What is the primary advantage of the 45° contact angle?

The 45° contact angle allows the trains of balls to bear an equal load in all four directions (radial, reversed radial, and lateral). This ensures the carriage remains rigid and stable regardless of how it is mounted on the machine.

Is the MSA 20S interchangeable with other MSA rails?

Yes, for the 'Interchangeable Type' of PMI guideways, the dimensional tolerances are strictly maintained, allowing for random matching of rails and carriages of the same size while maintaining similar accuracy and preload.

How should I maintain my PMI MSA 20S block?

Maintenance is simple via the integrated grease nipple. For standard industrial use, we recommend a high-quality lithium-based grease. Re-lubrication every 100km of travel or every 3-6 months is standard, depending on environmental debris.
