NA/NA..L3 is a standard duty bearing inserts series for insert bearing selection for compatible housings or replacement assemblies. 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.
NA/NA..L3 is a standard duty series configured around bearing insert, wide inner ring. Its catalogue definition uses eccentric locking, with individual bore and dimensional variants retained in one model table.
This product page groups the complete catalogue series under one title. Engineers can compare the available unit numbers inside the dimensional reference instead of moving between many nearly identical SKU pages.
Series selection works best from the machine interface outward: mounting face, shaft, locking method and finally the exact catalogue line. Related bearing families can be compared from the main bearing index. Browse related bearing families.
NA/NA..L3 is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
The primary configuration is bearing insert, wide inner ring, intended for insert bearing selection for compatible housings or replacement assemblies.
The catalogue identifies eccentric locking 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.
| Series | NA/NA..L3 |
|---|---|
| Catalogue Reference | Part B, page B123 |
| Product Family | Bearing Inserts |
| Duty Classification | Standard duty |
| Locking / Mounting Method | Eccentric locking |
| Inner Ring / Bore Form | Wider inner ring / series-specific bore |
| Housing / Configuration | bearing insert, wide inner ring |
| Material Note | Material varies by unit; confirm selected model |
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 mounted bearing unit assembly, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
NA/NA..L3 is relevant when replacement of compatible housed inserts requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
For custom machinery using spherical-OD inserts, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
The full table is preserved as a WebP reference so every unit code remains aligned with its dimension columns. Zoom the image when checking closely spaced metric and inch variants.
Check the dimensions that cannot change on the machine first. Once bolt pattern, centerline or pilot geometry and shaft size are known, the locking and environment details can be used to finish the selection. In this family, the intended role is insert bearing selection for compatible housings or replacement assemblies.
| Step | Information To Confirm |
|---|---|
| 1 | shaft diameter |
| 2 | outer-ring/housing compatibility |
| 3 | inner-ring width and locking method |
| 4 | seal and relubrication requirement |
Use the catalogue page as the baseline and add project requirements separately. That keeps source-backed dimensions distinct from requested seals, covers, grease, materials or other options.
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.
