- **Caution**: 

### Q: What materials are available for high-precision linear motion ball bushings?
**A**: Our linear motion ball bushings are manufactured in Chrome Steel (GCR15) for high durability, Stainless Steel (440C) for corrosion resistance, and Engineering Plastics (POM) for lightweight applications.

### Q: What are the key specifications to consider when selecting a linear ball bushing?
**A**: Critical specifications include bore diameter, outer diameter, length, dynamic load rating (in Newtons), static load rating, and operating temperature range to ensure compatibility with your machinery requirements.

### Q: How does the ball bushing design contribute to smooth linear motion?
**A**: The precision ball bearings within the retainer and outer sleeve assembly provide minimal rolling resistance, while seals/shields protect against contamination, ensuring consistent low-friction movement in industrial applications.
