⚙️ What “09T” means

09 → high-torque winding / performance variant within the SJ-V22 family
T → through-spindle (hollow shaft) configuration for coolant/tool-through machining

So:

09T = high-torque SJ-V22 spindle motor with through-spindle capability

🏭 Typical applications

SJ-V22-09T is used in:

heavy-duty CNC machining centers
industrial milling machines
roughing and high material-removal machining
production machining lines

It is selected when machines need:

⚖️ very strong low-speed cutting torque
🔩 stable heavy-load cutting
🧱 rigid spindle behavior during aggressive machining

⚖️ Position in Mitsubishi spindle lineup

Series	Role
SJ-V	General-purpose & heavy machining spindles
SJ-VL	Low-inertia tapping/drilling
SJ-DG	High dynamic/high torque cutting
