Why are recirculating steel balls used in most conventional steering gears?

Recirculating steel balls are utilized in most conventional steering gears primarily because they significantly reduce friction within the steering mechanism. This reduction in friction enhances the ease of steering and allows for smoother operation. When the steel balls recirculate through the steering gear, they create a rolling contact that effectively minimizes the sliding surfaces, leading to less wear and improved longevity of the components.

This design feature allows for a more precise and responsive steering feel, which is critical for vehicle control and driver comfort. By lowering the amount of resistance that the driver has to overcome while steering, recirculating steel balls help maintain consistent performance and reliability in the steering system.
