Product Overview: 387AS/382A Inch Tapered Roller Bearing
The 387AS/382A is a single-row inch series Tapered Roller Bearing, a crucial component for applications requiring robust support for combined radial and axial loads. This bearing set, with key dimensions of 53.975mm bore diameter, 98.425mm outer diameter, and 30.163mm total width, consists of two separable parts: the cone assembly (inner ring, rollers, and cage), designated as 387AS, and the cup (outer ring), designated as 382A. The tapered geometry of the rollers and raceways ensures true rolling motion, minimizing friction and wear while efficiently managing high loads. This design is particularly effective in handling significant axial forces in one direction.
As a specialist supplier of industrial and automotive parts, we offer high-quality Inch Tapered Roller Bearings like the 387AS/382A, manufactured to precise industry standards for optimal performance and durability. Its separable design simplifies installation, removal, and maintenance procedures, making it a preferred choice for a wide array of machinery.
Key Features of the 387AS/382A Bearing
- Two-Part Assembly: Consists of a separable cone (387AS) and cup (382A), allowing for easier mounting and inspection.
- Inch Series Design: Manufactured to standard inch dimensions, ensuring compatibility with a wide range of North American and specialized equipment.
- High Load Capacity: Engineered to accommodate heavy radial and axial (thrust) loads in a single direction.
- Tapered Raceways: The design ensures pure rolling motion, which reduces operational friction and heat generation, leading to a longer service life.
- Durable Construction: Made from high-carbon chromium bearing steel for exceptional hardness, wear resistance, and longevity under demanding conditions.
- Versatile Application: Suitable for a broad spectrum of industrial, automotive, and agricultural machinery.
Common Applications of 387AS/382A Bearings
- Automotive Systems: Widely used in vehicle wheel hubs, transmissions, and differentials where high loads are common.
- Agricultural Machinery: Ideal for implements such as cultivators, seeders, and harvester components that operate in harsh environments.
- Construction Equipment: Found in gearboxes, axles, and rollers of heavy machinery like loaders and bulldozers.
- Industrial Gearboxes: Provides reliable support for gears and shafts, ensuring smooth power transmission.
- Trailer and Axle Assemblies: Commonly used in trailer wheels and axle systems to support heavy cargo loads.
- Mining and Quarrying Equipment: Suitable for conveyor belt rollers and other machinery subjected to heavy, continuous operation.
- Machine Tool Spindles: Offers the precision and rigidity required for high-accuracy machining applications.
Benefits of Using the 387AS/382A Bearing
