Ultra-compact linear motion solution featuring a space-saving 12mm rail width and dual carriage configuration. The hardened raceway (HRC58-62) ensures extended service life in high-cycle applications. Integrated dust-resistant seals maintain smooth operation in particulate environments. Requires parallelism within 0.02mm/m between mounting surfaces for optimal performance.
- Precision optical lens positioning systems
- Medical analyzer probe arms
- Semiconductor wafer inspection stages
- 3D printer X/Y axis guidance
- Laboratory automation sample handlers
- Robotic joint articulation mechanisms
Mounting protocol:
Use 0.02mm feeler gauge to verify flatness during installation.
Apply Loctite 243 to mounting screws and torque in cross pattern.
Avoid side-loading beyond 15% of static capacity.
