Excelente!

Guys, I'm really well pleased with your service delivery. I doubted, and took a chance, but you surely out performed my worries. Thank you very much

Measures just under 21 all down shaft (centre section is same diameter). Liberally Coated in machine oil. Internally consists of two sets of bearing each with 4 races (8 in total). Each race has 7 balls visible.

It works fine, very smooth and precise. It will be cool if the length would be 60 mm ( the dubble of 2 single bearings).

Excelente, tudo como descrito. Obrigado Banggood
