- **Caution**: 

### Q: What materials are carriage blocks typically made from?
**A**: Carriage blocks are commonly manufactured from carbon steel for general applications or stainless steel for corrosion resistance in harsh environments.

### Q: How does a carriage block function in a linear guide system?
**A**: The carriage block houses rolling elements (like balls) and moves precisely along the rail, providing smooth linear motion with minimal friction in machinery applications.

### Q: What are the key components of a carriage block assembly?
**A**: A complete carriage block assembly typically includes the main block body, end seals to prevent contamination, ball retainers to maintain element spacing, and mounting holes for secure installation.

## 6. Manufacturing Compliance
- ISO 286-1:2010 (LIMITS AND FITS FOR CYLINDRICAL PARTS)
