2Pcs 10mm x 300mm (0.394 x 11.81 inches) Vigorous Linear Motion Rods, Case Hardened Chrome Shaft Linear Rail Guide Shaft for 3D Printer, DIY, CNC - Metric h8 Tolerance

I built a 20" band saw and purchased 1" bearing and a 1" shaft. Even with freezing the shaft I couldn't get it onto the bearings. So, I purchased this. Since it isn't driving a gear, It's OK that the bearings fit a little loose (nothing a small shim made from a strip of aluminum from a pop couldn't fix). I used a grinder to cut this shaft into two 250mm lengths for the upper and lower bandsaw wheel shafts. The chrome is nice since there is 90% humidity where I live at times and I don't have to worry about it rusting.

High polish finish, perfect for what I needed them for; precise machining.

Wood sanding wheel, used this to hold the wheel. Added some ball bearings & hooked up to an old drill that only spins one way. Works great.

replacement for an old worn out 3D printer.

These rails are straight and smooth just what I needed.

They are exactly 10 mm in diameter. They are very round. They do not more or complain. What could possibly go wrong?

This bar is the right diameter to bend a cetme flat around and buying it though amazon was the cheapest option. It didn't flex in the press, just worked out great.

I measured these with my calipers and found them to be right on spec. They look clean and are straight from what I can see. I am not a machinist, just a hobbyist building things in my garage, so I am sure they'll be more than sufficient to my needs.

Thank you.
