Series Overview

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.

Series-Level Selection

NA/NA..L3 is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.

Mounting Form

The primary configuration is bearing insert, wide inner ring, intended for insert bearing selection for compatible housings or replacement assemblies.

Locking Logic

The catalogue identifies eccentric locking for this series; confirm the exact row before ordering.

Technical Specifications

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.

Engineering Drawing

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.

Applications

Mounted bearing unit assembly

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.

Replacement of compatible housed inserts

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.

Custom machinery using spherical-OD inserts

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.

Catalogue Dimensional Data

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.

Selection & Integration

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.

StepInformation To Confirm
1shaft diameter
2outer-ring/housing compatibility
3inner-ring width and locking method
4seal 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.

RFQ Support

Confirm The Exact NA/NA..L3 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.
