The UELC housing is a cartridge mounted bearing unit: a ready-to-mount unit that combines an insert bearing with a cast iron housing. It is used to support rotating shafts in equipment where simple fixing and good sealing are required. The NSK UELC series is characterized by its cartridge design, which allows it to be mounted directly onto the machine structure. MR Accesorios Industriales sells this line for industrial applications in Buenos Aires, Argentina.
The UELC series designation is read in parts. The letters UELC identify the cartridge housing type with insert bearing. The numbers that follow indicate the shaft diameter: for example, UELC204 corresponds to a 20 mm shaft, UELC205 to 25 mm and UELC206 to 30 mm. The suffixes D1 and W3 refer to sealing and housing configuration variants. In the hyphenated examples, such as UELC204-012D1W3, the number after the hyphen indicates an inch measurement. Thus, UELC204-012D1W3 is equivalent to a 3/4 inch shaft. Knowing this logic lets you quickly identify the unit you need.
These housings are used in conveyors, belts, elevators, mixers, fans and agricultural machinery. In Argentina, they are common in food plants, cement plants, quarries and agro-industrial facilities. Their cartridge format makes mounting on walls or sheet metal structures easy, with two or four fixing holes. Because they are self-aligning units, they tolerate small misalignments and simplify maintenance. If your equipment works with dust, moisture or frequent washdowns, this type of housing with reinforced sealing is a common option.
To select the correct housing, take into account the shaft diameter, the type of load and the environmental conditions. Check that the insert bearing has the right sealing: the D1 and W3 suffixes indicate specific seal configurations that improve protection against contaminants. During mounting, make sure the support surface is clean and flat, and that the fixing screws are properly tightened. Factory lubrication is usually sufficient, but in demanding environments it is advisable to check the condition of the grease periodically. Careful alignment extends the service life of the assembly.
NSK UELC housings can be interchanged with equivalent units from other brands that follow the same dimensional nomenclature. If you are replacing an existing housing, note the complete code and the shaft dimensions to ensure compatibility. At MR Accesorios Industriales we advise you to find the unit that best suits your equipment. If you cannot find the exact reference, write to us on WhatsApp with the code or model you need and we will quote it for you shortly.
