/346-Single-Cones-(Imperial)-Dimensions.webp)
The 346 single cones are tapered roller bearings with a 1.25″ bore, designed for combined loads. Made from durable chrome steel, they handle radial loads up to 21200 lbf and thrust loads up to 2570 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.
These cones are interchangeable with Timken models, making them a practical choice for replacements. Ideal for heavy-duty applications like axles or industrial gearboxes where combined loads are common.
Compliant with RoHS and REACH standards, they offer a balance of strength and durability. The standard radial clearance can be adjusted to C3, C4, or C5 for specific needs.
