Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a roller bearing assembly. Background Technology

[0002] Roller bearings are important mechanical parts, mainly used to support rotating mechanical bodies, reduce the coefficient of friction during movement, and ensure rotational accuracy.

[0003] For example, the authorized announcement number "CN214456087U" is named "Waterproof Component and Waterproof Structure for Escalator Roller Bearings". By installing mutually cooperating waterproof inner and outer covers, the annular retaining strip on the waterproof outer cover and the annular retaining groove on the roller core cooperate to form a sealing structure. The elastic lip on the waterproof inner cover abuts against the waterproof outer cover to form a sealing structure, which effectively improves the sealing effect on the side of the roller bearing, preventing external water from entering and providing a good waterproof effect.

[0004] The above-mentioned and existing technologies have the following drawbacks: the waterproof inner cover and waterproof outer cover of the bearing assembly need to be installed in conjunction with the ladder shaft, which requires high installation precision and is inconvenient for maintenance. In addition, the bearing assemblies on the market generally do not have waterproof function, so a bearing assembly with waterproof function needs to be designed. Utility Model Content
