Ultra-compact linear guide system optimized for precision motion in constrained spaces. Features chrome-plated rails with hardened tracks (HRC58-62) and preloaded stainless steel balls for smooth operation with 0.003mm-0.01mm preload options. The asymmetric ball groove design reduces torque variation during movement, while the triple sealing system extends maintenance intervals in contaminated environments.
- Medical device positioning stages (CT scanner components, surgical robots)
- Semiconductor wafer handling equipment
- High-speed 3D printer X/Y axis systems
- Precision optical alignment mechanisms
- Laboratory automation sample handlers
- Miniature CNC engraving machines
Installation note:
Use 0.02mm/m grade straightedge for rail alignment. Apply lithium soap-based grease
(ISO VG10-32) during assembly. Avoid cantilever loads exceeding 15% of static capacity.
