MOTION & CONTROL High-Accuracy Series Suitable for equipment ranging from machine tools to high-precision instruments—high-performance linear guides with premier motion accuracy Patent Pending

Realizing outstanding motion accuracy with high rigidity and load capacity—High-Accuracy Series high-performance linear guides, HA Type and HS Type Trends toward higher performance and enhanced quality of electronics equipment and precision instruments have been accelerating. At the same time, demand has been growing for highly precise production systems that manufacture such equipment and instruments. NSK strives to always stay ahead of competition by providing the industry with products that keep pace with trends and needs of the times. Part of these products are the high-performance linear...

High-Accuracy Series Test results of ball passage vibration High rigidity and high load capacity with low friction Ball passage vibration can translate into posture changes in the ball slide which result from ball passage (circulation). In the High-Accuracy Series, this vibration has been substantially reduced to one-third of conventional models. Substantially increasing the number of balls in both HA Type and HS Type achieves higher rigidity and load capacity as well as reduced frictional resistance, compared to our conventional models. HA Type 380 nt poi ent m ure 460 eas M HS Type For example,...
