Profile Rail Assemblies are specifically designed with matching the runner block to the ground rail. This combinations provides unique benefits.

Smooth Operation at Both High and Low Speeds

  • Precision ground full radius ball tracks provide smooth ball circulation and reduced friction.
  • The unique ball recirculation design permits stable, high speed travel.


  • High quality materials are hardened by an advanced heat treatment system resulting in increased durability and performance.
  • Direct lubrication to ball grooves through a grease fitting insures adequate lubrication. The one-piece seal design retains lubricant and effectively protects against contamination.
  • Full radius ball raceways self-align to help absorb small mounting errors and distributes related stresses evenly.
  • The Nook Profile Rail design has been extensively tested to insure long reliable life.
