/339-Single-Cones-(Imperial)-Dimensions.webp)
The 339 single cones are tapered roller bearings with a 1.378″ bore, designed for combined loads and made from durable chrome steel. They handle dynamic radial loads up to 21200 lbf and operate smoothly in temperatures from -30°C to 110°C.
Their single-row construction and open design make them easy to maintain, while the steel cage ensures reliable performance. The bearings come in standard radial clearance, with options for C3, C4, or C5 if needed.
These cones are interchangeable with Timken models, offering flexibility for replacements. Ideal for heavy-duty applications like truck axles or industrial gearboxes where combined loads are common.
Compliant with RoHS and REACH standards, they provide a safe and robust solution for demanding environments. Their ABEC-1 rating ensures consistent performance for general industrial use.
