Ultra-compact linear motion solution featuring optimized ball recirculation for smooth operation in constrained spaces. The hardened raceway and precision-ground surfaces ensure minimal friction fluctuation (±15% variation). Includes integrated oil retention felt pads for maintenance-free operation up to 1,000km travel under normal conditions.
- Medical device positioning stages
- Semiconductor wafer handling robots
- High-speed PCB drilling machines
- Precision optical alignment systems
- Desktop CNC engraving equipment
Installation guidance:
Requires mounting surface flatness ≤0.02mm/m. Use torque-controlled tightening
(1.2N·m max for M4 screws) in cross-sequence pattern. Avoid side-load applications
exceeding 30% of radial load capacity.
