Load Rating Definitions
- C₀ = Static load capacity
- C₁₀₀ = Dynamic load capacity - 100km travel life
- M₀Q / MQ = Cross moment
- M₀L / ML = Longitudinal moment
Order Code Examples
Rail Order Code
BM S 45-N-G1-KC-R1-500-52-52
- BM S 45 = MONORAIL Ball Profile Rail Size 45
- N = Standard (top mounting)
- G1 = Very accurate
- KC = Standard straightness
- R1 = Reference at bottom
- 500 = Rail length 500mm
- 52-52 = First/last hole positions
Carriage Order Code
BM W 45-A-V1-S11-LV-CN
- BM W 45 = MONORAIL Ball Profile Carriage Size 45
- A = Standard carriage
- V1 = Low preload
- S11 = Lubrication port position (top center)
- LV = Full greasing
- CN = No coating (not chrome-plated; hard chromium is CH)
