A device for aligning the refining disc of a refining apparatus, in which refining apparatus lignocellulose-containing material is disintegrated and refined, which device is intended to be arranged in a support (701) for the axle package of the refining apparatus, the supporting (701) resting on a ground surface, which axle package comprises the rotary refining disc of the refining apparatus, a rotation axle to which the rotary refining disc is attached, and a bearing housing (702) in which the axle is journalled by means of bearings arranged in the bearing housing (704). The device comprises a first wedge-shaped member (703), which is slidable in a direction along said ground surface, and a second wedge-shaped member (704) provided between the first member (703) and the bearing housing (702) of the axle package, which second member (704) is slidable in a direction transverse to the sliding direction of the first member (703), and the first member (703) when displaced in its sliding direction is arrange to displace the second member (704). The device comprises a control device for displacing the first member (703) and a support means (706), on which the bearing housing (702) rests, which is provided between the second member (704) and the bearing housing (702) and arranged to engage with a to the support means (706) complementary recess (707) of the bearing housing (702). The support means (706) has a convex contact surface (708) against the recess (707) of the bearing housing (702), and the convex contact surface (708) of the support means (706) is displaceable in relation to the surface of the complementary recess (707) of the bearing housing (702). Support and refining apparatus comprising said device.
