A-342STIM-AI TIMKEN CONE

One New Aftermarket Replacement Timken 342S Tapered Roller Bearing Cone

This is a single tapered roller bearing cone (inner ring assembly) replacing Timken part number 342S. The cone pairs with a compatible cup (outer ring, sold separately) to form a complete single-row tapered roller bearing capable of supporting both radial and axial loads. Part of Timken's 300 Series imperial bearing line, the 342S features a stamped steel cage that spaces the rollers evenly to reduce friction, vibration, and noise. Typically mounted in opposing pairs on a shaft, this bearing is suited for high-load, moderate-speed applications across agricultural machinery, construction equipment, conveyor systems, axle assemblies, and other heavy-duty industrial uses.
