How to Choose IKO Cylindrical and Cam Followers: Uses, Codes, and Quotes

IKO is a Japanese brand specialized in needle bearings and precision rollers. In Argentina, at MR Accesorios Industriales we distribute its main lines for maintenance and replacement. IKO products stand out for their compact design and load capacity in tight spaces.

Within IKO's offering, we work with two main subcategories: cylindrical rollers and cam and support rollers. Each responds to different needs for linear or rotary motion. Example codes such as NAS 5019UUNR or NART 5 UUR / SG allow identifying the exact model.

To quote an IKO product, the most practical is to send the code engraved on the part or, if it cannot be read, the main dimensions. With that we indicate the correct alternative and send you the quote shortly. You can also send a photo of the part to facilitate identification.

IKO cylindrical rollers are cylindrical roller bearings designed to withstand high radial loads. They are used in shafts, pulleys, and mechanisms where firm, low-friction support is needed. The NAS series is one of the most requested within this line.

In Argentine industry they appear in machine tools, printing equipment, conveyor systems, and textile machinery. They are also used in tension and support rollers in continuous production lines. Their robust construction allows maintaining precision under constant loads.

When ordering an IKO cylindrical roller, it is advisable to verify the complete code, such as NAS 5016ZZNR or NAS 5034ZZNR. If there is no visible code, measure inner diameter, outer diameter, and width.

IKO cam and support rollers, also called cam followers, combine a central stud with a thick outer ring. They are designed to follow cam profiles, guides, or raceways in linear motion. They support radial loads and, depending on the design, also minor axial loads.

They are used in industrial automation, coordinate tables, transfer systems, and packaging machinery. They also appear in cutting, bending, and forming equipment where a roller must slide over a surface. Within this line are also NART support rollers, such as NART 5 UUR / SG, which do not have a stud and are mounted on their own shaft.

To quote an IKO cam or support roller, send the complete code, for example NART 8 UUR / SG. If it cannot be distinguished, measure the outer diameter, total width, and stud or hole diameter, depending on the model. A photo of the part helps confirm the seal type and end configuration.

IKO codes follow a series and size logic. For example, in NAS 5019UUNR, the number 5019 indicates the size. It is important to copy the code exactly as engraved on the ring or stud.

If the code is blurry or illegible, it can be identified by dimensions. For a cylindrical roller, inner diameter, outer diameter, and width are needed. For a cam roller, stud diameter, outer diameter, and total width; for a support roller without stud, inner diameter, outer diameter, and width. With that data, at MR we help you find the equivalent model.

A common mistake is omitting suffixes or confusing similar series. For example, NAS 5016ZZNR and NAS 5034ZZNR are different sizes even though they share the ending. It is always advisable to verify the central number and final letters before ordering. If you have doubts, send us a photo and we will confirm it.

One of the most common mistakes is ordering a roller by approximate dimensions without considering the seal type or cage. A protected roller is not interchangeable with an open one if the application requires protection against contamination. Nor should one assume that an eccentric stud cam roller works for concentric mounting without verifying.

During mounting, it is key to respect housing and shaft tolerances. Too tight a fit can damage the outer race or block rotation. In cam rollers, the stud tightening torque must be the one indicated by the manufacturer to avoid play or breakage.

Another frequent mistake is not verifying initial lubrication. Some IKO rollers come with factory grease, but in high-frequency applications it is advisable to relubricate according to the maintenance plan. If you are not sure of the correct model, send the code or dimensions and at MR we advise you before purchase.

IKO rollers are present in a wide variety of industries in Argentina. In metalworking they are used in machine tool guides and feed systems. In the food industry they appear in conveyors and packaging equipment where cleanliness and precision are required.

In the textile sector, cylindrical and cam rollers work in looms and stamping machines. In the printing industry, they support printing and folding rollers. They are also seen in automation and robotics, where cam followers guide repetitive movements with high accuracy.

Each application requires a specific type of roller. That is why it is important not to replace one model with another just because of similar dimensions. At MR we work with IKO lines so you get the exact replacement, whether a cylindrical roller or a cam roller, according to the equipment and function. If you have several replacements for the same machine, send the complete list and we will prepare a single quote with all codes.

To quote an IKO roller, send via WhatsApp or email the complete code, for example NAS 5019UUNR or NART 5 UUR / SG. If you do not have the code, send us the dimensions and a photo of the part. With that information we indicate the correct model and send you the quote shortly.

We work with buyers and maintenance managers from all Argentine industry. Our location is Buenos Aires, Argentina, and we distribute genuine IKO products. When ordering, it is advisable to specify the quantity and application to ensure the right choice.

You do not need to look up equivalents on your own: if you have the code from another brand, we analyze it and propose the corresponding IKO. Write to us today with your roller data and we will coordinate the quote without delay.
