Block entity

A block entity (also known as tile entity) is extra data associated with a block, beyond the finite set of block states associated with each block.

Usage
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 in Bedrock Edition, but not in Java Edition.

Block entities and their render limits
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 the Render Distance nor the Entity Distance scale in the Video Settings.

Block entities that stop rendering beyond 64 blocks include:
 * s

 * es
