Product Overview: The 30221 Tapered Roller Bearing
The 30221 Tapered Roller Bearing is a high-performance component engineered to handle significant radial and axial loads simultaneously. With a bore diameter of 105mm, an outer diameter of 190mm, and a thickness of 39.75mm, this bearing is part of our extensive 30200 Series within the Tapered Roller Bearings category. Its design features tapered inner and outer ring raceways and tapered rollers, allowing it to accommodate combined loads and provide true rolling motion, which minimizes operational friction.
As a leading supplier of industrial and mechanical parts, we ensure that our 30221 bearings meet stringent quality standards for reliable performance in demanding environments. The separable design, consisting of a cone (inner ring with roller assembly) and a cup (outer ring), simplifies installation, removal, and maintenance procedures. This makes it an ideal choice for a wide array of heavy-duty applications across various industries.
Features of the 30221 Bearing
- Combined Load Capacity: Expertly designed to manage both high radial and axial (thrust) loads in one direction.
- Separable Components: The cone and cup can be mounted independently, which simplifies assembly and maintenance.
- High Rigidity: Provides excellent support for rotating shafts, enhancing the stability and precision of the entire assembly.
- Reduced Friction: The tapered geometry ensures true rolling motion, minimizing heat generation and energy loss.
- Durable Construction: Manufactured from high-quality bearing steel for superior strength, hardness, and service life under heavy loads.
- Adjustable Clearance: The axial clearance can be precisely set during mounting to optimize performance for specific applications.
Applications of 30221 Bearings
- Automotive Axles: Commonly used in vehicle wheel hubs, differentials, and pinion applications.
- Industrial Gearboxes: Provides robust support for gears and shafts in heavy-duty transmission systems.
- Agricultural Machinery: Essential for axles, wheels, and gear systems in tractors, harvesters, and other farm equipment.
- Construction Equipment: Found in the wheels and gearboxes of excavators, loaders, and bulldozers.
- Rolling Mills: Used in steel and metal processing machinery to support rollers under extreme pressure.
- Mining and Quarrying Equipment: Ideal for crushers, conveyors, and other heavy machinery operating in harsh conditions.
- Pumps and Compressors: Supports rotating elements in industrial pumps that handle high loads.
Benefits of Using the 30221 Bearing
- Enhanced Machine Performance: The ability to handle combined loads improves the overall efficiency and reliability of machinery.
- Extended Service Life: High load-carrying capacity and low-friction operation reduce wear and tear, leading to a longer operational lifespan.
- Reduced Maintenance Costs: The durable design and simplified mounting process minimize downtime and repair expenses.
- Improved Load Distribution: The line contact between rollers and raceways ensures even stress distribution, preventing premature failure.
- Operational Versatility: Suitable for a wide range of speeds and operating conditions in various heavy-duty sectors.
- Increased System Rigidity: By preloading a pair of tapered roller bearings, the rigidity of the application can be significantly increased.
