516449 Designation and Supply Scope
The compact 516449 inquiry code is associated with the HM516449A cone and HM516410 cup in the supported DWB2540 family. The A/410 configuration is distinct from HM516449C/10 and SET422 records, so suffix-controlled dimensions, ratings, and supply details must be checked against the complete designation used for quotation.
Product Features
- The separable cone-and-cup construction supports component-level or matched-assembly sourcing when the required supply scope is stated clearly.
- The 82.55 x 133.35 x 39.688 mm dimensions provide a precise comparison basis for the shaft, housing, and mating components.
- Timken and SKF complete designations provide manufacturer-specific references for cross-checking the 516449 inquiry family.
- Configuration-scoped load ratings and ring widths help prevent technical data from being transferred between incompatible suffix forms.
516449 Ordering Verification
- Match Part Number 516449 with DUHUI DH Code DWB2540 and the intended complete manufacturer designation.
- Confirm whether the order requires the HM516449A cone, HM516410 cup, or matched assembly.
- Check the 82.55 mm bore, 133.35 mm outside diameter, and 39.688 mm total width against the mating components.
- Keep HM516449A/HM516410 separate from HM516449C/10 and other suffix-controlled configurations.

DUHUI Bearing accepts bearing configuration, product marking, and packaging customization for approved B2B order quantities.
