The MCGILL MI series needle roller bearing is a component with a very small radial section, designed to withstand radial loads in spaces where a ball or roller bearing will not fit. It is used in machine tools, transmission equipment and mechanisms that need 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 marked on the part.

The MI series designation is read in blocks: the letters identify the needle roller bearing family, the first number indicates the shaft or bore diameter depending on the case, and the final number defines the width or the sealing variant. The S suffix appears as an indicator of a version with sealing or lateral protection. To request a quote, send us the complete code exactly as it appears on the part or in the drawing.

This type of bearing is used in industries in Argentina 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 withstand radial loads with a low profile makes it common in gearboxes and in joints that require oscillating movement rather than continuous rotation at high speeds.

To select the correct bearing, take into account 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 raceway. 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.

As for equivalents, needle roller bearings are identified by standardized dimensions, but each manufacturer uses its own nomenclature. An MCGILL MI code is not directly replaced by that of another brand without verifying diameter, width and type of seal. If you need an alternative, send us the actual dimensions or the original code and we will review the interchangeability.

MR Accesorios Industriales sells the MCGILL brand as part of its bearing line. If you are looking for an MI series needle roller bearing, write to us on WhatsApp with the code or the shaft and housing dimensions. We will reply shortly with the option that best suits your equipment.
