The NTN SESPA series Y-bearing 2-bolt flange unit is a mounted bearing with a 2-bolt flange, designed to secure rotating shafts to flat structures simply and compactly. It is used in equipment where radial loads and some axial thrust need to be supported, with self-alignment thanks to the insert's spherical seat. It is a common solution in light and medium transmissions, and MR Accesorios Industriales sells it in Buenos Aires, Argentina.

The SESPA series designation reads as a housing unit with an insert bearing. The letters indicate the type of housing and the locking system, while the numbers that follow identify the insert and shaft size. For example, SESPA201 corresponds to an insert for a 12 mm shaft, SESPA202 for 15 mm, SESPA203 for 17 mm, SESPA204 for 20 mm and SESPA205 for 25 mm. Suffixes with a hyphen, as in SESPA204-12 or SESPA205-16, indicate inch diameter variants. Learn more about this series and its applications by consulting MR.

These units are used in a wide variety of industries in Argentina: from packaging and material handling lines to agricultural machinery, bakery equipment, industrial laundries and ventilation systems. Their two-bolt flange allows them to be mounted on folded sheet metal, profiles or concrete beds, and their insert with a spherical seat absorbs small misalignments. They are common in applications where the shaft rotates at moderate speeds and loads are not extreme, and where quick and economical mounting is sought.

To select the correct unit, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The insert's sealing protects against dust and moisture; in environments with liquids or fine particles, versions with an additional seal should be chosen. Factory lubrication is usually sufficient for the entire service life, but in demanding applications it can be relubricated. Mounting requires that the support surface be clean and flat, and that the fastening screws be tightened evenly to avoid deformation. Initial alignment is important, although the insert's spherical seat compensates for minor deviations.

As for equivalents, Y-bearing units from different brands usually share standardized dimensions, which allows them to be interchanged if the shaft diameter and flange dimensions match. However, not all part numbers are directly replaceable: always verify the mounting dimensions and the insert's locking type. If you have the part number of another brand or an unidentified part, at MR we will tell you the compatible alternative or quote the exact size you need.
