Beschreibung
Zusammenfassung:	The invention discloses a sealed cylindrical roller bearing for railways. The sealed cylindrical roller bearing comprises an inner ring, an outer ring, a roller, a first sealing cover and a second sealing cover, wherein the two axial ends of the inner ring are provided with edges, the outer ring is arranged outside of the inner rings, and an inner chamber is formed between the outer ring and the inner ring; the roller is positioned in the inner chamber, the roller and the outer ring can move together relative to the inner ring along the axial direction, and the first annular sealing cover is fixedly arranged on the outer ring; the second annular sealing cover is fixedly arranged on a flange, two axial sides of the inner chamber are sealed by virtue of the first sealing cover and the second sealing cover, and the outer ring moves relative to the inner ring along the axial direction; the first sealing cover and the second sealing cover always has an area and radial clearance along the radial direction. The sealed cylindrical roller bearing can be used for solving the problem that the sealing effect is poor when the displacement of the existing sealed cylindrical roller bearing for railways in the axial direction of the outer ring is relatively large.
