Overview
NSK PER122 is a triple lip bearing seal manufactured by NSK, a global leader in bearing technology. This sealed bearing component is engineered to keep water, dust, and contaminants out of bearing cavities, extending bearing life and reducing maintenance intervals in harsh industrial environments. The triple-lip design offers superior protection compared to single or dual-seal configurations.
