The Timken 30310 92KA1 is a single-row metric tapered roller bearing produced under the Timken IsoClass designation, indicating a complete cup-and-cone assembly conforming to ISO metric standards. Stamped dimensions are 50 mm bore, 110 mm outer diameter, and 29.25 mm combined width. The cone width is 27 mm and the cup width is 23 mm. This bearing is manufactured in France and carries the IsoClass brand designation on both the orange side label and the bearing outer race.

Single-row tapered roller bearings of this type are designed to carry combined radial and axial loads. The separable design allows independent installation of the cone assembly and cup, and they are typically mounted in opposing pairs. Published dynamic load rating for the 30310 is 142,000 N and static load rating is 160,000 N per Timken specification data.

The 30310 size is widely used in gearboxes, industrial transmissions, axle assemblies, conveyor systems, and general power transmission equipment. The 92KA1 suffix identifies this as a Timken IsoClass assembly set. The bearing appears in original Timken packaging with lot code 200801 33 visible on the box label.
