GooEquip Linear Guide HGR15 1500mm Linear Rail with 4PCS Slider Block + 1PCS SFU1605 1500mm Ball Screw with Ball Nut, BF12/BK12 Support, DSG16H, Coupling for 3D Printer CNC Machine.

"HIGH EFFICIENCY and HIGH QUALITY: The ball screw uses a ball movement, so that the torque is low at start-up and no creep movements occur, ensuring precise positioning. No stick-slip effect, less heating, lower drive power required high static and dynamic stiffness. "PREMIUM LINEAR GUIDE SYSTEM: The motor-driven guide rail achieves highly precise linear motion. Designed for high-precision linear movements with low friction coefficient. "EASY INSTALLATION: Steel linear guide rail with pre-drilled holes for easy assembly. Stainless steel linear rail for linear motion. Easy to install, maintenance-free. "HIGH-QUALITY STEEL MATERIAL: The linear bearing is made of high-quality bearing steel. A beautiful and rust-free surface treatment ensures durability, high hardness and stiffness. Smooth operation, low noise and environmentally friendly. "WIDE APPLICATION: Grinding machines, milling machines, lathes, drilling machines and comprehensive processing machines, discharge manufacturing machine, drilling machine, line cutting machine, precision measuring instrument, woodworking machine, loader and shipping machine."
