Welcome to our store! Aluminum alloy spacers have many uses and can be used to bind loose ends of machine parts. Create spacing between parts, reduce hole size, add spacing for bolts, install bearings, or use as a lightweight shaft. Aluminum alloy spacers have an outer diameter of 6 mm, which is very suitable for creating space between two components on a 6 mm shaft or pillar. Allows 6 mm bearings to be mounted on gaskets, and the thick wall provides excellent strength. The surface of the aluminum alloy spacer is anodized, which is resistant to wear and corrosion.
