Key Considerations for Miniature Linear Guide Selection
⚖️
1. Load and Service Life (Primary Indicators)
- Rated load: Check both dynamic load rating C (moving condition) and static load rating C₀ (stationary / impact condition). Actual load P ≤ 0.5C (safety factor ≥ 2).
- Moment load: Radial, lateral, and overturning moments (M1/M2/M3). Use dual rails + multiple blocks if necessary to improve torsional rigidity.
- Life calculation: Ball guide life formula: L = (C/P)³ × 50 km. Reducing load significantly extends service life.
