"球面支承" can be translated as "spherical support" or "spherical bearing" in English, depending on the specific context and technical usage.
"Spherical support" generally refers to a structure or component that provides support in a spherical or omnidirectional manner.
"Spherical bearing" is more commonly used in mechanical engineering contexts to describe a type of bearing that allows for rotational movement in multiple directions, often with a spherical contact surface.
In most technical or engineering contexts, "spherical bearing" would likely be the more appropriate term for "球面支承".
