旋回リング用スチールボール Ø 6 mm、16個

I was a bit worried about the fit, but the 6 mm diameter is exactly what my slewing ring needed. The 16-piece set gave me enough spares for future maintenance, and the steel feels properly hardened.

Swapped out the old worn balls in my rotary table with these 6 mm replacements—the 16‑piece set was exactly enough. They roll smoothly and feel noticeably harder than the generic ones I tried before.

Exactly 6 mm diameter, so they fit my slewing ring without any play. The 16-piece set was enough for one full replacement, and the steel feels solid and well-machined.
