Professional HGR20 Linear Guide & Ball Screw Kit for CNC Automation
Upgrade your CNC machine or automation system with our industrial-grade HGR20 linear motion kit. This set is engineered for maximum rigidity, high precision, and long-term stability in demanding environments.
Superior Component Quality
The HGR20 rails provide a stable guiding surface, while the HGH20CA blocks utilize a four-row circular arc contact design to absorb even loads from all directions. Paired with the high-efficiency SFU1605 ball screw, you can achieve micron-level accuracy and zero backlash.
