The Perfect Oilless SGO
It refers to every mechanical part, regardless of its shape and material, that uses self-lubrication or rolling character (ball, roller) to deliver power to different kinds of motion such as rotation, reciprocation, thrust, and angular pitching motion.
Its speed and load resistance are the most excellent in general condition.
(Used in high speed applications through point-contact motion)
(Used in high load parts through line-contact motion.)
It directly operates with shaft or sliding surface without rolling character and it requires gap when working. It is more suitable than ball & roller bearing for coping with impact and vibration in small size and light weight.
