Perfect for custom linkage
These sleeves fit perfectly into my machined parts. The 304 steel quality is evident and there were no burrs on the edges.

Good but tight tolerance
The quality is great, but the fit was very tight. I had to use a reamer to get the shaft to slide in smoothly.
5 FAQ
Q: Can I cut these to a custom length?
A: Yes, 304 stainless steel can be cut using a hacksaw or tube cutter. Please deburr the edges after cutting.
Q: Do you offer bulk discounts for large orders?
A: Yes, please contact our sales department directly for pricing on orders exceeding 100 packs.
Q: What is the maximum load capacity?
A: Load capacity depends on the specific diameter and wall thickness. Please consult our engineering chart for precise load ratings.
