HGR20 Linear Guide Kit with 2x600mm Rails and Ball Screw

The HGR20 linear guide kit is the ideal technical solution for those seeking precision and stability in linear motion. This set includes two 600 mm rails and a ball screw, ensuring smooth and quiet sliding. Thanks to its robust construction, the system maintains repeatability over time, even under intensive daily use, making it essential for projects requiring millimetre-level accuracy and low friction.

Main Features

• High durability: made of medium carbon steel with hardness HRC58–62 for enhanced wear resistance.
• Anti-corrosion protection: galvanized coating of at least 10 μm prevents rust in humid environments.
• Smooth movement: sliding blocks with ball bearings reduce noise and friction.
• Dimensional accuracy: surface finish between 0.1–0.22 μm and straightness of 5 mΩ/100 mm.
• High load components: includes BK12/BF12 end supports and a coupling designed for heavy loads.

Usage and Assembly

Installation is facilitated by pre-drilled holes in the sliding blocks, ensuring precise repetitive positioning even over long travel distances. The system combines the linear rails with the ball screw and corrosion-resistant nut housing, creating a stable motion axis. It is recommended to ensure strict alignment of the BK12/BF12 supports to maximise bearing lifespan.

Ideal For

This linear guide system is suitable for assembling 3D printers, milling machines, cutting machines, and various industrial equipment. It is the right choice for those needing high-precision linear rails and guides that eliminate deviations during CNC machine or automation device operation.
