Linear Motion CNC Ball Screw 1pcs T20 Lead 4mm Trapezoidal Screw Nut Length 100-900mm 3D Printer Stepper Motor Machines Parts(350mm)

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.Packing Included:1pcs : T20 screw with copper round nutDescription:Packing Included: T20 screwNut: CopperScrew: stainless steelDiameter: 20mmLead: 4mm(The distance the nut moves in one turn)Pitch: 4mmPurpose: 3D printer Z axis drive, linear motion, small confidential instrument

• 1. The transmission system runs more accurately, more firmly, with less noise and longer life.
• 2. Made of high-quality carbon steel, smooth and beautiful surface, low friction coefficient, no stick-slip effect, less heat, required drive power reduction, high transmission efficiency.
• 3. Ball screw is widely used in CNC milling machines, lathes, machine tools and other automation machinery.
