When a machine design leaves little room in the radial direction but still demands stiffness and accurate rotation, a needle roller bearing is often the answer. The MCGILL MR series is built around small-diameter cylindrical rollers, which let it support substantial radial loads inside a slim cross-section. MR Industrial Accessories supplies this line and can help you match the bearing to your shaft and housing dimensions.

The part number itself carries useful information. MR identifies the series, and the number after it gives the nominal size of the bearing: MR 10, MR 12, MR 14, MR 16, MR 20, MR 22 and MR 24 each correspond to a different shaft or inner raceway diameter. If the full code includes extra letters, those refer to design details such as the sealing arrangement or the raceway configuration. Send us the complete part number and we can clarify what those suffixes mean.

Typical applications include machine tools, pumps, compressors, electric motors, transmissions, packaging lines and linear motion systems. The same qualities that suit these machines also make the MR series useful on forklifts, cranes, road equipment and agricultural machinery, especially in joints, cams, support rollers and guides where a larger bearing would not fit.

Choosing the right bearing starts with the radial load, the rotational speed, the lubrication method and the operating environment. During mounting, cleanliness and correct alignment between shaft and housing are essential, and the raceway must have the right hardness and surface finish. In dusty or damp conditions, sealed variants help keep contaminants out. Grease or oil can be used for lubrication, with renewal intervals set by your maintenance plan.

Bearings from different manufacturers can often be exchanged when the bore diameter, outer diameter and width match. Even so, it is not enough to compare dimensions alone: load capacity, cage design, sealing and tolerances also need to be checked. For a replacement, the most reliable approach is to compare the full technical data and speak with a specialist.

To request a quote for an MCGILL MR series needle roller bearing, send the part number or the size you need by WhatsApp or email. We will help you confirm the correct variant and can also assist in identifying a replacement if you provide the dimensions of the original bearing.
