Spot the difference.!!! . . . . Can You see know how I didn't spot It was 10mm pitch straight away.!! . . .The nut length gave it away.
3 circuits (rows) 6 plugs. 3 circuits is a typical for 16mm dia, 4X usually on 20mm and above.!
As you can see quite a bit longer body and obviously ever so slightly more resistance due to extra set of balls.


No didn't get any Datasheet, I didn't even know he was sending me twin start so didn't ask. I will email him to see if he as any specs.

Will be a couple of weeks before I have them on the machines and working so will let you know how they perform.?????
