Vexta Stepper motor Torque

Does any one know what the holding torque of an Oriental Motor Vexta PH268-21 is?

Or here if it is an older motor:

THANKS!!!

I spent about 2 hours searching and never came across that cross reference.

The cross reference is useful but the replacement PK series normally outperform the PH series. I have PH268-E2.3 and PK 268-2A. The PH are eight wire, and at 3.4 A in bipolar parallel really don't out performed the PK's at 2 A half winding. The PH 268-E2.3's have 135 OZin holding torque, and the PH268-2A's have 187 OZin. The flatter torque curve of the PH meant slightly faster rapids on my Lathe, but I swapped to the PK's.
