UCF Square Flange Bearing Units

EP-UCF square flange bearing units use a four-bolt mounting pattern around the shaft centreline. The layout is useful when a shaft passes through or terminates at a machine frame and a wider mounting footprint is available.EP-UCF dimensional rangeConfirm the shaft size together with the flange outside dimensions, bolt-hole pitch, projection and mounting-hole diameter. These values help prevent a replacement unit from fitting the shaft but missing the existing bolt pattern.ModelShaft d (mm)LJA2A1AENSBoltInsertHousingMass (kg)EP-UCF204208664151125.533.31212.7M10EP-UC204EP-F2040.61EP-UCF20525957016132735.81214.3M10EP-UC205EP-F2050.8EP-UCF206301088318133140.21215.9M10EP-UC206EP-F2061.07EP-UCF207351179219153444.41417.5M12EP-UC207EP-F2071.4EP-UCF2084013010221153651.21619M12EP-UC208EP-F2081.8EP-UCF2094513710522163852.21619M14EP-UC209EP-F2092.2EP-UCF2105014311122164054.61619M16EP-UC210EP-F2102.4Where the four-bolt format helpsSquare flange units provide a broad mounting footprint for conveyors, agricultural equipment, material handling frames and general industrial machinery.

Confirm the bore, flange width, bolt-hole pitch, pilot / register dimensions where applicable and available installation space. Compare the drawing before assuming another square flange uses the same pattern.Typical applicationsSquare flanges appear in conveyors, agricultural machines, packaging equipment, fans and general frames. They are useful where a base-mounted pillow block would not fit or where the support load should be carried through a face plate.Frequently asked questionsWhen should I choose EP-UCF instead of EP-UCP?Choose from mounting orientation: EP-UCF is a four-bolt face-mounting family, while EP-UCP is a two-bolt base-mounted pillow block.Are all four-bolt flange housings the same?No. Bore, bolt pitch, flange size, pilot geometry and insert width can vary. Verify the dimensional drawing.Can I reuse the existing shaft?Potentially, if shaft diameter, condition and the required locking fit are suitable. Inspect for wear or set-screw damage.What RFQ dimensions are most useful?Shaft diameter, horizontal and vertical bolt pitch, housing / flange dimensions and a photo of the mounting plate.Related bearing-unit familiesFor a two-bolt oval footprint see EP-UCFL; for a base support see EP-UCP; for a compact bracket position an EP-UCFB-style housing may be relevant where the machine geometry matches.Request a category quoteSend shaft diameter, mounting dimensions, locking method, application, quantity and any drawing or existing part number.
