A single replacement ZR02 Full Ceramic line roller bearing which replaces the standard part on a number of Shimano reel models. Unlike stainless steel bearings full ceramics do not corrode and are quiet (when lubricated) and long lasting. They are oiled with light oil and will still need occasional cleaning and re-oiling to keep them free of grit and dirt.
Bearing Size: 5x8x2.5mm
SINGLE BEARING -replaces Shimano Part No BNT2143 and BNT2948.
