Profile Rail Systems and Runner Blocks

The compact design of Nook runner blocks offers greater design flexibility and several methods of mounting compared to other linear guidance systems. Special retainers and recirculation tubes prevent balls from escaping when the runner block is removed from the rail. (remove slowly with no-load)

Features And Benefits:

Equal load carrying capacity in four directions

  • Steel bearing balls recirculate between the rail and the runner block and contact both surfaces at a 45&deg angle. Equal load can be applied bi-directionally in both horizontal and vertical axes. Nook Profile Rail Systems are also capable of withstanding moment loads.

High Rigidity and High Moment Rigidity

  • Full radius ball raceways circular shape provides ideal ball to ball raceway contact giving greater system rigidity.
  • Precise geometry of ball raceway square configuration is ideal for preloading and provides high system rigidity.
  • A range of preloads are available depending upon the requirements for rigidity and load capacity. Preload is achieved by the selection of precisely graded ball diameter.

Automation Series

Suitable for most linear motion application where high cyclical cycles are not required.

The Caged Ball Chain Design provides lower friction and lower noise than traditional profile rail block designs. The benefit of a caged ball design prevents the bearings from incidental contact, which reduces friction, wear and noise.

Wide

The wide miniature linear guide series has the same benefits as the standard miniature rail with the addition of a wider rail and block. This allows for a larger moment load and capacity for the same size rail.
