deep groove ball bearing 608
608 is a kind of miniature bearing, the 6 in 608 bearings represent the 6 series deep groove ball bearing, 0 is the size series, and 8 is the size of the inner diameter is 8mm. The dimensions are 22mm outer diameter, 7mm height, and 8mm inner diameter. There are 7 steel balls with a diameter of 3.969mm. 608 bearing with dustproof cover and seal cover, with dustproof cover in the model suffix ZZ (608ZZ), rubber cover in the model suffix 2RS(608-2RS). Material has carbon steel, bearing steel (GCr15), stainless steel, plastic, ceramic, and so on. Cage: nylon cage, iron cage, copper cage, and so on. Can be used for: a single reduction machine, plastic welding machine, lace machine, sliding guide rail, flotation equipment, automatic sandblasting machine, indentation machine, rubber cutting machine, dropping pill machine, weaving machine, drainage and irrigation machinery, reaction kettle, concrete mixer, ironing equipment, washing machines, automatic pump, bottle blowing machine, steel rolling equipment, radial drilling machine, and so on. Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing and can bear the combined diameter and axial load. When the speed is higher and it is not suitable to use thrust ball bearings, it can also be used to bear pure axial load. Compared with other types of bearings of the same size as deep groove ball bearings, the friction coefficient of this kind of bearing is small and the limit speed is high. But not impact-resistant, and not suitable for heavy loads.
