What are INA Linear Guide Rail & Carriage Assemblies?

INA, a brand of Schaeffler, offers linear guidance systems (monorail guidance) consisting of:

  • Guideway / Rail: A hardened, profiled steel bar that provides the tracks or raceways.
  • Carriage / Block / Slider: This component rides on the rail and includes rolling elements (balls or rollers), seals, wipers, etc.

These assemblies enable linear motion with precision, stiffness, load capacity, and, in many cases, support long travels.

INA Linear Guide Rail & Carriage Assemblies FAQs

What’s the difference between ball and roller carriages?

  • Ball guides (KUVE, KUSE, KWVE, etc.): Lower friction, higher speed, smooth running, but lower stiffness vs. rollers.

  • Roller guides (RUE series): Higher rigidity, better for heavy loads and moments, but generally slower than ball systems.

How do I choose the right guide size?

Consider:

  • Load capacity (static/dynamic).

  • Moments (torque loads) if the carriage is offset.

  • Rigidity/stiffness requirements.

  • Speed and acceleration requirements.

  • Space/installation dimensions.

Can multiple carriages run on one rail?

Yes. Often multiple carriages are mounted on the same rail to increase load capacity or to stabilize a moving platform.
