NAFC Flange Cartridge Bearing Units
NAFC is a standard duty series configured around flange cartridge bearing units. Its catalogue definition uses eccentric locking, with individual bore and dimensional variants retained in one model table.

Series Overview
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.
Series-Level Selection
NAFC is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
Mounting Form
The primary configuration is flange cartridge bearing units, intended for piloted or cartridge-style face support around a shaft opening.
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
Machine end plates
For machine end plates, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
Conveyor and processing frames
NAFC is relevant when conveyor and processing frames requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
Rotating equipment housings
For rotating equipment housings, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
Catalogue Dimensional Data
Use this catalogue table for the final unit-number check. It preserves the source row order, dimensional columns and metric/inch alternatives on one reference image.
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 piloted or cartridge-style face support around a shaft opening.
| Step | Information To Confirm |
|---|---|
| 1 | shaft diameter |
| 2 | cartridge pilot/fit geometry |
| 3 | bolt pattern |
| 4 | locking method and face clearance |
Before quotation, confirm the source row that matches the required shaft and housing dimensions. Any option not stated for that row should be treated as an RFQ item rather than assumed as standard.
RFQ Support
Confirm The Exact NAFC 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.
