## Customer Reviews

### ⭐⭐⭐⭐⭐ Good hardened rod for linear motion applications
*by C***R on September 15, 2020*

I ordered the 20mm rod just under 1m in length. This is nice hard, chromed shafting. I mic'd it out and it was perfect, though I did not go crazy measuring the rods, they work very well with my LM20UU long bearings. I really like the cut to length option. The ends are not turned, but arrived nicely cut with what looks like a cooled (no heat discoloration) abbrasive saw. The ends are very nicely beveled and there are no burs or sharp edges on the rods. I added a picture of the ends as cut, as I was very happy with the quality of the cut to length servicePackaging and shipping were excellent and nicely protected the rods from the abusive handling packages seem to see in shipping.

### ⭐⭐⭐⭐⭐ Perfect replacement for worn shaft
*by S***S on January 23, 2024*

I needed to replace the bearing and axle shaft on an old bike trainer stand, and the original vendor has been out of business for 20 years. When I measured the old bearings and axle, they were stock metric sizes, and this rod matched up perfectly with new bearings. This is a quality product offered at an exceptionally good price.

### ⭐⭐⭐⭐⭐ Precise in length, and diameter. Solved my needs on a DIY CNC Machine.
*by T***S on October 9, 2020*

Both rods were straight, smooth, and precise in length. Being able to order a custom length saved me a lot of time. Most 12MM rods are of some standard lengths, and require cutting to fit the project. Great buy, and nearly the same price as standard length rods of the same (near same) length.
