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....
UC/UC..L3/CUC Insert Ball Bearing Series
UC/UC..L3/CUC is a standard duty bearing inserts series for insert bearing selection for compatible housings or replacement assemblies. 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.
UC/UC..L3/CUC Insert Ball Bearing Series
UC/UC..L3/CUC is a standard duty series configured around bearing insert, wide inner ring. 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
UC/UC..L3/CUC is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
Mounting Form
The primary configuration is bearing insert, wide inner ring, intended for insert bearing selection for compatible housings or replacement assemblies.
Locking Logic
The catalogue identifies setscrew locking for this series; confirm the exact row before ordering.
Technical Specifications
The table below records the series-level facts visible in the supplied catalogue heading. Model-specific dimensions are deliberately kept in the original dimensional table so values are not detached from their unit numbers.
| Series | UC/UC..L3/CUC |
|---|---|
| Catalogue Reference | Part B, page B120 |
| Product Family | Bearing Inserts |
| Duty Classification | Standard duty |
| Locking / Mounting Method | Setscrew locking |
| Inner Ring / Bore Form | Wider inner ring / series-specific bore |
| Housing / Configuration | bearing insert, wide inner ring |
| Material Note | Material varies by unit; confirm selected model |
Engineering Drawing
The drawing is placed directly before the dimensional reference because installation space is usually the quickest way to rule a series in or out. Match the drawing labels to the corresponding columns in the catalogue table before releasing an RFQ.

Applications
Mounted bearing unit assembly
UC/UC..L3/CUC is relevant when mounted bearing unit assembly requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
Replacement of compatible housed inserts
For replacement of compatible housed inserts, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.
Custom machinery using spherical-OD inserts
UC/UC..L3/CUC is relevant when custom machinery using spherical-OD inserts requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.
Catalogue Dimensional Data
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.
Selection & Integration
Begin with the machine mounting envelope, then confirm the shaft and locking arrangement. A similar series code does not guarantee the same center height, bolt pattern, cartridge fit, slot geometry or inner-ring dimensions. In this family, the intended role is insert bearing selection for compatible housings or replacement assemblies.
| Step | Information To Confirm |
|---|---|
| 1 | shaft diameter |
| 2 | outer-ring/housing compatibility |
| 3 | inner-ring width and locking method |
| 4 | seal and relubrication requirement |
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.
RFQ Support
Confirm The Exact UC/UC..L3/CUC Configuration
If the existing code is uncertain, send the shaft size and mounting drawing instead. The series can be checked against the catalogue geometry before the quotation is finalized. Ever Power Netherlands Branch can review the quotation basis against the same reference.
