Worked great on HICTOP DC-11 printer

These bearings are a one for one replacement for the HICTOP printer linear motion bearings. Worked great on HICTOP DC-11 printer.

Exactly as advertised

Straight, accurate and works. Worth the price.

Fixed my Y-axis problem..

My 3d printer had bronze bushing instead of linear bearings and my print quality suffered. These bearings are very smooth and my prints immediately improved. Worth every penny.

Five Stars

fitment is good, quality material used.

good for the price

Building a little project and I needed to make a sliding platform. Think these will do just fine, it takes a 8mm or 5/16" rod and M4-0.7 screws, tapped about 1/4" or 6mm deep

Nice tight and smooth fit

Replaced my previous 1 year old sloppy bearings with these. Nice tight and smooth fit.

Just what I needed.

Replacement part for a 3-d printer kit.
