The Y-bearing housing with insert bearing is a mounted unit that combines a cast iron housing with an insert ball bearing, ready to fix to the structure. The NSK UKFCX series corresponds to 4-bolt flange housings, with a spherical outer insert and taper sleeve fixing system. It is used to transmit motion in equipment requiring alignment and simple mounting, such as belt conveyors, agitators or industrial fans. MR Accesorios Industriales sells this line for plants in Buenos Aires, Argentina and throughout the country.
The UKFCX designation identifies the series: UK indicates the insert bearing with taper sleeve, FC the 4-bolt flange and X the size variant. The number that follows — for example in UKFCX11D1 — indicates the insert size. The D1 suffix corresponds to a version with a higher-sealing lip seal. In the case of HE2311XY, HE is the adapter sleeve and 2311 its size; XY refers to the lock nut and lock washer. Knowing these parts allows you to order the complete assembly or the exact spare part.
These housings are used in the food, chemical, cement and materials handling industries. In Argentina they are commonly seen in belt conveyors, mixers, blowers, centrifugal pumps and packaging equipment. The 4-bolt flange allows mounting on sheet metal or profile structures, with the shaft perpendicular to the surface. The spherical insert accommodates slight misalignments, which simplifies installation and reduces wear in applications with vibration or moderate loads.
To select the housing, take into account the shaft diameter, radial and axial load, and environmental conditions. The D1 sealing protects against dust and humidity, suitable for demanding environments. The HE taper sleeve facilitates mounting and dismounting without a press. Lubricate the insert with lithium grease according to the duty cycle. Check the alignment of the flange and the tightening of the bolts before start-up. Correct levelling prevents stress on the bearing and extends its service life.
Y-bearing housings with insert bearing are interchangeable between brands under equivalent standards. If the equipment carries a code from another company, we can identify the equivalence by dimensions and fixing type. The NSK UKFCX series corresponds to similar lines from other manufacturers, provided the shaft diameter, hole spacing and insert type match. MR Accesorios Industriales advises you to choose the compatible option without modifying the mounting.
