NAFLU 2-Bolt Flange Bearing Units
NAFLU is a standard duty series configured around compact 2-bolt flange profile. Its catalogue definition uses eccentric locking, with individual bore and dimensional variants retained in one model table.
Series Overview
This series is organized as one catalogue-level product family rather than one product per bore size. That keeps RFQ work focused on the mounting form and locking method first, while the dimensional table remains available for the final unit selection.
This series sits within the wider bearing catalogue. Use the bearing index when comparing another housing format, then return here to verify the selected series drawing and dimensions. Browse related bearing families.
Series-Level Selection
NAFLU is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
Mounting Form
The primary configuration is compact 2-bolt flange profile, intended for compact face mounting with a two-bolt flange footprint.
Locking Logic
The catalogue identifies eccentric locking for this series; confirm the exact row before ordering.
Technical Specifications
This summary deliberately avoids copying isolated dimensions out of context. Family attributes are shown here, and the exact model dimensions stay attached to their original unit numbers in the catalogue reference.

Engineering Drawing
Use the drawing to confirm the mounting envelope before choosing the line item from the catalogue table. Pay particular attention to the shaft centerline, bolt or pilot geometry, overall housing envelope and the dimensions that affect adjacent machine parts.
Applications
Conveyors and small handling systems
For conveyors and small handling systems, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
Packaging machinery
NAFLU is relevant when packaging machinery requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
General industrial frames
For general industrial frames, 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 original model table is shown at high resolution so metric and inch unit numbers remain attached to the correct drawing-letter dimensions. Select the row visually and confirm it again in the RFQ.
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 compact face mounting with a two-bolt flange footprint.
| Step | Information To Confirm |
|---|---|
| 1 | shaft diameter |
| 2 | two-bolt spacing |
| 3 | housing orientation |
| 4 | locking method and shaft alignment |
The supplied catalogue is used here as the technical selection reference. Final quotation review should confirm the exact model, shaft size, mounting interface and any environment-specific requirement.
RFQ Support
Confirm The Exact NAFLU Configuration
Attach the machine or housing drawing with the required quantity and shaft size. This gives the technical review a clear basis for matching the catalogue row without guessing from the series name alone. Ever Power Netherlands Branch can review the quotation basis against the same reference.
