【Machine Tools】ESX20M-13 Series Rotary Joint for Coolant-Through
Rotary Joint
Features
- Mainly used for built-in spindles (other spindles are also available)
- Improved assembly ease to spindle (13060, 13061 series only)
- Highly durable mechanical seal made of special ceramic
- Internal seal structure for smooth stroke and sealing performance
- Rotation without fluid is possible

| ✔ | Over 10 L/min | 875 N | |
| Over 2.64 gal/min |
Notes
1. Rotation without fluid: Rotation of the rotary joint without fluid supply. (dry running)
2. Minimum seal operating flow rate: When the fluid is coolant.
3. Thrust loading to spindle side: When the fluid pressure is 7 MPa (proportional to fluid pressure).
