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....
UCFB 3-Bolt Flange Bearing Units
UCFB is a standard duty 3-bolt flange bearing units series for face-mounted support where a three-bolt footprint suits the available plate geometry. The page keeps the complete catalogue drawing and model-by-model dimensional reference together for RFQ selection.
MOQ: 50 pcs. Minimum order value USD 1,500; mixed orders and trial quantities welcome.
UCFB 3-Bolt Flange Bearing Units
UCFB is a standard duty series configured around flange bracket. Its catalogue definition uses setscrew 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
UCFB is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
Mounting Form
The primary configuration is flange bracket, intended for face-mounted support where a three-bolt footprint suits the available plate geometry.
Locking Logic
The catalogue identifies setscrew 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.
| Series | UCFB |
|---|---|
| Catalogue Reference | Part B, page B25 |
| Product Family | 3-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 | flange bracket |
| Material Note | Material varies by unit; confirm selected model |
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
Compact machine frames
For compact machine frames, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
Light conveyors
UCFB is relevant when light conveyors requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
Packaging and process equipment
For packaging and process 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 full table is preserved as a WebP reference so every unit code remains aligned with its dimension columns. Zoom the image when checking closely spaced metric and inch variants.
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 face-mounted support where a three-bolt footprint suits the available plate geometry.
| Step | Information To Confirm |
|---|---|
| 1 | shaft diameter |
| 2 | three-bolt pattern |
| 3 | flange orientation |
| 4 | locking method and available mounting area |
Use the catalogue page as the baseline and add project requirements separately. That keeps source-backed dimensions distinct from requested seals, covers, grease, materials or other options.
RFQ Support
Confirm The Exact UCFB 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.
