HRNSG518R08 - Aluminum 5mm to 1/8 inch Pinion Reducer Sleeve

This product is an aluminum reducer sleeve that transitions a 5 mm shaft to a 1/8 inch bore, allowing smaller motor pinions or accessories to fit larger 1/8 inch components. Machined from lightweight aluminum, it provides precise concentricity to maintain smooth rotation and reduce vibration. The internal and external diameters are engineered for a snug fit with minimal slop, helping preserve drivetrain efficiency. Its anodized finish resists wear and corrosion during repeated use.
