Product Introduction
The F-809306 is a specialized, OEM-grade tapered roller bearing designed specifically for heavy-duty commercial truck transmission assemblies. Measuring 49.2 x 103.1 x 43.6 mm, this high-precision bearing is engineered to sustain intense helical gear thrust and severe radial loads typical of heavy transportation drivetrains. Built from vacuum-degassed GCr15 high-carbon alloy steel with micro-honed raceways, the F-809306 reduces operational friction, controls temperature buildup, and extends gearbox overhaul intervals. It is an essential SKU for B2B distributors specializing in European truck transmission components and replacement spare parts.
Applications
Commercial heavy truck manual and automated transmissions (ZF series).
Buses, coaches, and heavy off-road transport gearboxes.
Industrial drive units subject to heavy reversing loads.
