Structure and features
The balls run in four precision-ground raceways between a guide rail and a linear guide carriage, with end plates integrated into the linear guide carriage allowing the balls to circulate. Cage plates protect the balls from falling out of the linear guide carriage when it is pulled off the rail (except types HSR 8,10 and 12). Due to the arrangement of the rows of balls at a contact angle of 45°, the HSR compact guide has the same load ratings in the radial, counter-radial and tangential directions. In this way, the HSR can be used in different installation positions. In addition, the linear guide carriage can be preloaded, which increases the rigidity in the four directions. At the same time, a constant, low coefficient of friction is maintained with constant running characteristics. Due to the low overall height and the high rigidity of the linear guide carriage, this type achieves a highly precise and constant linear movement
Same load capacity in all cardinal directions
Due to the arrangement of the four rows of balls at a contact angle of 45°, the HSR type has the same load ratings in the radial,
counter-radial and tangential directions. In this way, the HSR can be installed in different installation positions and for a wide variety of applications
Applications are used
High rigidity type
Since the balls are arranged in four rows, a high preload can be applied and the rigidity can be easily increased in all loading directions
Self-adjustment skills
Due to the X arrangement of the four circular arc grooves with 2-point contact, the linear guide carriage can compensate for negative influences of assembly errors on running accuracy even under preload.
Long service life
Even with preload or high load, there is no differential slip of the balls. This achieves smooth movement, high wear resistance and long-term maintenance of accuracy.
