System for collecting information
First Claim
1. A method for monitoring the condition of bearings in a gyratory crusher and for decreasing damages caused by a worn bearing, characterized in that friction forces between bearing surfaces in a crusher is monitored by sensors, and that information gained from the monitoring of the friction force carried out by the sensors is used in an alerting or control system of the crusher.

Abstract
Malfunctions of sliding bearings of gyratory crushers used in crushing stone are anticipated by providing sensors in connection to bearing parts, by means of which sensors it is possible to observe increases in friction forces. A beginning bearing damage can be detected by means of sensors at such an early stage, that extensive damage to bearings and to other parts of the crusher can be prevented.
