Deep groove ball bearing features

Row deep groove ball bearing characteristics of single row deep groove ball bearing is most widely used of all ball bearing type, because it USES a variety of sealing ring, dust cover and stop ring device. Bearing ring raceway is made slightly larger than the sphere of the circular arc. Ball and raceway form point contact ( Have a load for the elliptical contact) 。 Deep groove ball bearings mainly take radial luck, also can withstand a certain amount of axial load. This kind of bearing size range and diverse forms. Friction torque is small, the most suitable for requirements at high speed, low noise, low vibration. Such as precision instruments, low noise motors, automobiles, motorcycles and general machinery, is the most widely used type of bearings in machinery industry. Bearing according to their diameter size is divided into: 1. Miniature bearing: D 26 mm or less; 2. Small bearings: 28 mm D 55 mm or less or less; 3. Small and medium-sized bearings: 60 mm D 115 mm or less or less; 4. Large bearing: 120 mm or less D 190 mm or less; 5. Large bearing: 200 mm or less D 430 mm or less; 6. Oversize bearings: D> 430mm。 Maintains a generally made from stamping steel, nylon cage has been widely used. With sealing ring or dust cover deep groove ball bearings have been standardized. They are stored in advance the right amount of grease. Bearing main use: car: rear wheel, transmission, electrical equipment parts. Electrical: universal motor, household electrical appliances. Other: instrument, the material machines, construction machinery, railway vehicle, loading and unloading handling machinery, agricultural machinery, all kinds of industrial machinery.
