UC300 Insert Ball Bearing Series

UC300 is a heavy duty series configured around heavy-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

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

UC300 is treated as one catalogue series, with individual unit numbers retained inside the dimensional table.

Mounting Form

The primary configuration is heavy-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

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.

Applications

Mounted bearing unit assembly

For mounted bearing unit assembly, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.

Replacement of compatible housed inserts

UC300 is relevant when replacement of compatible housed inserts requires this housing format; verify shaft geometry, mounting interface, operating conditions and environment before final selection.

Custom machinery using spherical-OD inserts

For custom machinery using spherical-OD inserts, this series provides the catalogue mounting form shown above. Confirm load, speed, shaft dimensions and service environment for the chosen model.

Catalogue Dimensional Data

Use this catalogue table for the final unit-number check. It preserves the source row order, dimensional columns and metric/inch alternatives on one reference image.

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 insert bearing selection for compatible housings or replacement assemblies.

4seal and relubrication requirement

Before quotation, confirm the source row that matches the required shaft and housing dimensions. Any option not stated for that row should be treated as an RFQ item rather than assumed as standard.

Confirm The Exact UC300 Configuration

Share the catalogue unit you are considering plus quantity and the machine drawing. If the unit number is unknown, measured shaft and mounting dimensions can be used to narrow the series first. Ever Power Netherlands Branch can review the quotation basis against the same reference.
