The UCFX housing with NTN insert bearing is a 4-bolt flange mounted bearing unit designed to secure rotating shafts to flat structures. Its gray cast iron body incorporates an insert bearing with an extended inner ring and set screws, which simplifies mounting and accommodates slight misalignment. It is used in conveyors, agitators, pumps and process equipment where robust, easy-to-maintain support is required. MR Accesorios Industriales sells this line with technical advice to select the correct size.
The UCFX designation identifies the series of 4-bolt flange housings with insert bearing. The numbers that follow indicate the shaft diameter and the type of locking: for example, UCFX05-013D1 corresponds to a 5/8" shaft with an insert of specific characteristics, while UCFX05D1 indicates the standard variant for the same diameter. The D1 suffix distinguishes the version with a contact seal and long-life lubrication. Knowing these codes speeds up the quote and prevents mounting errors.
In Argentine industry, these housings are used in conveyor belts, mixers, fans, centrifugal pumps and agricultural machinery. Their 4-bolt flange allows firm fastening onto sheet metal or profile structures, and the insert with set screws makes adjustment onto commercial shafts easy. They are common in food plants, cement plants, tanneries and maintenance workshops looking for durable spare parts that are simple to replace.
To select the housing, check the shaft diameter and the type of load: radial, axial or combined. The D1 sealing protects against dust and splashes, suitable for damp or dirty environments. During mounting, make sure the support surface is flat and clean; tighten the set screws on the inner ring with the appropriate wrench and check shaft alignment before lubricating. Periodic lubrication with lithium grease extends the service life of the insert.
NTN UCFX housings are interchangeable with other brands that follow the mounted bearing standard, such as SKF, FAG or NSK, as long as the flange dimensions and shaft diameter match. When replacing, compare the distance between holes and the insert diameter. If in doubt, the original code printed on the housing is the safest reference for finding the exact equivalent.
