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.
Category: Linear Guides | Brand: AIRTAC | Series: LSH
Installation tip:
Use 0.02mm/m grade straightedge during mounting. Tighten screws in
diagonal sequence at 30%→60%→100% torque stages (recommended torque: 8.8Nm).
