3877A-3820 Tapered Roller Bearing

Key features

• This tapered roller bearing adopts separable cone‑and‑cup construction. The inner assembly (cone with rollers) and outer ring (cup) can be installed separately, which facilitates on‑site assembly, disassembly and axial clearance adjustment according to working requirements.
• Made of bearing steel material with standardized heat‑treatment procedure. Raceway and roller surfaces are precisely processed to maintain proper hardness, supporting continuous operation under medium‑heavy load conditions.
• Tapered rollers provide a broad contact area along the raceways to help distribute applied loads and maintain stable rotational movement.
• Suitable for multiple equipment including industrial transmission parts, agricultural machines, construction machinery, conveyor systems and wheel hub assemblies. Please confirm bore, outer diameter and width before purchase to match your installation space.
• Confirm the bearing model, bore diameter, outside diameter, and overall width before purchase to ensure the dimensions match your application.

This tapered roller bearing is designed for mechanical systems where radial and axial forces may occur at the same time. Its tapered roller and raceway geometry helps transfer operating loads efficiently while supporting smooth and consistent rotation. The separable construction allows the cone assembly and outer cup to be handled independently during installation or maintenance. This design is commonly used in rotating equipment where accurate bearing fit and proper adjustment are important for reliable operation. Suitable for a wide range of mechanical applications, including transmissions, gear assemblies, wheel-related mechanisms, agricultural equipment, industrial machinery, and general repair projects. Applications may vary depending on bearing size, load conditions, rotational speed, lubrication, and installation method. Please verify the model number and all dimensional specifications before ordering, including bore diameter, outside diameter, and bearing width. Proper installation, alignment, lubrication, and operating clearance are recommended for normal bearing performance.
