Block entities store additional information about certain blocks, with the type of information varying by block. In some cases, this information is used to create a more complex model, such as the book on an enchanting table. In other cases, it is used to store contents of an object. Blocks with block entities can be moved by pistons.[Bedrock Edition only]

Block entities and their render limits[Java Edition only]
Some block entities, or their effects, stop being rendered beyond a hard-coded block limit which is modeled after the radius of a sphere. This limit is not affected by Render Distance nor the Entity Distance scale in the Video Settings.
