In graphite, each carbon atom is bonded to three other carbon atoms in the same plane giving a hexagonal array.
Graphite's structure is formed by the hexagonal arrays being placed in layers one above the other. Due to these layers, it has a slippery texture, and therefore it is used as a lubricant.

Graphite. Used in food industry, railway track joints, open gear, ball bearings, machine-shop works etc. It is also very common for lubricating locks, since a liquid lubricant allows particles to get stuck in the lock worsening the problem. Rest are hars.

In simple words it is because graphite is less bounded with the surface so it's used as a lubricant. For example in pencils for smooth writing.

Due to structure of graphite layer by layer and slippery in nature due its structure so it is used as lubricant.

It is able to offer lubrication at temperatures higher than liquid and oil-based lubricants can operate.

Because of weak chemical bonding, Graphite layers can sliding through each other on application of pressure. Thus it can be used as a lubricant.
