34300 Single Cones (Imperial)

The 34300 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 23,000 lbf and operate smoothly in temperatures from -30°C to 110°C.

Their open design and steel cage ensure easy maintenance and long service life. The bearings come in standard radial clearance, with options for C3, C4, or C5 fits to suit different needs.

These cones are part of the 34000 series and are interchangeable with Timken models. Ideal for heavy-duty applications like industrial gearboxes or vehicle axles where reliability is key.

Compliant with RoHS and REACH standards, they offer a robust solution for demanding environments. The ABEC-1 rating ensures consistent performance for general industrial use.
