Hardened version works great

Ordered the hardened option for high load application. It holds up well under stress. Diameter tolerance seems accurate when measured with calipers.

Excellent Precision for CNC

Used these shafts for a custom CNC router build. The straightness is impressive and the chrome plating is smooth. Linear bearings slide on perfectly without binding.

Good value for money

Surface is smooth and no rust upon arrival. Took a bit longer to ship than expected, but the quality matches the description. Would buy again.

Well protected packaging

Concerned about rust during shipping, but the oil and wrapping were sufficient. Shaft arrived in perfect condition. Very satisfied with the purchase.

Length slightly off

Quality of the steel is good, but the 1000mm shaft I received measured closer to 990mm. Not a dealbreaker for my project, but worth noting.
