744AH Single Cones (Imperial)

744AH Single Cones (Imperial)

The 744AH single cones are tapered roller bearings with a 2.875″ bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 81300 lbf and static loads up to 88600 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, making them suitable for various industrial conditions.

These cones are part of the 745 series and are interchangeable with Timken bearings, offering flexibility for replacements. Ideal for heavy-duty applications like gearboxes or wheel hubs where combined loads are common.

Compliant with RoHS and REACH standards, they provide a robust and safe solution for demanding environments. The standard radial clearance can also be adjusted to C3, C4, or C5 as needed.
