Technical Specifications and Recommendations for EX 28 Series CNC Slide Units

1. Product Overview:
The document details specifications for the EX 28 series CNC slide units, designed with ball screw and ball bearing ways. These units are suitable for precise linear motion applications in CNC machinery.

2. Size Variants and Dimensions:
Three size variants are specified: EX28.100, EX28.200, and EX28.300. Key dimensional parameters (in mm) for each size include:
- EX28.100: A=415, B=482, D=495, E=120, F=70, G=6
- EX28.200: A=515, B=582, D=495, E=120, F=50, G=8
- EX28.300: A=690, B=757, D=670, E=120, F=35, G=10

3. Performance Parameters:
- Stroke length: 20 mm x 5 mm (common across sizes)
- Maximum feed force (Vorschubkraft): 7000 N for all sizes
- Weight: Not explicitly stated per size but implied to vary with size

4. Mechanical Features:
- Ball screw type: Kugelumlaufspindel (ball circulating spindle)
- Linear guides: Roller circulating rails/pads (Führungen mit Kugelumlaufwagen)

5. Motor Preparation Options:
- In-line feed motor preparation (Vorbereitung Direktantrieb)
- Offset motor preparation for belt drive (Vorbereitung Riemenantrieb)

6. Recommended Applications:
These units are recommended for CNC slide units requiring high precision and rigidity, particularly where ball screw and ball bearing linear guides are preferred.

7. Additional Notes:
The document includes various numeric codes and dimensions (e.g., Ø20 x 5 mm, M6 screws) indicating mounting and assembly details, which are critical for integration but require further context for full interpretation.

This summary captures the essential technical data and recommendations for the EX 28 series CNC slide units, focusing on size, mechanical features, performance, and motor integration options.
