SFU1605 kit: 1 x SFU1605 L250mm-1500mm play ball screw + 1 x BK12 support base + 1 x BF12 support base + 1x D25L30 6.35 x 10mm coupling kit + 1x DSG16H support housing + 2 x SBR20 linear rail fully supported + 4 x SBR20UU -Block Feature: With corrosion-resistant, high strength, wear resistance and so on. Easy to install, no maintenance required. Suitable for X, Y and Z axes Very high load capacity. Smooth and extremely quiet bearings for rails. Low friction loss, high transmission efficiency No stick-slip effect, heats up less, reduced drive power required. Minimum starting torque, high speed and micro-feed. Specification: Ball screw: Ball screws are used in airplanes and missiles to move control surfaces, especially when flying electrically by wire, and in the power steering of motor vehicles to convert rotary movements from an electric motor into axial movements of the rack. They are also used in machine tools, robots, and precision assembly equipment. High-precision ball screws are used in steppers for semiconductor manufacturing. Manufacturing process: Rolled thread Precision: class C7 Material: carbon steel Model: SFU1605 Diameter: 16mm Ball screw length (approx.): 250mm / 300mm / 350mm / 400mm / 450mm / 500mm / 550mm / 600mm / 650mm / 800mm / 850mm / 1000mm / 1050mm / 1200mm / 1500mm Linear rail: The linear rail is an inexpensive production of a linear motion system for unlimited stroke in connection with the cylinder axis. Because of the point contact between the ball and the straight axis, the load is therefore low. The ball rotates with the least amount of friction, it can perform a highly precise and smooth movement. Suitable for installation on all types of machines; such as: engraving machine, woodworking machines, printing machines, machinery, etc. Model: SBR20 Silver Diameter: 20mm Length: 300mm / 400mm / 500mm / 600mm / 1000mm / 1200mm / 1500mm Applications: ① For various types of vending machines and equipments ② Helps to build an economical linear guide system ③ Can be used for large transmission devices such as cylinder guides, which are composed of a main rail and an aluminum support to stabilize the original rail ④ Sliding blocks used in conjunction with rails slide smoothly through internal linear bearings ⑤ Industrial robots, cracker machines, ultrasonic cleaning equipment, solar energy support equipment and clothing, etc. Package Included: 2 pieces SBR20 linear rail + 1 piece SFU1605 ball screw （with machined end） + 1 set BK / BF12 + 4 pieces SBR20UU + 1 piece 1605 ball nut housing + 1 piece D25L30 coupling Note: Please allow slight errors due to manual measurement.
