We never stop upgrading our beloved Lenco. This time is the BEARING.
Our Bearing upgrade kits including:
1. One 5mm tungsten Carbide bearing.
2. One 1.2mm T x 12mm Dia. 999 Pure Silver Plate.
Lenco originally using a 5mm stainless steel bearing. If you disassemble the whole spindle housing, which is pretty mush easy, you will find the spindle sits on the SS bearing and the bearing sit on a 0.75mm thick (sort of) PVC skeet (which we believe is for anti-resonance purpose) and then sit on a (1.5mm) metal plate hold by a circlip. Also, we always find this skeet in badly deformed condition (pls. see photo 5), which definitely not considering good in operation when the stainless steel bearing is turning on top of it (>_<'). We have tried quite a few market available upgrade options, which, to some extend, did improve or change the sonic result. Personally, I believe thia all depend on your personal tastes. So if you are considering an upgrade here, please do consider our option too.
In the following video, we demo the sonic different between the original SS bearing and our upgrade kits, a Tungsten Bearing and an extra 1.2mm thick PURE 999 silver plate, which need to put in between the bearing and the original holding steel plate. (For best performance, we strongly suggest you to stick the silver plate onto the steel plate with 3M self-adhesive tape.)
