Product Overview: The 387A/382S Inch Tapered Roller Bearing Set
The 387A/382S is a single-row inch series Tapered Roller Bearing set, a robust and versatile component designed for heavy-duty applications. This set consists of the 387A cone (the inner ring with rollers and cage) and the 382S cup (the outer ring). With a bore diameter of 53.975mm, an outer diameter of 93.264mm, and a total width of 24.608mm, this bearing is engineered to handle a combination of significant radial and axial loads in one direction. Its design ensures true rolling motion and low friction, making it an essential part for demanding machinery.
As a key item in our Inch Tapered Roller Bearings collection, the 387A/382S is manufactured to precise industry standards using high-quality bearing steel for maximum durability and performance. The separable design of the cone and cup simplifies mounting, dismounting, and maintenance procedures, offering flexibility during assembly. This bearing is a reliable choice for a wide array of industrial and automotive applications where load capacity and longevity are critical.
Key Features of the 387A/382S Bearing
- Combined Load Capacity: Expertly designed to manage both high radial and axial (thrust) loads simultaneously in one direction.
- Separable Components: The cone (387A) and cup (382S) are separable, allowing for easier installation, inspection, and maintenance.
- Inch Series Design: Manufactured to standard inch dimensions, ensuring interchangeability with other industry-standard parts.
