UEF 4-Bolt Flange Bearing Units
UEF is a standard duty series configured around 4-bolt flange bearing units. Its catalogue definition uses concentric locking, with individual bore and dimensional variants retained in one model table.
Series Overview
The page keeps the full series together because housing geometry and locking method define the product family more clearly than a single bore size. Exact unit numbers remain in the source table for side-by-side checking.
The series can also be compared with other mounted-bearing families when the machine design is still open. Start from the bearing index, then return to the drawing that best matches the mounting interface. Browse related bearing families.
Series-Level Selection
UEF is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
Mounting Form
The primary configuration is 4-bolt flange bearing units, intended for rigid face mounting around a shaft passing through a machine frame.
Locking Logic
The catalogue identifies concentric locking for this series; confirm the exact row before ordering.
Technical Specifications
These specifications describe the family, not a single bore size. Use them to confirm the housing and locking concept, then use the catalogue image for the exact dimensional row.

Engineering Drawing
Check this outline against the machine frame before fixing the bore or unit number. The drawing shows the series geometry; the table below carries the model-by-model dimensions for the same family.
Applications
Conveyor side frames
For conveyor side frames, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
Processing and packaging machinery
UEF is relevant when processing and packaging machinery requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
Material-handling equipment
For material-handling equipment, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
Catalogue Dimensional Data
Rather than shortening the model list, the page keeps the complete source table visible. This lets engineering and purchasing refer to the same row during selection and quotation.
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 rigid face mounting around a shaft passing through a machine frame.
| Step | Information To Confirm |
|---|---|
| 1 | shaft diameter |
| 2 | four-bolt mounting pattern |
| 3 | shaft-to-face geometry |
| 4 | locking method and surrounding clearance |
For an RFQ, dimensions and configuration details are reviewed against the selected catalogue line item. Availability, material exceptions and application-specific options should be confirmed for the exact unit before an order is released.
RFQ Support
Confirm The Exact UEF Configuration
For a faster series check, include the installed unit code when available, plus shaft size, quantity and a photo or drawing of the mounting interface. Ever Power Netherlands Branch can review the quotation basis against the same reference.
