Thin Section Bearings

Thin-section bearings are characterized by their thin rings and small cross-sections. They are lightweight, offer low friction, and provide high rigidity and precision.

Key Features:
  • Particularly useful for compact, lightweight configurations with higher bore diameters.
  • High rotation precision.
Applications:
  • Widely used in aerospace, medical devices, industrial robotics, textile printing, radar communication, astronomy instrumentation, and other high-precision industries.
