A needle roller bearing needs a hard, finely finished surface to run on. When the shaft itself cannot provide that, an SKF LR series inner ring supplies the raceway instead. It presses onto the shaft as a separate, replaceable component, so the bearing needles roll on a surface built for the job. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams across the United States and Latin America.
The part number tells you the size before you open a catalog. In a designation such as LR 15X18X12.5, the three figures are millimeter dimensions in sequence: bore 15 mm, outside diameter 18 mm, width 12.5 mm. Suffixes that follow the basic number identify variations in machining or surface treatment, so confirm them against the data sheet before you commit to a replacement.
Use an inner ring whenever the shaft is too soft or too rough to act as a raceway on its own. Typical installations include agricultural equipment, gearboxes and transmission assemblies, pumps, compressors, machine tools and conveying systems. Repairing or modifying an existing assembly with an inner ring is often more practical than replacing a shaft.
Selection comes down to three points: shaft diameter, bearing width and the load the assembly carries. The raceway has to be hard enough and smooth enough, which is why SKF rings are heat treated and precision ground. At installation, check alignment with the bearing and keep impacts away from the raceway surface. Use a lubricant compatible with the rest of the assembly and renew it on your maintenance schedule.
Standard dimensions make LR series rings interchangeable between brands, but tolerances, hardness and surface finish can differ. Compare dimensions and operating conditions before substituting one for another. If anything is unclear, send the complete part number and a description of the application; our team can suggest equivalents and help you choose. Requests for quotes come through WhatsApp or email, and we reply promptly.
To request a quote, send the part number by WhatsApp or email. If the number is not at hand, the shaft and bearing dimensions are enough for us to help identify the correct ring.

Frequently asked questions
- What do the numbers in LR 15X18X12.5 indicate?
- They are millimeter dimensions in order: 15 mm bore, 18 mm outside diameter and 12.5 mm width. Reading the code this way lets you match the ring to your assembly quickly.
- Will an SKF LR inner ring fit any needle roller bearing?
- Not automatically. Diameter, width and tolerances must match both the bearing and the shaft. Check the dimensions against the assembly data sheet, and if you are unsure, send us the details and we will help you confirm.
- How should an LR inner ring be mounted?
- Fit it onto the shaft with the correct interference, keeping impacts away from the raceway. Confirm alignment with the bearing and apply lubrication as required. Follow the manufacturer's mounting instructions, or contact our team for guidance.
