more stepper specs needed

Sorry guys,
Came across some interesting looking steppers, wanting some more info
on them.
Japan Servo
kp86sm2-002
nema 34 2.35v
3-3/4" long
I was wondering if anybody had the current ratings, and maybe how
powerful they are.
Searching for them only brought me to the place selling them.
Thanks in advance.
Regan
