843 Single Cones (Imperial)

843 Single Cones (Imperial)

The 843 single cones are tapered roller bearings with a 3-inch bore, designed for combined loads. Made from durable chrome steel, they handle dynamic radial loads up to 109,000 lbf and operate smoothly in temperatures from -30°C to 110°C.

Their open design allows easy maintenance, 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 bearings, these cones are a practical choice for replacements. Ideal for heavy-duty applications like industrial machinery or vehicle axles 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 most industrial uses.
