CNC Stepper Motor Source

[OiUkes]

Looking for a source for Chinese 6040 X & Axis Stepper Motors. Froze after a year, under "warranty" but no help from seller.
NEMA 23 frame size 57mm x 76mm, 3A, 200 steps 1.8 degrees, 8 mm main shaft with a 6.35mm rear shaft for handwheel. Any info including correct Nm (oz-in) holding torque appreciated.

Been looking for an hour.
Haven't found anything below 114mm length with 2 different shaft sizes.
It's either change coupling or change handwheel.
All I found so far:
