Tapered roller bearings with imperial (inch) dimensions are widely used on automotive hubs, agricultural transmissions, and industrial equipment originally built to imperial standards. Unlike metric bearings, inch tapered roller bearings follow ABMA sizing conventions and are often supplied under Timken-style part numbers.
Our inch tapered roller bearings feature a separable inner and outer ring design, allowing for easier installation and maintenance. This construction also provides high radial and axial load capacity, making them well suited for wheel hubs, differentials, and heavy-duty transmission assemblies.
Many imperial bearing sizes used on legacy or imported equipment are no longer available through standard distributor channels. If you cannot find your exact inch tapered roller bearing size, send us the dimensions, a sample, or the original part number — our engineering team can confirm the correct match or manufacture a custom replacement.
