tapered Roller Bearing
The 30218 Tapered Roller Bearing is a robust, single-row bearing designed to manage high radial and axial loads in a single direction. With a bore diameter of 90mm, an outer diameter of 160mm, and a thickness of 42.5mm, this bearing is a key component in a wide range of demanding industrial and automotive applications. As part of our extensive Tapered Roller Bearings collection and the 30200 Series, the 30218 features a separable design, with the inner ring (cone) and outer ring (cup) being mountable separately. This characteristic simplifies installation, maintenance, and inspection processes.
The unique geometry of tapered rollers allows for true rolling motion and low friction, ensuring efficient operation and a long service life even under heavy loads. These bearings are typically mounted in pairs in a back-to-back or face-to-face arrangement to accommodate axial loads in both directions. We are a trusted supplier of high-quality industrial components, providing reliable bearings like the 30218 for critical machinery across various sectors.
Key Features of the 30218 Bearing
- High Load Capacity: Engineered to support substantial combined (radial and axial) loads.
- Single-Direction Axial Load: Effectively handles axial loads in one direction. For bidirectional support, they are used in pairs.
- Separable Design: The cone (inner ring with roller assembly) and cup (outer ring) can be mounted independently, facilitating easier installation and maintenance.
- Low Friction: The tapered roller design ensures low friction during operation, reducing heat generation and energy consumption.
- Dimensional Stability: Manufactured from high-quality bearing steel for superior hardness, wear resistance, and durability under load.
- Precise Roller Guidance: The flange on the inner ring guides the rollers, ensuring proper alignment and stability.
Common Applications of 30218 Bearings
- Automotive Systems: Widely used in vehicle wheel hubs, transmissions, and differentials.
- Industrial Gearboxes: Provides reliable support for gears and shafts in heavy-duty gear reducers.
- Agricultural Machinery: Essential for equipment such as tractors, harvesters, and implements that operate under harsh conditions.
- Construction Equipment: Found in heavy machinery like cranes, excavators, and bulldozers.
- Axle Assemblies: Ideal for supporting axles in trucks, trailers, and railway vehicles.
- Rolling Mills: Used in steel and metal processing machinery to handle extreme loads.
- Mining and Quarrying Equipment: Supports components in crushers, conveyors, and other heavy-duty machinery.
