Spinergy R8 ceramic hybrid wheelchair bearings
Spinergy lists three R8 bearings for its 1/2 in axle wheels, and this ceramic hybrid is the highest priced of them. It is a deep-groove ball bearing with a 1/2 in bore and a 28.6 mm outer diameter. The maker sells it per pair, so a full set for two wheels needs two pairs. Blue-seal and metric red-seal R8 bearings are listed alongside it.
