MSA A/LA

Note: Request for size 55 and 65 MSA-A / MSA-LA carriage, please refer to MSA-E / MSA-LE carriage type.
Note: The basic dynamic load rating C of ball type is based on the 50 km for nomonal life.
　　　The conversion between C for 50 km and C₁₀₀ for 100 km is C=1.26 x C₁₀₀.
Note*: Single: Single carriage/ Double: Double carriages closely contacting with each other.

Unit:mm
