The deep groove ball bearing is the most widely used bearing type. Its main characteristic structure is the relative actuation position of the inner ring and the outer ring. Processing of arc-shaped grooves enables the steel ball to rotate stably in this processing track. Run, hence the name. From the early loose steel balls to the groove structure, until today it has evolved into deep groove ball bearings. It is a relatively mature and economical configuration method on all levels of technology. Of course, we also use this as a basis, according to different conditions or motion force modes, such as angular contact bearings. Double row bearings. Flat thrust bearings. Full ball bearings. Flange convex bearings. Ceramic balls Bearings. Needle roller bearings. End rod bearings. Self-lubricating bearings... etc.
