Product Overview: The 3875/382A Inch Series Tapered Roller Bearing
The 3875/382A is a high-performance, single-row Inch Series Tapered Roller Bearing designed to withstand heavy-duty applications. This bearing set, comprising the 3875 cone (inner ring assembly) and the 382A cup (outer ring), has a bore diameter of 53.975mm, an outer diameter of 98.425mm, and a total width of 30.163mm. Its core function is to manage a combination of high radial and axial (thrust) loads in one direction. The tapered geometry of the rollers and raceways ensures true rolling motion and low friction, making it an essential component in a wide range of machinery where durability and precision are critical.
As a key part of our Tapered Roller Bearings catalog, the 3875/382A is manufactured from premium-grade bearing steel to ensure exceptional hardness, wear resistance, and a long operational lifespan. The separable design of the cone and cup simplifies installation, removal, and maintenance procedures, offering significant practical advantages in industrial and automotive settings.
Key Features of the 3875/382A Bearing
- Inch-Based Design: Manufactured to standard inch dimensions, ensuring compatibility with a wide range of North American and other specialized equipment.
- Combined Load Capacity: Expertly designed to accommodate both heavy radial loads and significant single-direction axial loads simultaneously.
- Separable Components: The cone (3875) and cup (382A) are separable, allowing for easier mounting, dismounting, and inspection.
- Tapered Raceways: The angle of the raceways is engineered to effectively manage thrust loads and reduce stress concentration.
- Low-Friction Operation: Precision engineering of the rollers and raceways minimizes friction, reducing heat generation and improving efficiency.
- High-Quality Steel Construction: Made from high-carbon chromium bearing steel for superior strength, durability, and resistance to wear and fatigue.
