The GH series linear guides adopt a four-row arc groove design with a 45° contact angle, which enables equal load capacity in all four directions. They can be used in various installation methods such as X, Y, and Z axes. Not only do they have high load capacity and self-aligning function, but also their rigidity can be further enhanced by increasing the assembly preload. They are particularly suitable for products with high precision and high load requirements.

Features of GH Series
(1)Self-aligning capability
By design, the circular-arc groove has contact points at 45 degrees. GH 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.
(2)Interchangeability
Because of precision dimensional control, the dimensional tolerance of GH 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.
(3)High rigidity in all four directions
Because of the four-row design, the GH 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.
