Ultra-compact linear guide optimized for precision motion in constrained spaces. Features hardened steel rails with corrosion-resistant treatment and aluminum carriages for optimal stiffness-to-weight ratio. The BP preload ensures minimal deflection during acceleration/deceleration cycles. Integrated dust-proof seals maintain lubrication integrity in ISO Class 4 environments.
- Medical device positioning stages (CT scanner arms, biopsy robots)
- Semiconductor wafer handling equipment
- High-speed PCB assembly machines
- Desktop CNC milling/drawing machines
- Automated optical inspection (AOI) systems
Installation protocol:
Mount on machined reference surface (Ra≤1.6μm). Use 0.02mm feeler gauge to verify parallel alignment between rails. Torque M3 screws to 1.2N·m in crisscross pattern. Run-in with 20% speed for first 50 cycles.
