Rated for a 3.4843 in. outer diameter and 1-5/16 in. width, the Timken 4320 is a Series 435 single cup outer race used in the assembly of single row tapered roller bearings. The cup pairs with a separately sold cone (inner race) assembly to form a complete bearing capable of carrying both radial and thrust loads. Manufacturer published specifications include a 0.130 in. maximum housing fillet radius and standard tolerance class. Construction is Timken high alloy bearing steel with an open configuration that allows for in-place lubrication and endplay or preload adjustment during equipment assembly. The 4320 part number is the market recognized OEM identifier for this Series 435 cup and is referenced consistently across industrial distributor catalogs including Applied, Eastern Industrial Automation, and Monarch Bearing. The cup is supplied in original Timken Tapered Roller Bearings packaging marked 4320 with lot code 200107 22. Single row tapered roller bearings of this size are commonly applied in vehicle axles, transmissions, wheel hubs, industrial gearboxes, conveyor drives, and other mechanical power transmission applications calling for combined load capacity. Operating temperature range per published Timken data is 65 to 250 degrees F. The 4320 2 variant referenced by some distributors corresponds to the same Series 435 cup with a different packaging or precision designation. This item is the cup only and does not include a matching cone.
