Description
EP-UCFC Round Flange Cartridge Series is an EVER POWER square flange bearing unit. Use the model as the product identity, then verify the machine interface from the specification table and drawing before a replacement or new-build decision.
For EP-UCFC Round Flange Cartridge Series, dimensional fit and duty suitability should be checked separately. The product page separates verified dimensional data from application guidance: dimensions define whether the unit can physically fit, while load, speed, contamination, locking, lubrication and maintenance determine whether the configuration suits the duty.

Technical specifications
Confirm the project-specific dimensional table before ordering this series.
Construction and operating role
The EP-UCFC Round Flange Cartridge Series construction check starts with its own housing, insert and shaft-locking interface. This EP-UCF model combines an insert bearing with a four-bolt square flange housing. The housing is intended for face mounting on a machine plate or frame, supporting a shaft that passes through the mounting face. The insert and housing work as a unit, so bore, insert geometry and flange dimensions must all match the machine.

Selection and replacement checks
When reviewing EP-UCFC Round Flange Cartridge Series for a new build or replacement, measure the shaft, horizontal and vertical bolt pitch, overall flange envelope and any pilot / register feature. Check insert projection and wrench access around the flange. A four-bolt housing with the same bore can still have a different footprint, so use the dimensional drawing rather than appearance alone.
Typical applications
Application screening for EP-UCFC Round Flange Cartridge Series should begin with the shaft position and duty. Common applications include conveyors, agricultural machinery, packaging equipment, fans and general side-plate mounting. The four-bolt flange is useful when the machine frame should carry the support through a face rather than a base.
Installation guidance
During installation of EP-UCFC Round Flange Cartridge Series, seat the flange on a flat mounting face, start all fasteners before final tightening and avoid using the bolts to pull a distorted plate into position. Align paired supports before locking the shaft. Check that the insert and shaft rotate freely after the housing is secured.
Maintenance and inspection
For scheduled inspection of EP-UCFC Round Flange Cartridge Series, watch for unusual temperature, noise, looseness, seal damage, grease leakage, corrosion or fretting on the shaft. If a unit fails prematurely, preserve the old part and document the failure condition before changing model or housing style. Correct alignment, shaft condition and contamination control are part of bearing life.
Replacement identification and cross-reference
When EP-UCFC Round Flange Cartridge Series is compared with an existing third-party reference, include the complete part number used on the machine. References such as SKF, FAG/Schaeffler, NSK, NTN, Timken, INA or JTEKT/Koyo are used to identify the likely product family. Final selection is confirmed from bore, housing geometry, locking method and machine duty rather than from a brand-name equivalence statement.
On the EP-UCFC Round Flange Cartridge Series page, third-party names are used only to identify an existing bearing, compare references or support product selection. All trademarks and brand names mentioned remain the property of their respective owners. Their appearance here does not imply affiliation, sponsorship, authorization or endorsement. Final replacement selection should be confirmed from dimensions, locking method and the actual machine interface.
Frequently asked questions
What is the most important replacement dimension?
For EP-UCFC Round Flange Cartridge Series, in addition to bore, confirm the four-bolt pitch and flange envelope. These decide whether the housing will fit the machine plate.
Can a square flange be replaced by an oval flange?
For EP-UCFC Round Flange Cartridge Series, only if the machine structure is redesigned or already supports the alternate bolt pattern. The two housing styles are not automatic substitutes.
Should the flange bolts be tightened before shaft alignment?
For EP-UCFC Round Flange Cartridge Series, bring the housing into position and align paired supports before final tightening so the shaft is not forced into bind.
What should I send for a cross-reference enquiry?
Send the complete existing model, shaft size, bolt pitch, photos/drawing and operating conditions.
Prepare your RFQ
For an EP-UCFC Round Flange Cartridge Series quotation, send the EP model or existing reference, shaft size, housing / mounting dimensions, quantity, application, operating environment and a drawing or photo when replacement geometry is uncertain.
