ROLLER BEARING SEAL, ROLLER BEARING UNIT, HEAT-RESISTANT POLYMER CASING FOR ROLLER BEARING SEAL AND METHOD FOR ASSEMBLY OF ROLLER BEARING SEAL Russian patent published in 2021 - IPC F16C19/22 F16C19/38 F16C33/78 B61F15/22 

FIELD: bearing.

SUBSTANCE: invention relates to a roller bearing seal. A roller bearing seal comprises a seal body (320), an elastomeric rim (322) attached to the inner diameter edge of the seal body (320) for sealing between the seal body (320) and the wear ring (120) with simultaneous rotation of the seal body (320) and the elastomeric rim (322) around the wear ring (120), and a polymer casing (310) partially wrapped around the non-supporting side of the seal body (320) and covering the seal. The polymer casing (310) includes an inner diameter mount (312) surrounding the rotational axis (190) of the roller bearing seal. The inner diameter mount (312) is configured to attach the polymer casing (310) to the outward-facing surface of the wear ring (120) so that the inner diameter mount (312) forms an acute angle with the outward-facing surface along the entire circumference of the outward-facing surface. Also proposed are a roller bearing assembly, a heat-resistant polymer casing for the roller bearing seal and a method of assembly of the roller bearing seal.

EFFECT: creation of a roller bearing seal for holding the lubricant inside the bearing and preventing intake of water, dirt and other contaminants to the bearing.
