3578A Single Cones (Imperial)

3578A Single Cones (Imperial)

The 3578A single cones are imperial-sized tapered roller bearings with a 1.75″ bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 25500 lbf and static loads up to 30100 lbf.

Their open design and steel cage ensure reliable performance in temperatures from -30°C to 110°C. The effective center location of -0.4″ helps with precise alignment in various setups.

These cones are interchangeable with Timken bearings, making them a practical choice 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 offer a balance of strength and durability. Available in standard radial clearance, with options for C3, C4, or C5 if needed.
