Good quality but packaging needs improvement

The steel bars themselves are great hardness and finish. However, the packaging was a bit loose and one shaft had a minor scratch. Still usable though.

Perfect for my 3D printer upgrade

The shafts are straight and the chrome finish is smooth. They fit perfectly into my LM10UU bearings without any binding. Very satisfied with the quality for the price.

Slightly bent on one end

Overall good product but one of the five bars I ordered had a slight bend near the end. The rest were perfect. Customer service was helpful.

Hardness is as described

I tested the hardness with a file and it holds up well. These are genuine 45# steel bars. Great for linear actuator projects.

Smooth finish

Very smooth surface which reduces friction significantly. My linear motion setup runs much quieter now. Highly recommend.

5 FAQ

Q: Is this compatible with LM10UU linear bearings?

A: Yes, this 10 mm shaft is designed to be compatible with standard LM10UU linear ball bearings.

Q: Can I order custom lengths if I need 1.5 meters?

A: Standard listings go up to 1000 mm. For custom lengths like 1.5 meters, please contact our support team directly.

Q: Is the chrome plating rust resistant?

A: The chrome plating provides good corrosion resistance, but we recommend applying light oil for long-term storage or humid environments.

Q: What is the straightness tolerance exactly?

A: The straightness tolerance is guaranteed at 0.05 mm per 300 mm length, suitable for precision linear motion applications.

Q: Does the shaft come pre-oiled?

A: It comes with a light protective oil coating to prevent rust during shipping. You should apply your preferred lubricant before installation.
