Disadvantages Of Hydrostatic Bearing

advantages 1. high load carrying capacity even at low speeds. but in hydronamic bearing there should be adequate speed to carry the load by the lubricant. 2.,hydrostatic bearing with self-controlled ,although the hydrostatic bearing has advantages such as low friction and a high moving accuracy due to an averaging effect, it has disadvantages such as low
