CNCMANS SBR20-600mm Linear Rail Linear Rails and Bearings Kit 2Pcs SBR20 600mm Long Fully Supported Shaft Guide with 4Pcs SBR20UU Linear Bearing Slide Block Linear Guide for CNC Equipments

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 SBR20-600mm 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
