Hardened properly
Performed a file test and the steel is definitely hardened as advertised. Great wear resistance for high friction applications.

Great for linear guides
Used these for a 3D printer upgrade. The fit on the shaft is smooth with no binding. Hardness seems consistent across all pieces in the set.

Precise fit
No play on the shaft. These sleeves are exactly what I needed for my machinery repair project. Highly recommend for precision work.

Good quality
Slightly oily upon arrival but that is expected for rust protection. Cleaned them up and they work perfectly. Good value for the price.
Q: Are these sold individually or in a set?
A: They are sold as a full set of inner rings. Please check the package contents attribute for the specific quantity included.
Q: Is this material stainless steel?
A: No, this is high carbon chromium bearing steel designed for hardness and wear resistance, not corrosion resistance like stainless.
Q: Can I return if I order the wrong size?
A: Please check specs before ordering. Returns are accepted for unused items in original packaging within the policy period.
Q: Do you offer a 15mm inner diameter size?
A: Currently, we only stock the 10mm and 12mm sizes listed in this product description. Please check our store for other sizes.
Q: What is the maximum load capacity?
A: Load capacity depends on the specific application and shaft alignment. Please consult engineering specifications for your machinery.
