3479 Single Cones (Imperial)

3479 Single Cones (Imperial)

The 3479 single cones are tapered roller bearings with a 1.4375″ bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 23,500 lbf and thrust loads up to 3,820 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 conditions.

These cones are part of the 3400 series and are interchangeable with Timken models. Ideal for industrial machinery, gearboxes, or heavy-duty applications 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 clearances to suit different needs.
