This describes a 1610 nut plus a good video for repacking;

yep cheers eddy, watched this and a similar one. I`ve no problem re packing it, its just at the last circuit there`s a big gap left, this nut hasn't been used yet and I needed to turn it around so I decided to strip it and on counting the balls thought 50 is a strange number so that's why I `m asking

well mine ended up with 51 total, 17 in each circuit.

I thinking that should be right and mine has one missing, it felt ok and still feels ok now I`ve turned it, it was just an observation as I noticed the wipers looked like they`ve been in and out before, I think I`ll have a root about at work tomorrow and see if I can find any.

linearmotionbearings2008 (Chai) is one of the most used Chinese suppliers for this forum I think. Quality seems consistent with the price but I have not used any other similar products for comparison.

Other used ebay sellers I've seen mentioned are; solar.jean , supermario-au
Strangely you sometimes have to log into ebay.com to see the listings.

@bmbaz, This grease is the right stuff at the right price, http://www.toolstation.com/shop/p89691 , unless you intend to use oil.

Thanks eddy,yes I use toolstation for a few things because of price and proximity.I can now confirm that a 1605 ball nut has 17 ball per circuit as does a 1610,no idea why mine had one missing,it happens.I think i'll be using Wurth lithiun grease as i've a big tub of it from when I use to work for them(a sample,honest)again thanks for all the info.just putting finishing touches to a siegsuper x2 with help from Clive on the electrics and hope to post report soon,its only taken 6months or so..as it does:-S
