CG Series – Superior Rolling Moment with Cover Strip Linear Guideway

CG series linear guideways are a four-row arc-tooth contact type, featuring high rigidity, high load, and high torsional resistance. It also has four-way load characteristics. This specification can be matched with the latest slide dustproof accessories.

Features of CG Series

High Rolling Moment Resistance

CG rail designed with DB type (also known as o arrangement) has longer range of moment compared do DF type (also known as x arrangement). It is suitable for applications that have larger rolling moment.

Optimal Recirculation Path

Better smoothness due to integrated component.

Better Protection

The CG series uses a metal scraper as a standard accessory for protection against high temperature chips and particles.

Latest Dustproof Accessory for Rail

The CG series offers a special stainless cover strip for better dust protection than standard bolt caps.

Full Lubrication

Specially designed for short stroke motion (HIWIN patent design).

  • Machine Centers
  • NC Lathes
  • Grinding Machines
  • Precision Machining Machines
  • Heavy Cutting Machines
  • Automation Devices
  • Transportation Equipment
  • Measuring Equipment
