The invention belongs to the technical field of coal mining equipment, and relates to a cage shoe roller with improved sealing performance. The cage shoe roller comprises a hub, a fixing shaft and a bearing. The hub and the fixing shaft form a rotation pair. A labyrinth gland and a sealing lip-wearing ring sealing device are arranged outside the bearing. The labyrinth gland is composed of a static seal ring and a movable seal ring. The static seal ring and the movable seal ring are provided with toothed seal ring bodies. The teeth are meshed to form a series of gaps and cavities. The sealing lip-wearing ring sealing device is composed of a seal lip, a wear-proof ring and a locating sleeve. The seal lip is an annular slice, the annular area, close to the circle center, of the annular slice is clamped by the static seal ring and the locating sleeve, and the edge of the annular slice is tightly attached to the sealing face of the wear-proof ring. The cage shoe roller is long in service life, convenient to lubricate, low in maintenance cost, and capable of improving production efficiency.
