Linear Motion CNC Ball Screw T8 Lead Screw Set Lead 4mm Pitch 2mm with Nut KP08 Vertical Bearing 5 * 8mm Flexible Coupling for DIY 3D Printer Parts(550mm)

1. End processing ball screw, minimum starting torque, easy to use. Compact design for easy installation and removal.2. Ball screw is made of high quality and durable steel, wear-resistant and high temperature resistant. It provides spiral raceways for ball bearings and as a precision lead screw plays an important role in situations where high precision is required.3. Small sliding friction: The sliding friction of CNC parts between nuts and screws is small, so the service life is longer.Specifications:Model: T8 trapezoidal lead screwScrew diameter: 8mmDescription:Made of high-quality stainless steel, smooth movement It has low friction, which helps the nut move smoothly on the screw. It also helps the screw to work precisely and accurately. It has a certain load-bearing capacity and can be fixed on ordinary precision racks. It has strong adaptability and can be widely used in 3D printers, stepper motors, 3D engraving machines and other DIY kits.Packing list:1pcs T8 trapezoidal lead screw1pcs nut1pcs coupling D25L19 5*8mm2pcs KP08 pillow bearing seat
