Ultra-compact linear motion solution combining ball screw and guide rail in one integrated structure. Features zero-backlash ball recirculation system with 4-row angular contact design for high rigidity. The "AH" suffix indicates special precision grinding with ≤±0.005mm/m positioning repeatability. Includes pre-lubricated bearings and corrosion-resistant treatment for maintenance-free operation.
- Precision optical lens positioning systems
- Semiconductor wafer handling robots
- 3D printer Z-axis drive mechanisms
- Medical analyzer probe arms
- Laboratory syringe pump linear drives
Installation tip:
Use 0.02mm/m grade straightedge to verify rail parallelism during mounting.
Apply M4×8mm flat-head screws at 15N·m torque with Loctite 243 threadlocker.
Avoid exposing to cutting fluids - requires additional wiper seals if used in CNC environments.
