Product Features
- Single-row tapered roller geometry supports combined radial and axial load handling as a standard bearing-family characteristic.
- The 30.000 mm bore, 72.000 mm outside diameter, and 20.750 mm total width provide a direct dimensional screen before quotation.
- Separate oil and grease speed values, load ratings, enclosure, material, and Class 0 precision help buyers compare the required configuration without mixing catalog definitions.
30306D Ordering Verification
- Match the public Part Number 30306D with the required manufacturer designation and cone-and-cup supply scope.
- Verify the 30.000 mm bore, 72.000 mm outside diameter, and 20.750 mm total width against the mating components.
- Use the listed OE numbers, including AGCO 1109989, SAME 2.2560.003.0, or Toyota 90366-30011, only when the buyer’s source record identifies the same product family.
- Confirm enclosure, clearance, precision, marking, packaging, and final quotation configuration before release.
