Product Overview: The 387/382A Tapered Roller Bearing
The 387/382A bearing is a high-performance, single-row Inch Tapered Roller Bearing designed for exceptional durability and reliability in demanding applications. With a bore diameter of 53.975 mm, an outer diameter of 92.075 mm, and a total width of 23.812 mm, this bearing is engineered to handle a combination of heavy radial and axial loads. Its design consists of two main separable parts: the cone (inner ring assembly) and the cup (outer ring), which allows for easier mounting and maintenance. The tapered geometry of the rollers and raceways creates a true rolling motion, minimizing friction and wear under load.
As a key component in our extensive range of Tapered Roller Bearings, the 387/382A is manufactured to precise industry standards. It is an essential part for various industrial and automotive systems where robust load support and precise rotational control are critical. This bearing's ability to manage combined loads makes it a versatile solution for gearboxes, axle assemblies, and heavy machinery.
Key Features of the 387/382A Bearing
- Separable Design: The cone (387) and cup (382A) can be mounted independently, simplifying installation, inspection, and maintenance procedures.
- Combined Load Capacity: Expertly designed to accommodate both heavy radial and thrust (axial) loads in one direction.
- Inch Series Standard: Manufactured to standard inch dimensions, ensuring interchangeability and suitability for a wide range of equipment.
- High Rigidity: Provides a high degree of stiffness, making it ideal for applications requiring precise shaft positioning and stability.
- Low Friction Operation: The tapered design ensures true rolling contact between rollers and raceways, reducing operational friction and heat generation.
- Durable Construction: Made from high-quality, case-hardened bearing steel for superior wear resistance and extended service life under harsh conditions.
