Claims

[Claims for Utility Model Registration] (1) Cylindrical rollers are rotatably interposed between an outer ring and an inner ring, each having flanges on both ends in the axial direction,
In a cylindrical roller bearing in which a seal plate is attached to at least one shaft end, either the outer ring or the inner ring is a combination of a bearing ring with a single flange and a flange ring, or a single flangeless bearing ring. Shaft end of at least one of the collar of a bearing ring with a single flange and a collar ring combined with the bearing ring, or at least one of the collar ring combined with a bearing ring without a flange, which is constructed by a combination of a bearing ring and two flange rings. On the outer diameter surface or inner diameter surface of the side, there is a first
The seal plate is formed with an inclined surface or step surface of the step, and a step surface and a notch surface of the second step connected thereto, and is attached to the other of the outer ring and the inner ring. A core bar is formed with an annular part that extends in the radial direction and is connected to an inclined part that is bent to a radius. and a lip portion made of an elastic body extending in the direction or diagonal direction, the tip side surface of the lip portion of the seal plate slidingly contacting the inclined surface or stepped surface of the first stage with respect to either the outer ring or the inner ring, A sealed cylindrical roller bearing characterized in that an annular portion of a core metal is adjacent to a step surface of a second stage and a notch surface with a slight axial clearance and a slight radial clearance, respectively. (2) The sealed cylindrical roller bearing according to claim 1, wherein both sides of the attachment portion of the core metal of the seal plate are coated with an elastic body. (3) The sealed cylindrical roller bearing according to claim 1, wherein the inner surface and the tip surface of the tip of the annular portion of the core metal of the seal plate are coated with an elastic body.
