UCPA Tapped Base Pillow Block Bearing Units
UCPA is a standard duty series configured around tapped base pillow block bearing units. Its catalogue definition uses setscrew locking, with individual bore and dimensional variants retained in one model table.
Series Overview
The catalogue treats this as a distinct series, so the page below follows the same logic: choose the series by housing and locking arrangement, then match the exact unit number and dimensions in the supplied table.
If the machine layout is not fixed yet, compare this family with other mounted-bearing formats before choosing the model row. Housing geometry usually narrows the options faster than bore size alone. Browse related bearing families.
Series-Level Selection
UCPA is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
Mounting Form
The primary configuration is tapped base pillow block bearing units, intended for compact shaft support where threaded mounting from the base is preferred.
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.

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
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.
Packaging and handling equipment
UCPA is relevant when packaging and handling equipment requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
Equipment with limited access below the mounting surface
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.
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
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 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 |
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 UCPA Configuration
A useful RFQ includes the target model or shaft size, mounting dimensions, quantity and any environment requirement. That gives the quotation review enough information to confirm the catalogue row. Ever Power Netherlands Branch can review the quotation basis against the same reference.
