The UKFX housing with NSK insert bearing is a four-bolt flange unit that combines an insert bearing with a cast iron housing. It is used to mount rotating shafts on flat structures, where the flange is fastened with four bolts and the insert is secured to the shaft. It is a compact and simple-to-mount solution for equipment requiring rigid support and straightforward alignment.
The UKFX designation identifies the series of four-bolt flange housings with insert bearing. The number that follows indicates the shaft diameter for which the insert is intended: UKFX09 corresponds to a 45 mm shaft, UKFX10 to 50 mm, UKFX11 to 55 mm, UKFX13 to 65 mm, UKFX15 to 75 mm and UKFX16 to 80 mm. The D1 suffix indicates construction variants within the series, and the HA code appearing in the examples (HA2309, HA2310, etc.) identifies the associated mounting sleeve. Knowing these components allows you to select the complete unit or its parts separately.
These housings are used in a wide variety of industrial applications in Argentina: belt conveyors, bucket elevators, mixers, mills, pumps, fans and process equipment in food, chemical and aggregate processing plants. Their four-bolt flange facilitates mounting on flat surfaces and allows precise shaft alignment. Being self-aligning units, they tolerate small misalignments and simplify maintenance in equipment operating in dusty or humid environments.
To correctly select a UKFX housing, take into account the shaft diameter, the expected radial and axial loads, and the environmental conditions. The insert usually comes with labyrinth or contact sealing, suitable for retaining grease and excluding contaminants. Mounting is done with the adapter sleeve, which secures the insert to the shaft by means of a lock nut. It is important to verify flange alignment and lubricate according to the manufacturer's recommendations to extend service life.
As for equivalents, NSK UKFX housings can be interchanged with units from other brands that follow the same four-bolt flange standard and equivalent shaft diameters. When quoting, it is useful to compare the flange dimensions, the distance between holes and the shaft diameter. If the customer brings a part number from another brand or an unidentified part, at MR Accesorios Industriales we can indicate the compatible alternative. Interchangeability depends on the critical mounting dimensions being respected.
