The NTN UELC series cartridge housing is a mounted bearing with a roller insert, designed to fit into cylindrical housings or seats. It is used when the transmission needs a compact radial support that is easy to mount, with built-in sealing for dusty or humid environments. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you on choosing the correct size for your application.

The UELC designation is read in blocks: UELC identifies the cartridge housing with insert bearing; the number that follows (204, 205, 206…) indicates the nominal shaft diameter in the metric system. The D1 and W3 suffixes correspond to sealing and insert configuration variants. For example, UELC204-012D1W3 and UELC204D1W3 share the same shaft diameter, while UELC205-013D1W3 and UELC205-100D1W3 show different ways of expressing the size. With the complete part number we can identify the exact part.

These housings are used in conveyors, belts, elevators, mixers, fans and process equipment where the support must be compact and resistant to contamination. In Argentina they are found in food, cement and ceramic plants and in packaging lines, where washing or dust demand reliable sealing.

To select the housing, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The D1 sealing and the W3 configuration define the protection against dust and humidity. Mounting requires a cylindrical seat with adequate tolerance, correct alignment and lubrication according to the duty cycle. Avoid striking the insert during installation and check the clearance after tightening.

NTN mounted bearings are interchangeable with those of other brands under equivalent standards, as long as dimensions and fastening type match. If you bring the part number of another brand or an unidentified part, at MR Accesorios Industriales we will indicate the compatible alternative. We can also quote the exact size you need.
