MISUMI Linear Guides Calculator
Linear Guide Selection Tool
Load from CG point
CG Distance from reference point (mm)
X = Along travel direction | Y = Lateral offset | Z = Height above carriage surface
Linear Guide Mounting Orientation
Rail/Block Configuration
More blocks/rails = more stable, better moment capacity · 2 rails / 4 blocks recommended for general use
Top view: RS = distance between the two rails • BS1 = distance between two blocks on the same rail (measured along travel) • RS/BS1 are the same for all mounting orientations
Enter real spans for accurate per-block load: P = F/n + (moment ÷ span) vs C₀ • leave blank = previous approximation
Safety Factor (SF)
➕ Additional External Force (optional)
Enter "0" to calculate based on the payload only.
Recommended Product Code Based on Selection
These are general reference values (N·m) for various Rail Widths — verify actual values from the MISUMI Catalog before final selection.
| Model (Rail Width) | MA (N·m) | MB (N·m) | MC (N·m) | C dyn (N) | C0 static (N) |
|---|---|---|---|---|---|
🔗 Use calculated MA, MB, MC × Safety Factor values and compare against Allowable Moments in the MISUMI Linear Guide Selection tool (configurator.misumi-ec.com) to confirm the appropriate model.
