Airtac LSH Linear Guide Rail LSH25BK-F1N-P-E-M6
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.

Installation guidelines:
Requires surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use 68# guideway oil or ISO VG32 equivalent. Tighten M6 screws to 4.4-5.4N·m
torque in crisscross pattern. Avoid welding sparks near rail surfaces.
