Are the ballscrew end bearings any good? The cheap ones I've seen, admittedly >2 years ago, all seemed to be quite poorly made as they exhibited end float, unless you fiddle about adding shims or better bearings. Have they improved?

Jonathan the ones I've been getting from Fred are excellent far far superior to those things from Chai in every way. Finish quality and operation, they don't need a thing doing to them. They come sealed in Bags and lubed up inside a box and are light years better.!
