How to choose and quote HIWIN crossed roller bearings

HIWIN is a brand of linear motion components and special bearings. In Buenos Aires, Argentina, from MR Accesorios Industriales we supply and distribute its products for different industrial applications. We work with the special bearings line, which includes models such as CRBA 25025, CRBB 15025 and CRBA 10020. These bearings are used in equipment that requires precision and load support in rotary or linear movements.

HIWIN special bearings differ from standard bearings by their design oriented to specific applications. For example, the CRBA and CRBB models correspond to crossed roller bearings, which combine rigidity and load capacity in a reduced space. They are used in rotary tables, robot axes, medical equipment and precision machinery. When quoting, it is key to indicate the exact code engraved on the part or the main dimensions.

To request a quote, you can send us the bearing code or a photo of the part with the dimensions. We supply the HIWIN brand and quote the model you need. If you have an equivalent code from another brand, you can also send it so we can indicate the corresponding alternative. We review the data and reply promptly.

Within HIWIN special bearings, crossed rollers occupy a central place: the rollers alternate at right angles between the raceways, so that a single bearing receives radial, axial and moment loads. In industry they are used in machining centers, indexing tables, robotic arms and automation equipment. The model CRBA 25025 is an example of a crossed roller bearing of the CRBA series.

Each HIWIN code identifies the series and the size: CRBA and CRBB are crossed roller series, and the numbers that follow define the bearing dimensions. That is why CRBA 10020 and CRBA 25025 belong to the same series but do not have the same size. It is important to verify the complete code on the part, since a change in a number or a letter corresponds to another bearing.

When selecting a special bearing, the radial and axial load, rotation speed and working environment must be considered. Crossed rollers support loads in several directions with high rigidity, which is why they are chosen for precise rotary movements. At MR we help you identify the correct model from the code or the dimensions. Send us the information by WhatsApp or email and we will quote the HIWIN bearing you need.

HIWIN bearings have an alphanumeric code engraved that allows them to be identified precisely. For example, CRBA 25025 indicates a CRBA series with specific dimensions. The letters identify the series and the numbers, the size. Since the format can vary between series, the safest thing is to take the code exactly as it appears on the part and not interpret it by eye.

In the case of CRBB 15025, the CRBB series is also a crossed roller series, but it is a different series from CRBA. To avoid errors, we recommend copying the complete code exactly as it appears on the part, including spaces and hyphens if any. If the code is blurry, you can measure the inner, outer diameter and width with a caliper and send us those dimensions.

In addition to the code, it is useful to indicate the brand and the equipment where the bearing is mounted. That allows us to confirm the model and quote the correct HIWIN bearing. We supply the brand and distribute its special bearings in Argentina. If you have doubts about the nomenclature, send us a photo and we will help you identify the model.

HIWIN special bearings are installed in equipment that demands precision and durability. In the metalworking industry, they are used in rotary tables of machining centers and in milling heads. In automation, they appear in industrial robots and rotary actuators. They are also used in positioning tables and inspection equipment.

These bearings also appear in machines in food, pharmaceutical and packaging plants, where rotary movements must be smooth and precise. In an indexing table, for example, a crossed roller bearing such as CRBA 25025 can replace a pair of bearings and simplify the design.

To choose the correct bearing, the application must be analyzed: type of movement, loads present and environmental conditions. HIWIN crossed rollers offer rigidity and precision, but each series has its load and speed limits. At MR we advise you according to your equipment and quote the appropriate model. Send us the machine data and the code of the current bearing.

The HIWIN CRBA and CRBB series are crossed roller bearings, but each has its own construction. Both are used in high-precision applications, and from the outside two bearings of different series can look very similar. That is why the letter in the code is as important as the numbers.

The model CRBA 10020 belongs to the CRBA series and CRBB 15025 to the CRBB series: in addition to the letter, the numbers change, that is, the size. When quoting, it is essential to indicate the exact series, since they are not interchangeable in all cases. An error in the letter can result in a bearing that does not fit.

If you are not sure which series corresponds to your equipment, send us a photo of the current bearing or the dimensions. We supply both series and indicate the correct option according to your application. You can also inquire about equivalent bearings if you have the code from another brand. We review the data and reply promptly.

To quote a HIWIN bearing, you can write to us by WhatsApp or email with the exact code of the part. For example, if you need CRBA 25025, send us that code and we will send you the quote. If you do not have the code, you can measure the inner, outer diameter and width, and send us those dimensions along with a photo. It is also useful to indicate the brand and the equipment where it is mounted.

We work with the HIWIN brand and distribute its special bearings in Argentina. Upon receiving your inquiry, we review the code and quote the HIWIN bearing. If you have a code from another brand, you can send it so we can indicate the corresponding HIWIN alternative. It is not necessary to send us the physical bearing to quote.

Avoid common mistakes when ordering: do not copy only part of the code, do not confuse similar series and do not omit the letters. An incomplete code can lead to an incorrect quote. At MR we help you identify the correct model and reply promptly. Send us your inquiry today and receive the quote for your HIWIN bearing.

One of the most frequent mistakes is ordering a bearing only by dimensions, without verifying the code. Two bearings with the same diameter can have different construction and load capacity. For example, CRBA 25025 and CRBB 15025 are not interchangeable even though they look similar. It is always better to send the complete code engraved on the part.

Another common mistake is not considering the mounting conditions. Crossed roller bearings require precise fitting and adequate lubrication. Forced mounting can damage the raceways. When installing, follow the manufacturer's recommendations and use appropriate tools. If you have doubts, consult us before mounting.

You should also avoid confusing series or brands when looking for spare parts. If you have an original HIWIN bearing, order the same code. If you have an equivalent from another brand, send us the code and we will indicate the HIWIN alternative. At MR we supply and distribute the brand, and quote the correct product for your equipment.
