745 Single Cones (Imperial)

The 745 single cones are tapered roller bearings with a 2.36″ bore, designed for combined loads. Made from durable chrome steel, they handle radial loads up to 71,400 lbf and thrust loads up to 10,300 lbf.

Their open design allows 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.

With standard radial clearance and ABEC-1 rating, they offer a balance of precision and durability. Compliant with RoHS and REACH standards for safe use.
