UCFC200 Series Flange Cartridge Bearing Units
UCFC200 is the straightforward choice in this group when a machine already has a round, four-bolt flange position and the shaft can be retained with a conventional setscrew insert. The housing sits close to the machine face, so it works well on frames where a foot-mounted block would add unwanted height.
The practical value of the series is familiarity. Bore, pilot, bolt-circle and overall housing dimensions can be checked as one package, which makes UCFC useful for both new equipment and replacement work. It is not the only cartridge option, however; the locking method and duty level should be confirmed before a like-for-like substitution is approved.
For a wider housing comparison, browse the bearings range before finalising the mounting style.
Why UCFC200 is the baseline cartridge choice
Round four-bolt geometry
A round flange and four mounting positions make the housing easy to locate around an existing pilot or machined face.
Setscrew shaft retention
The insert is retained on the shaft by setscrews, keeping the selection process simple when this locking method is already used on the machine.
Broad standard-duty range
Published sizes run from 12 mm through 90 mm, giving one housing concept across a wide span of common shaft diameters.
Replacement-friendly data
The catalogue publishes the pilot, bolt circle, overall housing and insert dimensions needed to compare an existing unit.

Dimensions that matter on a face-mounted replacement
Use the product drawing as the final dimensional authority. The points below are practical filters that help narrow the correct model before a full drawing comparison.
Measure the pilot or locating diameter, bolt-circle position and available flange envelope before looking only at shaft bore.
A matching bore is necessary, but the setscrew arrangement must also suit the existing shaft and service practice.
Compare housing thickness and insert projection with guards, pulleys, couplings or adjacent frame members.
A large mismatch in published unit weight can be a warning that the compared housing belongs to another duty series.
Where this series earns its keep
These are application patterns where the housing concept is commonly considered. Final suitability still depends on load, speed, alignment, environment and the machine designer’s requirements.
Conveyor side frames
Useful where a shaft passes through a side plate and the bearing needs to sit close to that face.
Packaging machinery
Round flange geometry can simplify compact bearing stations around rollers, shafts and driven modules.
Fans and light process equipment
A face-mounted bearing support is convenient where pedestal height is limited or the housing is mounted to an end plate.
Agricultural equipment
The broad bore range supports replacement work on fabricated frames, guards and drive assemblies that use four-bolt cartridge units.
Installation checks before the machine goes back into service
Paint build-up, burrs and trapped debris can prevent the flange from seating squarely.
Bring the mounting bolts down progressively so the pilot and flange are not pulled sideways during tightening.
Remove corrosion and raised marks before the setscrews are tightened.
After the first operating period, inspect mounting bolts, shaft retention and bearing temperature as part of normal commissioning.
Choosing UCFC200 rather than another FC family
Choose UCFC200 when standard-duty construction, four-bolt round flange geometry and setscrew locking all match the job. If the same housing concept is needed with a different shaft-locking method, NAFC200, UEFC200 or UKFC200+H may be a closer starting point. If the application needs a heavier cartridge body, compare the UCFCX00 family instead.
Send the machine details for a model check
For UCFC200, send the existing model marking, shaft diameter, mounting dimensions and a photo of the bearing position. GBC can review the information against the published series before quotation. Email: sales@australia-drive.com.
