The listing includes three sets of supported linear rails BK/BF12 (with locknuts and circlips), six supported linear rails SBR20-300/600/1000 mm rails (6 supported rails+12 SBR20UU bearing blocks), three pieces of ballscrews RM1605-350/650/1050 mm-C7 (3 screws + three ball nuts + three end-machinings), and three pieces of flexible couplings. Move without deflection, with little wear, and with little noise.

• Complete Linear Rail Kits: This set consists of supported linear rails SBR20-300/600/1000 mm rails, three sets of RM1605-350/650/1050 mm-C7 ball screws, three sets of BK/BF12, and three pieces of 6.35 mm*10 mm couplings.
• Linear guides are composed of high-grade steel, which is a premium material. A ball screw that is highly efficient and produces little heat can assure precise micro feed and increase stiffness.
  
• Premier Linear Guiding System: Complete sliding unit system that can be moved without deflection and has a high degree of accuracy. The screw shaft and nut move around like large balls a lot. As a result, a high degree of movement efficiency is achievable.
  
• Easy to Install: High-quality support rail with pre-drilled mounting holes. High-speed feed is achieved by the ball screw movement. It is easy to install and requires minimal work to maintain.
• Broad Uses: The linear guide rail is extensively used in CNC Router/CNC Grinding machines, industrial machinery for printing, paper-processing, automatic machines, X-Y tables, factory automation equipment, etc.
