💡 Why are sealed deep groove bearings used in electric motors?
Sealed bearings like the 6306DU are great for electric motors because they keep grease in and contaminants out - reducing friction, wear, and the need for maintenance. They ensure longer service life, especially in dusty or damp environments.

Quiet, clean, and tough - drop the 6306DU into your motor or machine and keep it running smooth and sealed!
