1780 Single Cones (Imperial)

The 1780 single cones are tapered roller bearings with a 1-inch bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 10200 lbf and work well in temperatures from -30°C to 110°C.

Their open design allows easy maintenance, while the steel cage ensures reliable performance. The bearings come in standard radial clearance, with options for C3, C4, or C5 fits.

Interchangeable with Timken models, these cones are a practical choice for replacements. Ideal for applications like automotive axles or industrial gearboxes where combined loads are common.

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