Reliable in Operation - Despite Contamination and High Shocks
This application places high demands on the bearing support. High bearing forces, extremely high speeds and an environment that is highly contaminated. INA has therefore developed a special bearing support for variable speed mechanisms.
It consists of a radial insert ball bearing with optimized load carrying capacity and a shock-resistant housing made of spheroidal graphite cast iron with centering spigot which enables it to be easily fitted on the frame of the combine harvester. The high speeds require concentric movement of the shaft, which is achieved by using an adapter sleeve. The flinger shields pressed onto the inner ring prevent the ingress of contamination into the bearing, which ensures the reliable operation of the variable speed mechanism.
