Bearings - 1/4" x (12) x 2mm

These were purchased for my AD20. Can't say I was not happy with mechanics on oem Demko bearings, they are also ceramic. But I simy can't trust enough that hollow ball cage. Solid brass cage is better in all aspect + 3 more balls is always for good. Now Demko revealed it's whole potentia! Recomended for Demko knives!

I was wrong!

I didn't really think these would make very much difference in a new AD20 (full MG). I was wrong. Even smoother and much less of that Demko mechanical steel sound. I use EWG grease instead of oil and the results with the Skiffs are fantastic!

Easy install and great upgrade for my ZT-0393.

Easy install, bearings are well made and noticeably made a big difference in action and blade stability compared to the factory KVT bearings. Great precision product.
