The differential divides the engine torque between two tires equally allowing one wheel to rotate faster than the other when a vehicle turns.

Spider gears are an essential component of a differential, mounted on its case. They ensure a smooth turn without affecting the movement of the whole off-highway vehicle. Furthermore the spider gears absorb all loads from the ring and pinion gears under changing speed and thus protect vehicle components from getting worn out.
