More Information:
Deep groove ball bearings are probably the most popular and widely used type if bearing in the world. This 2Z type bearing is manufactured with metal shields, pre-packed with grease lubricant. The shielded type deep groove ball bearings are generally used in applications where they can be introduced to dust or dirt such as pallet truck wheels, conveyors and skateboards. Unlike the 2RS sealed bearings, the metal shield doesn’t make contact with the inner ring, therefore the starting and running toque value isn’t affected. This deep groove ball bearing 6212-2Z SKF has an inside diameter of 60 mm, an outside diameter of 110 mm, and a width of 22 mm.
