Linear Motion CNC Ball Screw Ball Screw Kit Dia 25mm SFU2505 C7 200-1000mm with Single Nut +BKBF20+DSG25H+17 * 14mm Coupler for 3D Printer(650mm)

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: SFU2505Guide rail width or diameter: 25mmBall screw accuracy: C7Ball screw pitch: 5mmNut: single nutSupport bearing: BK20 BF20Nut housing: DSG25HCoupling: D40L66--17*14mmPacking list:1 x ball screw with end processed according to the drawing1 x SFU2505 single nut1 x nut housing DSG25H1 x BK201 x BF201 x D40L66 coupler (inner hole 17mm*14mm)

• 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.
• 1. Large lead and high-speed movement, reducing movement time, more durable and stable
• 2. Waist-shaped nut, metal reverser, adjustable preload
• 3. Ultra-quiet, high wear resistance, high precision and high hardness
• 4. Smooth and non-stuck, long service life
