UCFL300 2-Bolt Flange Bearing Units
UCFL300 is a heavy duty series configured around 2-bolt flange bearing units. Its catalogue definition uses setscrew 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
UCFL300 is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
Mounting Form
The primary configuration is 2-bolt flange bearing units, intended for compact face mounting with a two-bolt flange footprint.
Locking Logic
The catalogue identifies setscrew locking for this series; confirm the exact row before ordering.

Engineering Drawing
When replacing an installed unit, use the outline drawing as a dimensional fingerprint. Match the fixed machine dimensions before relying on a partially legible model code or a visually similar housing.
Applications
Conveyors and small handling systems
UCFL300 is relevant when conveyors and small handling systems requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
Packaging machinery
For packaging machinery, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
General industrial frames
UCFL300 is relevant when general industrial frames requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
Catalogue Dimensional Data
All catalogue rows for this family remain together below. Check the chosen bore or accessory code against the drawing letters, then include that exact unit designation in the RFQ.
Selection & Integration
Selection should move from fixed machine dimensions to the bearing code: first the mounting interface, then shaft size, then locking method and environment. This avoids choosing a familiar-looking unit that does not match the frame. 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 |
Series nomenclature helps narrow the choice, but the final check should be made against the model row and installation data. This avoids treating a nearby bore size or housing variant as interchangeable without verification.
RFQ Support
Confirm The Exact UCFL300 Configuration
Send the current bearing designation and quantity if available. For a new design, provide shaft size and mounting geometry so the family can be checked before a specific unit number is proposed. Ever Power Netherlands Branch can review the quotation basis against the same reference.
