Several types of bearings are used in modern internal gear hubs.
FAG deep groove ball bearings are important components of internal gear hubs. In order to meet customer requirements, a bearing with reduced axial and radial internal clearance was developed that is extremely robust.
The sealing, noise characteristics and rating life have also been matched to customer requirements.
INA needle roller and cage assemblies reduce the friction between the planet wheel and the planet shaft. The needle roller and cage assemblies ensure that gearshift is smooth and reliable even under heavy loads and at high speeds.
INA sealing rings seal the components of the cycle gearshifter against contaminants and spray water.
The sealing rings selected, on the one hand, give very good sealing even against the loss of lubricant (=> smooth running, longer life) and, on the other hand, protect the cycle gearshifter against wear by ensuring low friction.
