Abstract
A roller bearing seal includes an insert part and a polymer part connected to the insert part, and the insert part includes an annular-disc-shaped middle section having a radially inner deflection and a radially outer deflection, and a first ratio (L2/L1) of an axial length (L2) of the outer deflection to an axial length (L1) of the inner deflection is less than 0.65.
Claims17
A roller bearing seal comprising an insert part and a polymer part connected to the insert part, wherein the insert part comprises an annular-disc-shaped middle section having a radially inner deflection and a radially outer deflection, and wherein a first ratio (L2/L1) of an axial length (L2) of the outer deflection to an axial length (L1) of the inner deflection is less than 0.65.
A cylindrical or tapered roller bearing including a plurality of rolling elements disposed between an inner bearing ring and an outer bearing ring, wherein sections of a bearing cage are disposed between the rolling elements and a seal is disposed at at least one axial end of the roller bearing, and wherein an insert part is provided in the seal, and wherein the insert part includes a deflection and wherein a section of the bearing cage overlaps the deflection by at least 100% of a material thickness of the bearing cage.
