Linear Motion CNC Ball Screw Ball Screw C7 Set SFS2020 L1050-1400mm with Single Nut + BK15 BF15 Support Seat + DSG20H + Coupling Suitable for Engraving Machine(1300mm)

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: SFS2020Guide rail width or diameter: 20mmMaterial: S55CBall screw accuracy: C7Description:Ball screw accuracy: C7, C7 ball screw accuracy ensures accurate and reliable motion control of machine tools.Comprehensive package: includes ball screw, nut, bearing and coupling for immediate integration.Material: S55C, made of S55C steel, ensures durability and precision in application.Guide rail width: 20mm, 20mm guide rail width provides a balance of rigidity and flexibility for a variety of projects.Package includes:1 pcs SFS2020 ball screw with end machining, suitable for BK/BF151 pcs SFU2020 ball nut1 pcs BK15+BF151 pcs D30L40 8x12mm coupling1 pcs DSG20H nut housingNote: The above ball screw is the total length, including the machined part.

• 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. The guide rail is not easy to get stuck during linear motion
• 2. The slider slides smoothly and has high operating stability
• 3. The optical axis and the aluminum seat are fixed with high-strength screws, which are firm and firm
