Long Pitch 6L
Short Pitch 12 / 18 / 24
Base Material SS304 · SS316L · Duplex · Alloy steel
Surface Plating Hard chrome · Tungsten carbide
The hollow rotor is lighter, so starting torque and motor size shrink — saving electricity. Lower friction slows stator and rotor wear, high-speed start-stop vibration is minimal, and running noise drops, helping plants meet workshop noise standards. Pair with an equal-wall stator for the best combination.
