For tight radial spaces where a standard bearing will not fit, MCGILL MR RS series needle bearings provide a compact solution. The RS suffix means the bearing includes seals, which keep lubricant in and contaminants out. These bearings handle radial loads in transmissions, machine tools, lifting equipment and other industrial machinery that demands precision and durability.
The code follows a simple pattern: MR identifies the series, the following number relates to size, and RS confirms the presence of seals. In part numbers like MR 10 RS, MR 12 RS and MR 14 RS, the number changes to match different dimensions. When selecting a bearing, you need to match the shaft diameter, outer diameter and width to your mounting.
These bearings appear in gearboxes, pumps, compressors, packaging lines, material handling systems and roller assemblies. Their low profile suits equipment where radial space is limited but rigidity is still required. In continuous production environments, the combination of needle rollers and seals helps reduce maintenance needs.
Selection should consider radial load, speed and operating conditions. The RS seal guards against dust and moisture, but in high-temperature or high-speed applications, check lubrication and internal clearance. Install with proper tools, avoid hitting the seals, and ensure correct alignment between shaft and housing. Clean lubrication and proper fit prevent early failures.
Needle bearings are standardized by their dimensions, so different brands can be interchangeable when inner diameter, outer diameter and width match. A similar code alone is not enough; compare the dimensional data and seal type. For replacement, the safest reference is the code engraved on the old bearing or measurements taken with a caliper.

Frequently asked questions
- What does the RS suffix indicate on MR bearings?
- RS means the bearing has integral seals. These seals keep dust, dirt and moisture out while retaining lubricant, which helps extend service life in contaminated conditions. Always confirm that the seal material suits your operating speed and temperature.
- How do I select the correct code in the MR RS series?
- You need the shaft diameter, outer diameter and width of the mounting. The number after MR is chosen based on these dimensions. If you have the old bearing, the engraved code or caliper measurements are the best reference for ordering a replacement.
- Can MCGILL MR RS series bearings be replaced with other brands?
- Yes, if the standardized dimensions and seal type match. Interchangeability depends on measurements, not just the code. Compare technical data sheets or contact us with your exact measurements for guidance.
