The UKFC housing with NSK insert bearing is a 4-bolt flange mounted unit that combines a cast iron housing with a spherical roller insert bearing and an adapter sleeve. It is used to support shafts in structures where a robust fixing and a certain self-aligning capability are required. It is a common solution in power transmission and conveying equipment operating under moderate loads and requiring simple, reliable mounting.
The UKFC designation identifies the family of flange housings with insert bearing and adapter sleeve. Examples UKFC217D1;HA2317X and UKFC218D1;HA2318X show the typical structure: UKFC plus the size number, the D1 suffix that distinguishes the insert bearing variant, and the HA code that corresponds to the adapter sleeve for mounting on the shaft. The size number relates to the shaft diameter and the flange dimensions; for each size, MR quotes you the complete assembly with the corresponding sleeve.
In Argentine industry, these housings appear in belt conveyors, bucket elevators, mills, mixers and process equipment where the shaft is supported on a flange bolted to a wall or structure. They are also found in road machinery, aggregate plants and pumping systems. The 4-bolt flange allows firm fixing and distributes the load into the structure, which makes them suitable for installations where the housing cannot rotate or shift.
To select the housing, take into account the shaft diameter, the type of load and the alignment between supports. The HA sleeve allows mounting the bearing on shafts without a shoulder and adjusting the fixing; check that the shaft has the appropriate tolerance and that the flange rests on a flat surface. Lubrication of the insert bearing and sealing against dust and moisture are key to service life. If the equipment operates with slight misalignments, the self-aligning capability of the insert helps compensate for them.
UKFC housings with insert bearing are available under different brands, and dimensional equivalences between manufacturers are common. If you bring the code of another brand or an unidentified part, at MR Accesorios Industriales we indicate the compatible alternative or quote you the exact size you need. Interchangeability is defined by the flange dimensions, the shaft diameter and the type of fixing, not only by the code.
To move forward with your inquiry, send us the housing code, the shaft diameter or a photo of the part via WhatsApp. At MR Accesorios Industriales we quote you the UKFC assembly with its HA sleeve and advise you on mounting and lubrication. With more than 80 years in the industrial market, we handle inquiries for housings and mounted units for equipment throughout Argentina.
