The NTN SES series insert bearing is a ball bearing with an extended inner ring, designed to be mounted in split plummer block housings and bearing units. Its design allows the shaft to be secured with set screws and compensates for minor misalignments. It is used in power transmission equipment, conveying systems and general machinery, where a compact and easy-to-mount solution is required. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, with more than 80 years of experience in the field.

The SES series designation reads as a code combining letters and numbers. The letters SES identify the insert bearing series with extended inner ring and set screw locking system. The numbers that follow indicate the bore diameter and the bearing size: for example, SES201 corresponds to a 12 mm bore, SES202 to 15 mm, SES203 to 17 mm, SES204 to 20 mm, SES205 to 25 mm and SES206 to 30 mm. In some cases, such as SES204-12 or SES205-16, the numeric suffix after the hyphen indicates an inch measurement (for example, 3/4" or 1"), which allows the bearing to be adapted to shafts with imperial measurements.

These insert bearings are used in a wide variety of industrial applications in Argentina. They are found in belt conveyors, bucket elevators, mixers, fans, pumps, agricultural machinery and process equipment. They are also common in the food, cement, mining and aggregate processing industries. Their ability to support radial loads and moderate axial loads, together with their ease of mounting, makes them suitable for equipment where simple maintenance and quick replacement are required.

To correctly select an SES series insert bearing, take into account the shaft diameter, the type of housing and the operating conditions. Verify that the bore matches the shaft size, whether metric or imperial. Consider the sealing: these bearings usually incorporate lip seals that retain lubricant and exclude contaminants. Lubrication is essential; many models come pre-lubricated and allow relubrication through a passage in the outer ring. During mounting, ensure proper alignment and tighten the set screws onto the shaft with the recommended torque to prevent slipping.

Regarding equivalences and interchangeability, NTN SES series insert bearings can be replaced by products from other brands that follow the same dimensional nomenclature. Equivalents are commonly found in lines such as SKF YAR, FAG 162, NSK RLS or Timken GY, provided the bore diameter, outer dimensions and locking type match. However, tolerances and materials may vary between manufacturers, so it is advisable to verify compatibility before replacing. If you have any doubts, ask us with the original part number and we will advise you.
