The MCGILL MR S series needle bearing is a reduced section radial bearing, with a machined outer ring and needles as rolling elements. It is used when there is little radial space and moderate loads, and where high load capacity is needed in a compact diameter. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you so that you choose the part number that corresponds to your application.

The MR S series designation is read by the number that follows the letters: for example, MR 10 S, MR 12 S or MR 16 S. That number identifies the bearing size within the series and correlates with the shaft or housing diameter, depending on the case. The S suffix distinguishes a construction variant within the family. To select the exact part number, have the shaft and housing measurements on hand, and send us the complete part number via WhatsApp.

This type of needle bearing is used in applications where radial space is limited and loads are mainly radial. It is common in machine tools, transmission equipment, pumps, compressors, agricultural machinery and material handling equipment. In Argentina, you find it in production lines, industrial maintenance and machinery manufacturing. Its design makes it possible to reduce the size of the assembly without sacrificing load capacity.

To select the correct bearing, verify the shaft diameter, the housing diameter and the width. If the bearing does not have a built-in seal, consider adding radial shaft seals or seals depending on the environment. Proper lubrication and alignment of the supports are key to avoiding premature wear. In assemblies with interference fit, follow the recommended procedure so as not to damage the needles or the raceways.

Needle bearings from different brands may be interchangeable if the main dimensions and the type of execution match. It is not enough for the part number to be similar: inner diameter, outer diameter, width and type of sealing must be compared. If you have doubts, consult us with the original part number and the measurements. At MR Accesorios Industriales we help you find the right equivalent.

If you already have the part number MR 10 S, MR 12 S or any other in the series, send it via WhatsApp to MR Accesorios Industriales along with the measurements of your assembly. That way we can confirm the variant and send you the quote promptly. We also handle inquiries for other brands and types of needle bearings.
