Deep groove ball bearing structure category:
Deep groove ball bearing structure is simple. Compared to other types of bearing, it's easy to reach high precision when manufacturing . Therefore, it's easily to produce with a mass production, and lower manufacturing costs, the widely use. Deep groove ball bearings according to sizes can be divided into:
	(1) Miniature bearings ---- nominal diameter size less than 26mm;
	(2) Small bearings ---- nominal diameter size range of 28-55mm;
	(3) Small to medium sized bearing ---- nominal diameter size range of 60-115mm;
	(4) Large bearing ---- nominal diameter size range of 120-190mm;
	(5) Large bearing ---- nominal diameter size range of 200-430mm.
