Product Overview: The 387A/382 Inch Tapered Roller Bearing
The 387A/382 is a single-row Inch Tapered Roller Bearing set, comprising the 387A cone and the 382 cup. With a bore diameter of 57.15mm, an outer diameter of 101.6mm, and a total width of 30.163mm, this bearing is engineered to handle substantial combined radial and axial loads in one direction. Its two-part, separable design simplifies mounting and allows for precise adjustment of internal clearance during installation.
As a key component in our Tapered Roller Bearings collection, the 387A/382 is manufactured to stringent industry standards to ensure reliability and longevity. The tapered geometry of the rollers and raceways creates a true rolling motion, minimizing friction and heat generation under load. This design makes it an ideal choice for a wide range of demanding industrial and automotive applications where high load capacity and durability are essential.
Key Features of the 387A/382 Bearing
- Two-Part Separable Design: The cone (inner ring assembly) and cup (outer ring) can be mounted independently, facilitating easier installation and maintenance.
- High Load Capacity: Designed to accommodate heavy radial and single-direction axial (thrust) loads simultaneously.
- Tapered Roller Geometry: Reduces friction and ensures smooth, efficient operation by creating true rolling motion.
- Precision Manufacturing: Built to precise inch-based dimensions for consistent performance and interchangeability.
- Durable Construction: Made from high-quality, case-hardened bearing steel for superior wear resistance and extended service life.
- Adjustable Clearance: The separable design allows for setting the operational clearance to meet specific application requirements.
