6303ZZ 6303-2Z Deep groove Ball Bearing 17x47x14mm Industrial Bearing Manufacturer

Description An Over view of Deep groove ball bearing The bearings are the most typical rolling bearings with extensive applications. The raceways in both of the rings are in arc groove form, which can carry radial and axial load in double directions. They can be applied in situations where high-rotating speed and low noise and low vibration are required.  Bearing structure  Deep groove ball bearing has simple structure, compared with other types of easy to achieve high manufacturing accuracy, so easy to become series mass production, lower manufacturing costs, the use of very common. Deep groove ball bearing except basic types, there are various kinds of structural change, such as: deep groove ball bearings with dust cover, deep groove ball bearings with a rubber sealing ring, deep groove ball bearings with snap groove, deep groove ball bearings have high load capacity of ball filling gap, double deep groove ball bearings.  Types Basic type; With snap ring groove on the outer ring (-N); With one shield (-Z) on one side or two shields (-2Z) on both sides; With one seal (-RS) on one side or two seals (-2RS) on both sides.  Application The bearings can be found in  transmission, instrumentation, motors, household appliances automobiles, machine tools, motors, instruments, construction machines, railway vehicles, agricultural machines and various other special machines.   Deep groove ball bearing is the most common type of rolling bearing. The basic deep groove ball bearing consists of an outer ring, an inner circle, a set of steel balls and a set of maintenance frames. Deep groove ball bearing type has a single row and double row two kinds, deep groove ball structure is sealed and open two kinds of structure, open without sealing structure refers to the bearing, seal type deep groove ball into dust seal and oil seal. The dust – proof sealing material is a sheet metal stamping, which simply prevents the dust from entering the bearing roller. The oil-proof type is the contact oil seal, which can effectively prevent the grease spillover inside the bearing.
