TIMKEN 496/493 Tapered Roller Bearing 80.962x136.525x30.162

Overview

The TIMKEN 496/493 is a single row tapered roller bearing designed to support combined radial and axial loads with high rigidity and precise shaft guidance. The tapered roller geometry distributes loads evenly across the raceways, reducing stress concentrations and extending bearing service life. This bearing is suitable for applications exposed to heavy loads, shock loads and continuously changing operating conditions.

Industrial Applications

The bearing is widely used in industrial gearboxes, wheel hubs, axle assemblies, mining machinery, agricultural equipment, construction machinery, heavy-duty conveyors, rolling mills, industrial transmissions and OEM drive systems. It is specified wherever high radial load capacity and accurate axial positioning are required.

Construction

The 496/493 bearing consists of a precision-manufactured cone assembly with tapered rollers and a matching cup. The optimized contact angle enables simultaneous transmission of radial and axial loads while maintaining roller alignment and minimizing friction. Precision-ground raceways ensure stable operation under demanding industrial conditions.

Material

The bearing rings and tapered rollers are manufactured from premium through-hardened bearing steel with high fatigue strength and wear resistance. Advanced heat treatment improves dimensional stability, surface durability and rolling contact performance under heavy-duty operating conditions.
