209/211/491 Disk Harrow is a application-specific agricultural/farm implement bearings series for bearing support for farm implement and disk-harrow style applications. The page keeps the complete catalogue drawing and model-by-model dimensional reference together for RFQ selection.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.
209/211/491 Disk Harrow is a application-specific series configured around disk harrow bearing unit. Its catalogue definition uses see catalogue drawing/table, with individual bore and dimensional variants retained in one model table.
The catalogue treats this as a distinct series, so the page below follows the same logic: choose the series by housing and locking arrangement, then match the exact unit number and dimensions in the supplied table.
If the machine layout is not fixed yet, compare this family with other mounted-bearing formats before choosing the model row. Housing geometry usually narrows the options faster than bore size alone. Browse related bearing families.
209/211/491 Disk Harrow is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
The primary configuration is disk harrow bearing unit, intended for bearing support for farm implement and disk-harrow style applications.
The catalogue identifies see catalogue drawing/table for this series; confirm the exact row before ordering.
Start with these family-level identifiers before reading across the dimensional table. They are the details most likely to distinguish a neighboring series with a similar overall appearance.

Read the drawing from the mounting interface inward. Check bolt or pilot geometry and shaft centerline first, then compare the remaining lettered dimensions with the same unit row in the catalogue table.
For disk harrows and tillage equipment, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
209/211/491 Disk Harrow is relevant when farm implement hubs and rollers requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
For outdoor agricultural machinery, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
Below is the full dimensional reference for this series rather than a shortened web transcription. Keeping the table intact reduces the risk of separating a dimension from the wrong bore or unit suffix.
A replacement should be checked against measurable interfaces, not appearance alone. Record the shaft size, mounting pattern, centerline or pilot dimensions and the method used to secure the bearing to the shaft. In this family, the intended role is bearing support for farm implement and disk-harrow style applications.
| Step | Information To Confirm |
|---|---|
| 1 | round or square shaft/bore requirement |
| 2 | bearing profile/type |
| 3 | relubricatable or non-relubricatable preference |
| 4 | contamination and sealing conditions |
A practical selection review starts with geometry and locking method, then verifies the exact model row. Special coatings, covers, grease, seals or material options should only be treated as included when they are stated for the chosen configuration.
Quotation review is more reliable when the request includes the model row, shaft size and installation drawing. Add any corrosion, cleaning or maintenance requirement that could change the configuration. Ever Power Netherlands Branch can review the quotation basis against the same reference.
