Description
1. Self-aligning Capability: Features front-mounted X-type (45°×45°) arc raceway groove design with automatic alignment compensation. The internal mechanism absorbs minor mounting surface deviations to maintain high-precision, smooth, and stable linear motion.
2. High Rigidity Four-Directional Equal Load Design: Incorporates 4-row ball circuits with 45° contact angle configuration, achieving optimal two-point contact for bidirectional radial/lateral load capacity. Optional preload application enhances system rigidity when required.
3. Interchangeability: Stringent manufacturing precision ensures dimensional consistency within stable tolerances. Integrated retainer design prevents ball dislodgement, enabling between and matching guideways while preserving operational smoothness, preload integrity, and motion accuracy.

High-rigidity linear guide system optimized for precision positioning in industrial automation. Features corrosion-resistant treatment and enhanced dustproof capability through multi-stage sealing. The H-grade preload ensures minimal deflection during high-moment applications.

Typical Applications:
  • CNC router Z-axis positioning systems
  • Semiconductor wafer handling robots
  • Automated optical inspection (AOI) equipment
  • High-speed packaging machinery
  • Medical imaging device sliding mechanisms
Installation note: Use torque-controlled tightening (2.5-3.0Nm for M6 screws) and laser alignment for parallel rails. Apply thread locker on mounting screws. Relubrication interval: 1,000km travel or 6 months in normal conditions.
