Conical crusher with sliding bearings between the outer surface of the eccentric device and the inner surface of a skirt extending downwards from the crusher head, and also roller bearings between the eccentric device and the middle shaft housing. Lubricating oil throughflow paths run through the middle shaft housing and radially outwards to an oil groove which completely surrounds the inner surface of the eccentric device and directs the lubricating oil into an oil space between the inner surface of the eccentric device and the outer face of the middle shaft housing and from the oil space into the roller bearing. A radial oil channel runs from the oil groove through the eccentric device to the surfaces of the sliding bearings and the opposing inner surface of the skirt, for the lubrication of both cooperating surfaces. The main thrust bearing has pillars with a smooth surface, which cooperates with a spherical sector having radial and self-intersecting circular lubricating oil grooves. The lubricating oil received from all the bearings flows directly through each of the bearings, without first flowing through another bearing. A counterweight is provided for the flywheel of the eccentric device. At least parts of the flywheel cylinder wall are tapered inward and upward, in order to induce a flow of lubricating oil against these walls.
