Linear Motion CNC Ball Screw Guides Kit BORRGTU HGR20 Linear Rails 2pcs HGR20 Square Guide+ 4pcs HGH20CA Sliders+ 1pcs SFU2005 Ball Screw(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.Specifications:Model: HGR20+SFU2005Guide rail width or diameter: 20mmHM15-57 material: cast aluminumHM15-57: NEMA23 motorC7: plain bearingPacking list:2pcs HGR20 linear guide + any length4pcs HGH20CA slider1pcs SFU2005 ball screw with ball nut and BKBF15 end processing + any length1pcs DSG20H nut housing1pcs HM15-57 (C7 aluminum)1pcs BF15 end support1pcs XB30*40-12*14mm coupling
