The MCGILL MI series needle roller bearing is a component with a very small radial section, designed to support radial loads in spaces where a ball or roller bearing does not fit. It is used in machine tools, transmission equipment and mechanisms that require precise rotation with a small outer diameter. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and helps you identify the exact size from the code engraved on the part.

The designation of the MI series is read in blocks: the letters identify the needle roller bearing family, the first number indicates the shaft or bore diameter as applicable, and the final number defines the width or seal variant. In the examples MI 22 4S, MI 25 4S and MI 26 2S, the S suffix appears as an indicator of a sealed or side-protected version. To request a quote, send us the complete part number as it appears on the part or drawing.

This type of bearing is used in Argentine industries where radial space is critical: machine tools, presses, packaging equipment, chain and belt drives, and lifting mechanisms. It also appears in pumps, compressors and textile equipment. Its ability to support radial loads with a low profile makes it common in gearboxes and in joints that require oscillating motion rather than continuous high-speed rotation.

To select the correct bearing, consider the shaft diameter and tolerance, the available width and the type of load. The MI series can be mounted directly on the shaft if it is ground and has adequate hardness, or on a separate inner race. The S seal protects against dust and moisture, but requires compatible lubrication. Alignment between shaft and housing is key: excessive misalignment shortens the service life of the needles.

Regarding equivalences, needle roller bearings are identified by standardized dimensions, but each manufacturer uses its own nomenclature. An MCGILL MI part number cannot be directly replaced by another brand without verifying diameter, width and seal type. If you need an alternative, send us the actual dimensions or the original part number and we will review interchangeability.

MR Accesorios Industriales has more than 80 years in the industry and sells the MCGILL brand as part of its bearing line. If you are looking for an MI series needle roller bearing, write to us via WhatsApp with the part number or the shaft and housing dimensions. We will reply shortly with the option that best fits your equipment.
