This NTN UELC series cartridge unit combines a housing and an insert bearing, sized to press into a cylindrical seat. It provides compact radial support where sealing against dust or moisture matters, and it mounts with the shaft already positioned. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams across the United States and Latin America, and can help confirm the size before you order.
Reading the code helps you order the right piece. The letters UELC denote the cartridge housing with insert bearing. The first group of digits, such as 204, 205 or 206, gives the nominal shaft diameter in millimeters. The suffixes D1 and W3 describe sealing and insert variants. So UELC204-012D1W3 and UELC204D1W3 share a shaft size, while UELC205-013D1W3 and UELC205-100D1W3 show two ways of writing the same size class. The full part number is what identifies the exact unit.
Typical applications include conveyors, belt systems, elevators, mixers, fans and process equipment that needs a compact support protected from contamination. Food, cement, ceramic and packaging operations often choose this design because washdown or airborne dust puts a premium on reliable sealing.
When selecting, check shaft diameter, load type (radial, axial or combined) and the operating environment. The D1 seal and W3 configuration set the level of protection. Installation calls for a cylindrical seat with the right tolerance, proper alignment and lubrication matched to the duty cycle. Do not strike the insert during fitting, and verify clearance after tightening.
NTN mounted bearings can interchange with other brands that follow equivalent standards, provided the dimensions and fastening style match. If you only have another brand's number or an unmarked part, send it over and we will point you to the compatible option. We can also quote the exact size you need.
