3776 Single Cones (Imperial)

The 3776 single cones are tapered roller bearings with a 1.771″ bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 27500 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 with standard radial clearance, but options like C3, C4, or C5 are available for specific needs.

Interchangeable with Timken models, these cones are a practical choice for replacements. They suit applications like gearboxes or heavy machinery where combined loads are common.

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