Each Rubner tuning machine gear mechanism includes 4 ErlingKlinger Moldflon anti-friction bearings placed at critical friction points — 3 in the gearbox and 1 underneath the cog. In addition to providing you with a smoother tuning experience, these teflon disks reduce wear and significantly extend the lifetime of your Rubner tuners.
