Great corrosion resistance

Used these in a humid environment for a marine application. No signs of rust after several weeks of exposure.

Excellent value

Much cheaper than local hardware stores for stainless steel spacers. Will definitely order again for future builds.

Perfect for my CNC project

These bushings fit exactly as specified. The 304 steel quality is evident and the polish is smooth. No burrs on the edges.

Good quality, tight fit

The material is solid, but the tolerance is very tight. Make sure your shafts are within spec or you might need to ream them.

5 FAQ

Q: What is the load bearing capacity?

A: Load capacity depends on the wall thickness and specific diameter selected. Please consult engineering tables for specific load limits.

Q: Can I cut these to a custom length?

A: Yes, you can cut them with a hacksaw or tube cutter, but please deburr the edges afterwards for safety.

Q: Do these come with threads inside?

A: No, these are plain sleeves and threadless spacers. They are designed to slide over bolts or shafts.

Q: Are these bushings magnetic?

A: 304 stainless steel is generally non-magnetic, though slight magnetism may occur due to cold working during manufacturing.

Q: How are these packaged for shipping?

A: They are wrapped in protective foam and placed in a sturdy box to prevent bending or damage during transit.
