Roller screw support table, also known as ball screw support table, is a mechanical component used to support and guide a ball screw. It is typically used in precision machinery and automation systems to provide stable and accurate linear motion. The support table consists of a base, a guide rail, and a carriage that moves along the rail. The ball screw is attached to the carriage and the guide rail provides support and guidance to ensure smooth and precise movement. The support table may also include features such as seals, lubrication systems, and adjustable preload to optimize performance and extend the life of the ball screw.
