Ultra-compact linear motion solution combining high rigidity with minimal space requirements. Features preloaded ball recirculation for near-zero backlash operation (2μm repeatability). The corrosion-resistant anodized carriage integrates oil-impregnated retainers for maintenance-free operation in clean environments.
- Precision medical devices (DNA sequencers, microplate handlers)
- Semiconductor wafer inspection stages
- 3D printer Z-axis assemblies
- Laboratory automation: pipette arms, microscope slides
- Compact robotics (6-axis arm wrist joints)
- Optical alignment systems requiring micron-level stability
Installation Protocol:
Mount on machined reference surface (Ra≤1.6μm). Use 4.8-grade M3 screws torqued to 1.2N·m in cross pattern.
Avoid side-loading during assembly - max 0.05mm misalignment permissible. For full lifespan (50km travel),
relubricate annually with ISO VG10-15 grease.
