The NSK UC2 series insert bearing is a ball bearing with a spherical outer ring and set screws, designed to be mounted in split or solid housings. It is used in equipment where the shaft rotates and needs flexible alignment, such as conveyor belts, mixers or fans. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and quotes it on WhatsApp with the exact part number.

The UC series designation is read as follows: UC indicates an insert bearing with set screws, the number that follows corresponds to the shaft diameter (16 mm for UC201, 17 mm for UC202, etc.), and the D1 suffix indicates a manufacturer's sealing and tolerance variant. The suffix with a hyphen in the codes identifies the size in inches. With this data you can choose the insert that corresponds to your shaft.

These bearings are used in the food, chemical, textile and transport industries in Argentina. They are mounted in split or flange housings for shafts of conveyor belts, bucket elevators, mixers, dryers and fans. Their spherical outer ring compensates for small misalignments between the housing and the shaft, which simplifies mounting and reduces maintenance in equipment with vibrations or moderate loads.

To select the insert, take into account the shaft diameter, the housing type and the environmental conditions. The D1 sealing protects against dust and humidity, but if there are frequent washdowns or exposure to liquids, it is advisable to verify the seal type. The set screws must be tightened with the proper wrench and with clean threads; poor locking causes premature wear. Factory lubrication is usually sufficient, but in demanding applications relubrication with compatible grease is recommended.

As for equivalences, UC2 insert bearings from different brands share main dimensions, but the sealing, set screws or surface treatment may vary. If you bring another brand's part number or an unidentified part, at MR Accesorios Industriales we will indicate the compatible alternative. We work with the exact designation that appears on the housing or on the old bearing to ensure the correct replacement.
