When a shaft needs support but the surrounding space is too tight for a conventional bearing, the MCGILL MI series needle roller bearing is often the answer. Its very small radial cross-section lets it carry radial loads in compact assemblies such as machine tools, power transmission equipment and mechanisms that rotate continuously or oscillate. MR Industrial Accessories supplies this line and helps you match the right size to your shaft and housing.
The MI designation marks a family of needle roller bearings; the letters stay the same and the number that follows sets the size within the range. Models such as MI 6, MI 8, MI 10, MI 12, MI 13, MI 14, MI 15 and MI 16 step up through the available options. Because the code alone does not tell you every dimension, send the full model number and we will check it against the technical data.
Typical installations include spindles, cams, pumps, compressors, industrial sewing machines and power transmission components, plus low-speed oscillating mechanisms. They suit metalworking, food processing, plastics and woodworking operations. The common thread is a small outside diameter that still has to handle a demanding radial load.
Three dimensions drive selection: shaft diameter, housing bore and the width you have to work with. Also confirm how the assembly protects the bearing, since the needles do not tolerate contamination well. Lubrication has to be right and shaft-to-housing alignment has to be accurate. In oscillating motion, verify that lubricant reaches every needle. Send us the code if you want help.
Needle roller bearings follow dimensional standards that several manufacturers share, so one size can carry different commercial codes from brand to brand while the shaft, outside and width dimensions stay the same. Before substituting anything, confirm those dimensions and the cage style. Give us the original code and we will look for a compatible option.
MCGILL is one of the bearing brands we supply. If you already know the MI code you need, send it over WhatsApp and we will prepare your quote. If you only have the shaft and housing measurements, we can help you identify the size.

Frequently asked questions
- What does the MI series indicate in a MCGILL bearing?
- MI identifies a family of needle roller bearings with a small radial section. The number after the letters sets the size or main dimension of the assembly. Send us the complete model and we will confirm the exact figures for that code.
- What information do I need to pick the right needle roller bearing?
- Shaft diameter, housing diameter and available width are the starting point. The type of motion, the load and the operating environment also affect the choice. With those details we can point you to the MI model that fits.
- Can a MCGILL needle roller bearing be replaced by another brand?
- Many needle roller bearings use standardized dimensions, so equivalents exist across manufacturers. Cage design, sealing and tolerances can still differ between brands. Send us the original code and we will check the dimensions and propose a compatible alternative.
