There are significant differences between ZZ and 2RS in terms of bearing sealing methods.
ZZ represents bearings with double-sided dust covers, which are non-contact seals primarily used for dustproof sealing. The dust covers are stamped from steel sheets.
2RS, on the other hand, refers to bearings with double-sided rubber seals with a metal skeleton, which are contact seals. These seals rely on the elastic deformation of the rubber to secure tightly within the bearing, preventing grease leakage and the ingress of external contaminants.
There are also differences in material and installation methods between ZZ and 2RS.
The ZZ dust cover is stamped from molds and pressed into the bearing, classified as a non-contact seal.
The 2RS seal, being contact-based, relies on the elastic deformation of rubber to secure tightly.
In terms of application scenarios, ZZ and 2RS differ as well:
ZZ is primarily used in environments requiring dustproof sealing. It is suitable for situations with low sealing requirements and where the prevention of dust ingress is the main concern.
2RS is suitable for applications requiring higher sealing performance. It effectively prevents grease leakage and the ingress of external contaminants.
