## Description

CNCMANS has been committed to providing superior 3D printers and accessories services.The linear track is uniformly stressed, sliding smoothly, made of carbon steel, corrosion-resistant,and high-temperature resistant.The linear bearing can travel infinitely together with the cylindrical shaft. Because of pointcontact between ball and straight axis, so the load is small. The ball is spinning with the smallestfriction, it can run a high precision and smooth motion.Flange linear bearings can be divided into:round flange type, oval flange, guide wheel flange, guide the oval flange type, plus long roundflange type.The shaft is case hardened. If you use normal steel shafts, the bearings will cut them up in notime. So make sure what you buy is case hardened!Specifications:Brand: CNCMANSModel: SBR20Shaft Diameter: 20mmSBR20 Linear Rail Kits Includes:2x SBR20-800mm Linear Slide Guide Rails4x SBR20UU Bearing BlocksFeatures:Steel material and hardened caseHigh accuracy and strong durabilitySmooth moving, low friction, high rigidity and long working lifeSuits X, Y, Z axis,perfect items for your CNC project

### ⭐⭐⭐⭐ Review
*by L***X on 28 July 2022*

Great rails but with just a little bit of flex. I used these for a router sled. There were two drawbacks. The first was hunting for the correct screw size of the holes on the mounting blocks. (Metric6 by the way) The second if a little bit of flex in the rails. For a full size router I may have to go back and add some steel underneath the rails so they don't sag.
