HSR - Four Way Equal Load

For Heavy and Ultra-Heavy Loads

The HSR's four trains of balls are arranged so that the contact angle is 45°, allowing each train to bear an equal rated load in all four directions, ie. radial, reverse-radial and both lateral directions.  The HSR can therefore be used in any installation direction.  Moreover, HSR enables the application of a well balanced preload, making it possible to increase rigidity in the four directions while maintaining a low friction coefficient.  The low-profile design and use of high-rigidity LM blocks provide stable, highly accurate linear motion.
