🔧 Key specifications (SJ-V22-06ZT)
| Parameter | Value |
|---|---|
| Series | SJ-V |
| Short-time rated output | 22 kW |
| Motor type | Medium-inertia AC spindle motor |
| Design focus | Heavy cutting / stable torque machining |
| Bearing type | High-speed spindle bearings |
| Shaft configuration | Through-spindle (T type) |
| Cooling | Machine/forced-air dependent |
| Application class | Large CNC machining centers |
⚙️ What “06ZT” means
- 06 → design / winding variant within the 22 kW SJ-V class
- Z → revised / optimized internal design version
- T → through-spindle (hollow shaft) configuration for coolant/tool-through machining
So:
06ZT = 22 kW SJ-V spindle motor with through-spindle capability and a specific design revision
🏭 Typical applications
SJ-V22-06ZT is used in:
- CNC vertical machining centers (heavy duty)
- large milling machines
- industrial production lines
- high-torque metal cutting operations
It is chosen when machines need:
- very high cutting force at low/medium speed
- stable continuous spindle load capability
- rigid, vibration-resistant machining performance
⚖️ Position in Mitsubishi spindle lineup
| Series | Role |
|---|---|
| SJ-DL | Ultra high-speed drilling/tapping |
| SJ-DJ | Compact lightweight spindles |
| SJ-V | General-purpose + heavy machining spindles |
| SJ-DG | High dynamic / high-performance cutting |
🧠 Simple explanation
SJ-V22-06ZT is a 22 kW-class CNC spindle motor designed for heavy machining centers, optimized for strong torque and stable cutting rather than high-speed operation.
