UC Series Set Screw Insert Ball Bearings

This is the right catalog family when the replacement decision centers on a direct shaft lock is preferred and the housing is selected separately. In the supplied catalog, UC / RB 200 Series is shown as insert bearing with dual set screws on extended inner ring and fits matching spherical-seat housings. For UC / RB 200 Series, quotation work moves faster when the source designation, shaft or bore dimension and the controlling mounting measurements are checked before optional seal, grease or housing requests are discussed.

Product Role

The mechanical role is to support the rotating member while preserving a serviceable connection to the frame. With UC / RB 200 Series, matching the bore without checking fits matching spherical-seat housings can produce a part that fits the shaft but not the machine.

Construction & Fit

The cataloged construction combines the bearing function with the surrounding mounting geometry shown on the source page. For UC / RB 200 Series, that chain includes dual set screws on extended inner ring at the shaft and fits matching spherical-seat housings at the machine. Where the UC / RB 200 Series bearing-unit arrangement permits limited static angular accommodation, the shaft line still has to be set correctly before final tightening.

Applications

Common duty examples from this bearing-unit class include conveyors, fan shafts, agricultural machinery, packaging equipment and general transmission supports. A drawing match for UC / RB 200 Series is only part of the decision; contamination, washdown and available service space can change the preferred specification.

Engineering Review

A UC insert is usually selected before the housing when the machine builder already knows the support form but wants a set-screw bearing core. The important replacement check is not only the nominal shaft diameter. Compare inner-ring width, the spherical outside profile, the lock position and the housing seat used by the existing assembly. A UC insert that slides onto the shaft can still be wrong if its width or outside geometry does not match the housing in service.

For maintenance work, photograph the insert while it is still seated and record which side gives access to the two locking screws. If shaft marking is heavy, inspect the fit before installing another bearing. When the old housing is reusable, include its casting designation in the enquiry; that helps keep the insert-to-housing relationship intact instead of treating UC as a universal loose bearing.

A useful workshop check for UC inserts is to compare shaft witness marks with the two set-screw positions. Uneven marking can point to poor seating or a shaft-fit issue. Keep the original insert and housing paired during identification, clean the code area carefully, and record any seal damage before washing the part. Those observations can explain why an apparently correct replacement has a short service life.

If the shaft will be reused, run a fingernail over the set-screw witness marks and measure nearby diameter rather than assuming the untouched area represents the working fit. A local ridge can stop the new UC inner ring from sliding into position and can tempt installers to use impact that should never pass through the rolling elements.

Dimensional Data

The table below gives catalog-backed core dimensions for UC / RB 200 Series where the scan is legible. For UC / RB 200 Series, the specification image in the gallery remains the reference for the complete drawing and every dimension on the selected size row.

Selection Notes

Begin with the dimensions that cannot move in the existing machine. A UC / RB 200 Series replacement needs the actual shaft measurement, the controlling fits matching spherical-seat housings dimensions and confirmation of dual set screws on extended inner ring. Photograph UC / RB 200 Series together with its surrounding structure so the reviewer can see access, adjacent shoulders and possible interference.

Mounting & Integration

Clean the shaft, seat the insert squarely in the housing, rotate the inner ring into its working position, then tighten both set screws to the specified torque for the screw size. The main installation hazard for UC / RB 200 Series is that using the wrong shaft tolerance or tightening the set screws unevenly can reduce concentricity and make later removal difficult. Before startup, inspect UC / RB 200 Series from both sides for trapped seals, contact marks or hardware that could rub once the shaft turns.

Maintenance & Inspection

Check seal condition and running temperature after commissioning; replenish grease only when the housing arrangement provides a relubrication path and the duty actually requires it. For UC / RB 200 Series, keep maintenance notes tied to the installed position so repeated issues can be separated from random one-time events.

Customization & RFQ

For a UC / RB 200 Series replacement enquiry, send the complete code if it is readable, plus shaft size and the mounting dimensions that position the unit. Add a plain-language environment note for UC / RB 200 Series, covering water, abrasive dust, chemicals, cleaning practice and temperature extremes where relevant. Ever Power Netherlands Branch can then review options for UC / RB 200 Series against the supplied application instead of presenting unverified material, seal or grease claims as standard catalog facts.

Cataloged Models

The documented scope on this page includes UC202–UC218 metric and inch-bore variants; RB variants shown alongside selected UC sizes. Keep the complete UC / RB 200 Series suffix or bore variant when matching existing equipment because a shortened code can hide a different locking or dimensional arrangement.
