A carriage block is a precision component in linear motion systems that moves along guide rails to provide smooth, accurate linear motion with minimal friction.
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Lubrication | Grease or oil, with intervals of 1000-5000 km | |
| Load Capacity | Dynamic: 5-50 kN, Static: 10-100 kN | |
| Preload Level | Zero clearance (Z0), Light (C1), Medium (C2), Heavy (C3) | |
| Accuracy Grade | Normal (C), High (P), Precision (SP), Ultra-Precision (UP) | |
| Mounting Hole Pattern | Standardized (e.g., 4-8 holes per block) | |
| Operating Temperature | -10°C to +80°C |

A carriage block is a complete assembly that includes bearings, housing, and seals, designed to mount directly onto a guide rail. A linear bearing is typically a simpler component that requires separate housing and is used in shaft-based systems. Carriage blocks offer higher rigidity and load capacity for precision applications.
Consider load capacity (dynamic and static), accuracy grade (e.g., P or SP for high precision), preload level (e.g., C2 for reduced backlash), environmental conditions (e.g., corrosion resistance), and compatibility with your guide rail model. Consult manufacturer datasheets and application guidelines.
Regular lubrication with specified grease or oil (every 1000-5000 km of travel), inspection of seals for debris, and checking for abnormal noise or vibration. Avoid over-tightening mounting bolts to prevent deformation.
