Well Gents (and Ladies),

I am so far behind where I should be on my project. LOL. So I need to buy my ballscrews still.

I have received quotes from a number of places. I’m looking at Chinese rolled C7 ballscrews.

I’m looking at a few companies right now, wondering if anyone has had any experience with them?

I would actually be buying the double nut screws from them. DFU 2510. They don’t have them listed in their store, but I contacted them for a quote, and they have them. I’m leaning towards these guys right now.

Lishui Yingte Bearing Co.

I would be buying the single nut 2520 ballscrews from them (Yes, it’s an uncommon size, ideally I would like 2515), but I did find a place with the 2520.

LISHUI YINGTE BEARING CO.,LTD

About $100 USD more expensive, but I’m wondering if the quality is better. Also, they do have the 2520, which is an odd size.

Also considering BST Automation and YU Guest Store for single nut 2510 ballscrews, and have send an additional enquiry to YU Guest Store about their double nut TBI 2510 ballscrews.

Any feedback, good or bad, on any of these suppliers would be appreciated. Also any personal experience on double vs single nut or any other supplier (rolled Chinese variety) is appreciated.

Also, does anyone have anything to say about TBI brand ballscrews?

I’m quite happy with the Bun Brand bearings and SYK mounts I purchased earlier. I just need the ballscrews / ballnuts / ballnut housings and couplers at this point.
