Furthermore, the circular-arc groove provides a wide-contact width between the balls and the groove raceway allowing large permissible loads and high rigidity. And a retainer is added to prevent the balls from falling out when the blocks are removed from the rail.īecause of the four-row design, the HG series linear guideway has equal load ratings in the radial, reverse radial and lateral directions.
Self-aligning capability, high accuracy and smooth operation can be obtained with an easy installation.īecause of precision dimensional control,the dimensional tolerance of HG series can be kept in a reasonable range, which means that any blocks and any rails in a specific series can be used together while maintaining dimensional tolerance. HG series can absorb most installation errors due to surface irregularities and provide smooth linear motion through the elastic deformation of rolling elements and the shift of contact points. Thus, HIWIN HG series linear guideways can achieve a long life with high speed, high accuracy and smooth linear motion.īy design, the circular-arc groove has contact points at 45 degrees. HIWIN Corporation manufactures, services and repairs Motion Control products including: Linear Guideways, Ballscrews, Linear Motors, AC Servo Motors & Drives, Linear Actuators, Elevator Gearless Traction Machines, Crossed Roller Bearings, Positioning Measurement Systems, Single Axis Robots and Torque Motor Rotary Tables. It features equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation-error. HG series linear guideways are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization.
