Cross Roller and Ball Rails

Cross Roller / Cross Ball Rail

Comprised of two pieces of stainless steel rails with V-shaped grooves which been hardened and ground forming precise rolling elements. Cross roller rail moves with alternate 90 degrees rollers to accomplish high parallelism and high flatness. In construction, rolling elements are transmitted in cross-contact by precise roller and V-shaped grooves in rails, and in non-circulation. Part numbers include two sets of rails.

Material Specifications:

Rail: SUS330C + Ni
Roller: 100Cr6
Retainer: Sus304

ADVANTAGES
Suited for micro-movement applications due to small amount of frictional resistance, with almost no difference between starting friction resistance and dynamic friction resistance. Stability in low speed applications: Even in the case of light loading, low to high speed variations are stable due to the low
amount of frictional resistance.

  • High rigidity - high loading capacity applications: Compared between roller or ball rails. Roller rails have a higher capacity due to their larger contact area, less elasticity deformation, and non-circulation, and great effective number of units in contact.
  • Low noise: Nook linear motion cross roller rail has no circulated rotating, no noise occurred. Using roller with roller retainer makes no noise caused by contact friction in between each rolling unit moves alternately, to ensure a quiet movement motion.
