1The bearing cover is a vital component that seals and protects the eccentric shaft bearings in C series jaw crushers. It is installed on the pitman assembly, with four covers per crusher – two on each side of the eccentric shaft. These covers prevent dust, dirt, and moisture from entering the bearing housing while keeping lubricant safely inside. A well‑designed bearing cover directly extends bearing life and reduces unplanned downtime. Weight varies depending on the crusher model; please refer to the specific model for exact data.
