The seals (ZZ) on both sides keep out dirt, eliminating the need for relubrication. Due to its miniature design, the bearing can only handle moderate loads and is therefore not designed for heavily loaded main axles or large models.\u003c\/p\u003e \u003cp\u003eApplications in model-building electromechanics include gear shafts and propeller drives, while applications in robot chassis include wheel or turntable bearings, as well as LED spotlight frames and small slewing-ring applications.
