2788 Single Cones (Imperial)

2788 Single Cones (Imperial)

The 2788 single cones are imperial-sized tapered roller bearings with a 1.5″ bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 19500 lbf and static loads up to 23000 lbf.

Their single-row construction and open design allow for easy maintenance, while the steel cage ensures reliable performance. The bearings operate smoothly in temperatures from -30°C to 110°C.

These cones are interchangeable with Timken models, making them a practical choice for replacements. Ideal for heavy-duty applications like truck axles or industrial gearboxes where combined loads are common.

Compliant with RoHS and REACH standards, they offer a balance of strength and durability. Available in standard radial clearance, with options for C3, C4, or C5 if needed.
