3 * RM1610 ballscrews, 780mm & 660mm

Has Chai given you any load ratings or datasheet for these twin start screws? Would be interesting to see how they compare to the single start. Do the ball-nuts have two or four rows of balls and are they the same dimensions as the single start nuts?

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.?????
