Timken 861 Series Tapered Roller Bearing Cone | High-Capacity Industrial Standard
The Timken 861 Tapered Roller Bearing (TRB) cone is engineered for exceptional performance in high-stress, high-precision industrial and automotive applications. Manufactured from proprietary, case-hardened alloy steel, the 861 cone is designed to handle simultaneous radial and heavy thrust loads, making it ideal for gear drives, truck differentials, and heavy machinery axles. The precision-machined rolling elements and raceway geometry minimize friction and heat generation, significantly extending bearing life and ensuring dimensional stability across severe operating temperature ranges. This component adheres to stringent international dimensional standards, guaranteeing seamless interchangeability and reliable performance.
Selecting the 861 ensures maximized uptime and a reduced Total Cost of Ownership (TCO) compared to standard commercial alternatives. Timken's proprietary finishing process enhances surface contact area, reducing stress concentration and wear under cyclic loading. This robustness makes the 861 the preferred solution for operations where reliability is non-negotiable, such as fleet maintenance, mining equipment, and critical pump systems. Pair the 861 cone with its corresponding cup (typically 854 or similar) for a fully optimized bearing assembly capable of delivering consistent, high-torque power transmission and alignment stability.
