6001 Deep groove ball bearing parameters, specifications, 6001 (12 * 28 * 8mm) Bearing Type: deep groove ball bearings domestic new models: 6001 Domestic older models: 101 inside diameter (mm): 12mm (0.4724in) outside diameter (mm): 28mm (1.1024in) Width (mm): 8mm (0.315in) Weight (KG): 0.022 basic static load rating (kN): 2.38 (242.86KG) basic dynamic load rating (kN): 5.10 (520.41KG) greased speed (r / min): 20000 oil lubrication speed (r / min): 26000 Features: 1, 2 high speed, high precision 3, noise and vibration 4, 5 main radial load, but also bear certain axial load 6 , create a simple, low cost Mainly used to maintain frame: steel stamping cage (waveform, crown-shaped ... separate; S-shaped double row ...) copper alloy or phenolic resin cutting cage, synthetic resin forming cage main purposes: Automotive: rear, transmission, electrical equipment electrical components: General Motors, other household appliances: when instruments, internal combustion engines, construction machinery, railway vehicles, handling machinery, agricultural machinery, industrial machinery deep groove ball bearings Note 1, the shaft and deep groove ball bearing housing tolerances choice and control: deep groove ball bearing deep groove ball bearing pressed into the post should be flexible rotation without blocking sensation. If significant rotation is not flexible, it means that the shaft size is too big, the tolerance to be reduced. Such as deep groove ball bearings pressed into the shaft turned by hand after a significant rustle sense, it may be too much tolerance of the shaft or shaft roundness is not good. So when good control shaft and deep groove ball bearings have good control room roundness tolerances, many domestic manufacturers only tolerance control, no control of roundness. 2, deep groove ball bearing assembly methods: Because deep groove ball bearings are precision products, such as improper assembly is likely to cause damage to the deep groove ball bearing channel, resulting in deep groove ball bearing damage. Deep groove ball bearings in the assembly should have a dedicated mold and can not beat, when pressed into the shaft force only a small circle, the circle can only force when pressing circle. Assembly requires the use of pneumatic or hydraulic pressure, when the press-fit upper and lower mold levels to remain outside the state, if inclined groove ball bearings can cause damage due to power channel, leaving the deep groove ball bearing guide ring. 3, the assembly to prevent foreign objects: iron deep groove ball bearings can easily be generated when balancing the rotor balancing equipment to do when entering the deep groove ball bearings inside, so it is best to do before loading the deep groove ball bearing balancing . Some manufacturers in order to facilitate assembly, the assembly in deep groove ball bearing interior coated with some oil or grease lubrication effect, but often difficult for the volume control operation is good, if the oil or grease in the deep groove ball bearing interior accumulates more when deep groove ball bearings rotate easily enter deep groove ball bearings inside along the axis. Deep groove ball bearing chamber is best not coated with oil or grease, such as non-coated control shall not have to deep groove ball bearings indoor accumulates.
