UCTB is a standard duty tapped base pillow block bearing units series for compact shaft support where threaded mounting from the base is preferred. 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.
UCTB is a standard duty series configured around tapped-base housing. Its catalogue definition uses setscrew locking, with individual bore and dimensional variants retained in one model table.
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.
UCTB is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
The primary configuration is tapped-base housing, intended for compact shaft support where threaded mounting from the base is preferred.
The catalogue identifies setscrew locking for this series; confirm the exact row before ordering.
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.

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.
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.
UCTB is relevant when packaging and handling equipment requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
For equipment with limited access below the mounting surface, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
Below is the full dimensional reference for this series rather than a shortened web transcription. Keeping the table intact reduces the risk of separating a dimension from the wrong bore or unit suffix.
For new equipment, select the housing format before finalizing the shaft detail. For replacement work, reverse the process and measure the existing shaft and frame so the catalogue drawing can be matched directly. In this family, the intended role is compact shaft support where threaded mounting from the base is preferred.
| Step | Information To Confirm |
|---|---|
| 1 | shaft diameter |
| 2 | threaded base pattern |
| 3 | center height |
| 4 | locking method and service access |
A practical selection review starts with geometry and locking method, then verifies the exact model row. Special coatings, covers, grease, seals or material options should only be treated as included when they are stated for the chosen 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.
