The standard linear bearings that come with the Tronxy X5S printer are made of plastic. After my first boast in bed, it was all over. I found them and tried 2 of them. WOW. They are very strong and provide much needed Z-direction dimensional stability. Please note they are not sold in pairs. They are expensive but made of very high quality steel.
