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 flexible alignment is needed, such as conveyor belts, mixers or fans. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and quotes it via WhatsApp with the exact part number.
The UC2 series designation is read as follows: UC indicates an insert bearing with set screws, 2 corresponds to the shaft diameter in inches (16 mm for UC201, 17 mm for UC202, etc.), and the suffix D1 indicates a manufacturer's sealing and tolerance variant. For example, UC201-008D1 has a shaft diameter of 1/2 inch, while UC201D1 is the same size in millimeters. The suffix -008 in codes with a hyphen identifies the inch size. With this data you can choose the insert that matches your shaft.
These bearings are used in the food, chemical, textile and transport industries in Argentina. They are mounted in split or flanged housings for conveyor belt shafts, 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 on equipment with vibration or moderate loads.
To select the insert, take into account the shaft diameter, the housing type and the environmental conditions. The D1 seal protects against dust and moisture, but if there is frequent washdown or exposure to liquids, it is advisable to check the seal type. The set screws must be tightened with the right wrench and with clean threads; poor fastening causes premature wear. Factory lubrication is usually sufficient, but in demanding applications relubrication with compatible grease is recommended.
As for equivalents, UC2 insert bearings from different brands share main dimensions, but the sealing, set screws or surface treatment may vary. If you bring the part number from another brand or an unidentified part, at MR Accesorios Industriales we point you to the compatible alternative. We work with the exact designation shown on the housing or on the old bearing to ensure the correct replacement.

We can also advise you if you have questions about mounting or lubrication. MR Accesorios Industriales has more than 80 years of experience in bearings and power transmission.

Frequently Asked Questions
- What does the D1 suffix mean on UC2 bearings?
- The D1 suffix identifies a sealing and tolerance variant within NSK's UC2 series. It does not change the bearing's main dimensions, but it can affect protection against contaminants. If your application has a lot of dust or moisture, consult us via WhatsApp and we will advise you.
- How do I know what shaft size I need for my housing?
- Measure the shaft diameter where the bearing is mounted. In the UC2 series, the number after UC indicates the diameter in millimeters (for example, UC204 for 20 mm). If the code has a hyphen, such as UC204-012, the size is in inches. If you have doubts, send us a photo or the old part number.
- Can I replace an insert bearing from another brand with an NSK one?
- In general, UC2 insert bearings are interchangeable between brands because they share main dimensions. However, the sealing or set screws may vary. Bring us the part number of the original part or the dimensions and we will tell you the exact equivalent via WhatsApp.
