SFC Linear Rail Slide Set, 2Pcs Hardened Linear Shaft + 4Pcs SC Bearing Blocks + 4Pcs SK Supports, Linear Motion Kit for CNC Router DIY MachineSFC Series Linear Shaft Guide Rail Set, 2Pcs Chrome Carbon Steel Linear Shaft + 4Pcs SC Box Linear Bearing Slides + 4Pcs Aluminum Alloy Shaft Supports, Precision Linear Motion Kit for CNC Router, Laser Engraver, 3D Printer & DIY Projects1. Premium Hardened & Wear-resistant MaterialThe linear shaft is made of high-carbon steel with hard chrome plating, reaching HRC62 hardness for excellent wear resistance and deformation resistance. The slide blocks and shaft supports adopt sturdy aluminum alloy, anti-corrosion and long service life, guarantee stable linear movement under working load.2. Smooth & Low-noise Linear MotionBuilt-in precision ball bearings inside the slide block deliver smooth, unobstructed sliding movement with low noise. The bearing block can lock tightly on the shaft to prevent falling off during operation, bringing stable and consistent linear transmission performance.3. Complete Kit & Simple InstallationPackage contains 2 linear shafts, 4 SC slide blocks and 4 aluminum shaft supports. Precisely machined mounting holes for easy assembly. Just align the block with the shaft end, push forward and fully insert to finish installation, saving your setup time.4. Wide Compatibility & Multiple Sizes AvailableAvailable in SFC12 / SFC16 / SFC20 with various optional lengths. Widely used for CNC machines, laser engravers, 3D printers, DIY router/lathe/mill sled, trainer rocker plate, automation equipment and other mechanical modification projects.5. High Load Capacity & Great StabilityThe supported shaft design effectively reduces shaft sagging over long span. It can handle both dynamic and static loads steadily, ideal for DIY machinery building and small automated equipment linear motion systems.
