Excellent precision for CNC

Used these for my router build. Straightness is impressive and the surface finish is very smooth. Highly recommend for precision projects.

Good steel, minor shipping damage

Quality is high but packaging could be better. One shaft had a small dent, but the rest were perfect. Material feels genuine.

Solid product

Good value for money, slight oil residue upon arrival but that is expected for rust protection. Works as intended.

Perfect fit for LM units

Slides smoothly with bronze bushings. The tolerance is tight enough for smooth motion without too much play.

Hardness verified

Tested hardness, matches specification perfectly. Great for linear bearing applications where wear resistance is key.

5 FAQ

Q: Are these compatible with LM8UU bearings?

A: Yes, 8mm shafts are compatible with standard LM8UU linear ball bearings.

Q: Can I cut this to custom length?

A: Yes, but re-hardening ends is recommended to maintain wear resistance at the cut site.

Q: What is the straightness tolerance?

A: Typically 0.05mm per 300mm length for standard precision ground shafts.

Q: Do you ship internationally?

A: Yes, we ship worldwide with tracking. Please check shipping rates at checkout.

Q: Is this material stainless steel?

A: No, this is high-carbon bearing steel designed for hardness and wear resistance, not corrosion resistance.
