Hiwin Ball & Race Systems

Hiwin linear guideways are designed with load capacity and rigidity higher than other similar products with circular-arc groove and structure optimization. It features equal load ratings in the radial, reverse radial and lateral directions, and self-aligning to absorb installation error. Thus, HIWIN linear guideways can achieve a long life with high speed, high accuracy and smooth linear motion.

HG Series Heavy Load Ball Type Linear Guideway

Features include:

Self-aligning capability

By design, the circular-arc groove has contact points at 45 degrees. 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. Self-aligning capability, high accuracy and smooth operation can be obtained with an easy installation.

Interchangeability

Because 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. And a retainer is added to prevent the balls from falling out when the blocks are removed from the rail.

High rigidity in all four directions

Because of the four-row design, the HG series linear guideway has equal load ratings in the radial, reverse radial and lateral directions. Furthermore, the circular-arc groove provides a wide-contact width between the balls and the groove raceway allowing large permissible loads and high rigidity.

EG Series Low Profile Ball Type Linear Guideway

Features include:

EG series linear guideway is possessed with high load capacity and high rigidity because of the four rows design.

It also features the same load in four directions and self-aligning capability to absorb installation error which can achieve high accuracy. Besides, the lower assembly height and the shorter length make the EG series more suitable for high-speed automatic machines and applications where space limit is considered.
