3379 Single Cones (Imperial)

3379 Single Cones (Imperial)

The 3379 single cones are tapered roller bearings with a 1.375″ bore, designed for combined loads and made from durable chrome steel. They handle dynamic radial loads up to 25800 lbf and are built to last in tough conditions.

Their open design and steel cage ensure smooth operation, while the standard radial clearance allows for easy installation. The bearings work well in temperatures from -30°C to 110°C.

These cones are part of the 3300 series and interchangeable with Timken models, making them a reliable choice for replacements. Ideal for heavy-duty applications like truck axles or industrial gearboxes.

Compliant with RoHS and REACH standards, they offer a balance of strength and performance. The ABEC-1 rating ensures consistent quality for general industrial use.
