Bearing the gap at home and abroad

Bearing gap at home and abroad source: bearing | last updated: - 2020 06 - 30 bearing gap at home and abroad imports bearing is mainly used for pure radial load, also can bear radial load and axial load at the same time. When it suffered only pure radial load, the contact Angle is zero. Bearing radial clearance is big, has the performance of angular contact bearings, can withstand a larger axial load. Bearings with low friction coefficient and high limit speed, especially under the condition of the axial load of high speed running, Sex is superior to the thrust ball bearings. Has been reported to bearing is the most representative of rolling bearing. On the structure, bearing every ring has a continuous groove raceway, the cross section of about a third of the ball equatorial circumference of a circle. Bearing is mainly used to bear radial load, also can absorb a certain amount of axial load. When bearing radial clearance increases, it has characteristic of angular contact ball bearing, and can withstand the variations of axial load in both directions. Compared with other same size bearing, this kind of bearing small friction coefficient, extreme high speed, high precision. When the user selects, it is the preferred type of bearing. Bearing has simple structure, easy to use. It is a kind of imported bearing, has the largest production and the most extensive application scope. Bearing can be divided into: ( 1) Miniature bearing - - - - Nominal diameter of 26 mm below the bearing; （ 2) Small bearings, 28 - nominal diameter 55mm； （ 3) Small and medium-sized bearings - - - - Range of 60 - nominal diameter 115 mm bearing; （ 4) Medium and large bearing - - - - Nominal diameter range is 120 - The 190 mm bearing ( 5) Large bearing, nominal diameter range is 200 - 430毫米; （ 6) Oversize bearings - - - - Range of nominal diameter is 440 mm or larger bearings. Bearing can be used for transmission, instrument, motor, household electrical appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo-yo, etc.
