The NSK REL series insert bearing is a ball bearing with an extended inner ring and a locking system, designed to be mounted in split plummer block housings, pillow block units and wall housings. It is used where the shaft rotates and a compact, self-aligning and easy-to-replace unit is required. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and quotes the exact part number on WhatsApp.
The REL series designation is read in blocks: the letters identify the insert family and the number that follows indicates the shaft diameter. The suffixes that appear after the number describe variants of the part: for example, in REL204-012W3 the final segment refers to a shaft size with its own code, while in REL205-013W3, REL205-014W3 and REL205-015W3 that numeric suffix changes for different sizes within the same base diameter. The W3 ending distinguishes a construction variant of the series. To choose correctly, send the full part number exactly as it appears on the housing or on the old part.
These inserts are found in belt conveyors, packaging lines, mixers, blowers, exhausters and process lines in food, chemical and materials plants. In Argentina they appear frequently in grain handling equipment, in the meat processing industry and in aggregate processing plants, where the environment is humid or dusty and maintenance is done with the equipment stopped for the shortest possible time. They are also used in agricultural machinery and in low and medium power pumping equipment.
To select the insert, take into account the shaft diameter, the type of inner ring locking and the sealing required by the environment. In dusty or wet applications a tighter seal is advisable; on shafts rotating at higher speed, check the clearance and the pre-applied lubrication. When mounting, seat the insert in the housing without striking the outer ring, align the shaft with the housing and tighten the locking evenly. Poor alignment accelerates wear and generates noise.
Interchangeability between brands is handled by part number and by dimensions: an insert from another brand with the same basic designation and the same shaft diameter is usually interchangeable, but the sealing and locking suffixes vary between manufacturers. If you bring an unidentified part or the part number of another brand, at MR Accesorios Industriales we tell you the compatible alternative and quote the exact size you need.
To move forward, send us on WhatsApp the full insert part number, the shaft diameter or a photo of the part and the housing. With that we quote you promptly. If you are looking for a variant of the REL series that you do not see listed, write to us anyway with the model you need: we will source it for you.

Frequently Asked Questions
- What does the W3 suffix mean on a REL insert?
- The W3 suffix identifies a construction variant within the REL series. It does not change the shaft diameter, which is in the base number, but the sealing or the type of locking may vary. Send the full part number to quote the correct version.
- How do I choose between REL204 and REL205?
- The base number is associated with the shaft diameter: the 204 and 205 series correspond to different sizes. Check the shaft diameter and the part number marked on the insert or on the housing. With that data we quote the exact size.
- Can an insert from another brand be replaced by an NSK REL series insert?
- In many cases yes, by comparing shaft diameter, inner ring width and type of locking. Sealing suffixes may vary between manufacturers. If you send us the part number of the original part, we tell you the compatible alternative.
