8mm By 350mm Linear Motion Rod Shaft Guide Kit With 2 SC8UU Ball Bearings And 2 SK8 Aluminum Rail Supports Chrome Plated Rails For 3D Printers And CNC Machines
✔️ 8mm solid shaft, chrome finish, 2 SC8UU bearings, 2 SK8 blocks
This ready-to-install linear motion kit is ideal for upgrading or building precise motion paths in 3D printers, CNC routers, laser engravers, and similar hobbyist or professional machines. The solid shaft is 1045 steel with hard chrome plating for high strength, corrosion resistance, and low friction. The included SC8UU bearings ride smoothly on the chrome shaft, while SK8 blocks secure the shaft to the frame. Pre-drilled holes and the included M4 hex key simplify mounting and alignment for a clean, reliable setup.
