UCX/UCX..L3 Insert Ball Bearing Series
UCX/UCX..L3 is a medium duty series configured around medium-duty bearing insert, wide inner ring. 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
UCX/UCX..L3 is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.
Mounting Form
The primary configuration is medium-duty 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
Series attributes are separated from model dimensions here. This makes the page easier to scan while keeping the original line-by-line dimensional reference intact below.
| Series | UCX/UCX..L3 |
|---|---|
| Catalogue Reference | Part B, page B122 |
| Product Family | Bearing Inserts |
| Duty Classification | Medium duty |
| Locking / Mounting Method | Setscrew locking |
| Inner Ring / Bore Form | Wider inner ring / series-specific bore |
| Housing / Configuration | medium-duty bearing insert, wide inner ring |
| Material Note | Material varies by unit; confirm selected model |
Engineering Drawing
For replacement work, compare the drawing with the installed housing rather than relying on a familiar series code alone. Mounting dimensions and locking details are the better confirmation points.
Applications
Mounted bearing unit assembly
UCX/UCX..L3 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
UCX/UCX..L3 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
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
Selection should move from fixed machine dimensions to the bearing code: first the mounting interface, then shaft size, then locking method and environment. This avoids choosing a familiar-looking unit that does not match the frame. 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 |
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 UCX/UCX..L3 Configuration
Include the exact bore or unit suffix whenever possible. A photo of the installed housing and a few fixed mounting dimensions are useful when a legacy code is incomplete. Ever Power Netherlands Branch can review the quotation basis against the same reference.
