Deep groove ball bearings, the bearing of the most representative structure, use common. Located in the inner ring, outer ring raceway on, was slightly larger than the radius of the arc radius of the ball rolling cross-section. 

 In addition to competing in line to bear, but also can accept axial loads in both directions. Mount Qi torque is small, the combined requirements for high-speed reverse, low noise, low vibration use. 

 This bearing, except way, there and plate bearing dust cover, rubber sealed bearings plus, perhaps on the outer ring with snap ring bearing. 

 Adhere to common use more steel stamping frame. Combined with the insistence of the first frame: steel stamping insist frame (waveform, crown-shaped ... separate; S-shaped double row ...); copper alloy or phenolic resin cutting adhere to frame to form a resin molding adhere frame. 

 Primary use: car: rear, transmission, electrical installation components; Electrical: General Electrical idea, household appliances. 

 Other: instrumentation, internal combustion engines, construction machinery, rail vehicles, material handling machinery, agricultural machinery, all kinds of mechanical property
