A recirculating ball is a type of steering mechanism commonly used in vehicles. It consists of a gear mechanism that converts the rotational motion of the steering wheel into linear motion, allowing the wheels to turn. This system uses a series of ball bearings that circulate within a channel, reducing friction and providing smooth steering. The design of the recirculating ball system offers several advantages, including durability and the ability to handle heavy loads. It is often found in larger vehicles, such as trucks and SUVs, where robust steering performance is essential. This mechanism is distinct from other steering systems, such as rack and pinion.
