FAQ (Frequently Asked Questions)

Q: What does “G2” mean in this module?
A: G2 is a precision grade indicating tighter tolerances and improved smoothness of the linear motion.

Q: What is the significance of “C” and “W1” in KUME15-C-W1?
A: “C” denotes the compact version of the carriage, while “W1” is a specific carriage configuration or wheel variant within the series.

Q: Is this module pre-lubricated? Can it be relubricated?
A: Yes, it is factory-lubricated. In many applications, you can apply additional lubricant for extended service life.

Q: What guide shaft size should be used with KUME15?
A: Use Ø15 mm precision shafts with tight tolerances (e.g. h6/h7) for best geometry and performance.

Q: Where is this product commonly used?
A: In miniature CNC axes, optical systems, precision automations, micro-robotics, and instrumentation when compact linear motion is required.
