NSK HA Series High-accuracy Linear Guides (high-precision machines)

NSK HA Series High-accuracy Linear Guides (high-precision machines)

NSK HA Series high-accuracy linear guides use long ball slides to minimise waving and give high rigidity for high-precision machines and measuring equipment. Sizes 25 to 55.

Key features

  • Long ball slide with many balls for very small waving motion
  • High accuracy and rigidity for precision machines and measuring equipment
  • Ultra-precision P3 to high-precision P5 grades
  • Flanged and square ball slide types
  • NSK K1 lubrication unit available
