3879 Single Cones (Imperial)

3879 Single Cones (Imperial)

The 3879 single cones are tapered roller bearings with a 1.5748-inch bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 27900 lbf and static loads up to 33200 lbf.

Their open design allows easy maintenance, while the steel cage ensures reliable performance. The bearings operate smoothly in temperatures ranging from -30°C to 110°C.

These cones are part of the 3800 series and are interchangeable with Timken models. Ideal for heavy-duty applications like truck axles or industrial gearboxes where combined loads are common.

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.
