A large sealed self aligning roller bearing including a first race ring, a second race ring, rolling bodies arranged between the first race ring and the second race ring in one or more rows and a built-in sealing member. The sealing member includes an annular plate ring with a first periphery portion and a second periphery portion. The first ring includes a mounting groove for receiving the first periphery portion and the second race ring includes a sealing surface.

1. A roller bearing that is sealed, comprising, a first race ring,a second race ring,rolling bodies arranged between the first race ring and the second race ring, anda sealing member comprising an annular plate ring which when viewed in cross-section is formed by only three linear sections: a first linear section that forms a first periphery portion; a second linear section which forms a mid section having an annular land; and a third linear section which forms a second periphery portion, the first periphery portion being inclined relative to the annular land to form a first knee therebetween, the second periphery portion being inclined relative to the annular land to form a second knee therebetween, and wherein the first race ring includes a mounting groove for receiving the first periphery portion and the second race ring includes a sealing surface,wherein a first resilient member is attached to the first periphery portion for sealing the mounting groove and a second resilient member is attached to the second periphery portion for sealing abutment with the sealing surface on the second race ring, the first and second resilient members are separate and spaced apart, the second linear section being free of resilient material, the first resilient member being spaced from and outside of the first knee relative to the annular land, the second resilient member being spaced from and outside of the second knee relative to the annular land. 2. The roller bearing of claim 1, wherein the second resilient member includes a lip portion extending outwardly from the annular plate ring to be in abutment with the sealing surface and an attachment portion for attachment of the second separate resilient member to the second periphery portion, wherein a length of the lip portion and a length of the attachment portion are the same. 3. The roller bearing of claim 1, wherein the first resilient member is attached to a back side and a top of the first periphery portion, leaving a front side of the annular plate member free from any resilient material at the first periphery portion, and in that a locking ring is inserted into the mounting groove on an exterior side of the annular plate ring, wherein direct contact is allowed between the annular plate member and the locking ring. 4. The roller bearing of claim 3, wherein the first resilient member includes axially extending protrusions on a side facing from the annular plate ring, which protrusions engages with a side wall of the groove to allow a resilient mounting of the sealing member. 5. The roller bearing of claim 1, wherein the mounting groove is situated inside a side plane of the first race ring and arranged to taper at an angle relative to the side plane. 6. The roller bearing of claim 5, wherein the groove has an opening on the inner periphery of the first race ring which opening is situated outside a race track of the first race ring and a closed inner end which lies at a radial distance and axially inside the opening, and in that the inner end is situated axially inside an outer axial limit of the race track in the first race ring. 7. The roller bearing of claim 1, wherein the mid section is parallel with a side plane of at least one of the first race ring and a side plane of the second race ring. 8. The roller bearing of claim 7, wherein the mid section is flush with or lies at an axial distance less than twice the thickness of the annular plate ring inside the side plane of the first race ring and/or a side plane of the second race ring. 9. The roller bearing of claim 1, wherein the roller bearing is a spherical roller bearing. 10. The roller bearing of claim 1, wherein the roller bearing is a toriodal roller bearing.
