Stainless steel gearboxes are widely used in industrial transmission fields due to their high strength and corrosion resistance. However, in actual use, stainless steel gearboxes may still malfunction due to improper design, installation, lubrication or maintenance....
UCF 4-Bolt Flange Bearing Units
UCF is a standard duty 4-bolt flange bearing units series for rigid face mounting around a shaft passing through a machine frame. The page keeps the complete catalogue drawing and model-by-model dimensional reference together for RFQ selection.
MOQ flexible. Minimum order value USD 1,500; mixed orders and trial quantities welcome.
UCF 4-Bolt Flange Bearing Units
UCF is a standard duty series configured around 4-bolt flange bearing units. Its catalogue definition uses setscrew locking, with individual bore and dimensional variants retained in one model table.

Series Overview
For purchasing and replacement work, the useful decision is the series itself, not a separate web page for every shaft size. The model table therefore stays together so adjacent metric and inch variants can be compared in one place.
Treat the housing format and locking method as the first filter. The broader bearing range is useful when the same shaft size must be checked against another flange, pillow, take-up or insert arrangement. Browse related bearing families.
Series-Level Selection
UCF 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 setscrew 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.
| Series | UCF |
|---|---|
| Catalogue Reference | Part B, page B17 |
| Product Family | 4-Bolt Flange Bearing Units |
| Duty Classification | Standard duty |
| Locking / Mounting Method | Setscrew locking |
| Inner Ring / Bore Form | Wider inner ring / series-specific bore |
| Housing / Configuration | 4-Bolt Flange Bearing Units |
| Material Note | Material varies by unit; confirm selected model |
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
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
UCF 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
The dimensional data is retained as one complete source table. This is especially useful when adjacent sizes share a housing but differ in shaft, inner-ring or mounting dimensions.
Selection & Integration
For replacement work, measure the installed interface before selecting by code. Shaft size is important, but housing geometry and the locking arrangement usually decide whether a unit will fit without rework. 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 |
The model code should be verified together with its dimensional row. This is particularly important where metric and inch variants share similar housings but differ at the shaft interface.
RFQ Support
Confirm The Exact UCF 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.
Evidence note: supplied catalogue page B17 is the source for this series geometry and dimensional table. Final project suitability and commercial availability are confirmed during RFQ review.
