Precision Linear Guide Rail Set, 2x HGR20-1000mm Rails, RM1605 Ballscrew, 4 Blocks & End Supports for CNC Machines

Achieve smooth, accurate movement in your CNC projects with this HGR20-1000mm linear rail kit. The set includes 2 hardened steel guide rails, 4 bearing blocks, an RM1605-1000mm balls crew, BF12/BK12 end supports, and a plum coupling—everything needed for DIY CNC routers, lathes, and milling machines.

Premium Materials for Long-Lasting Performance:

• Linear rails made from hardened carbon steel (HRC62 hardness) for superior durability

• Bearing blocks constructed with GCr15 bearing steel for smooth operation

• Chrome-plated surfaces resist corrosion while maintaining precision tolerances

Engineered for Ultra-Smooth Motion:

• Precision-ground rails ensure low-friction linear movement (±0.01mm accuracy)

• RM1605 ballscrew delivers high torque transmission with minimal backlash

• Pre-drilled mounting holes simplify installation on CNC frames, 3D printers, and automation equipment

Versatile Applications:

Perfect for upgrading:

• DIY CNC routers & milling machines

• Precision lathes & 3D printers

• Laser cutters & automated manufacturing systems

• Industrial automation & measuring equipment
