High speed angular contact ball bearing(718C)  

Now the use of the steel structure of the increasingly high demand, so the adoption of steel structure on the material requirements are increasingly high, the use of steel structure, we mainly use what materials are used, according to the different uses, different components, the use of materials are also different. Main component materials: 1, strip plate: 8-32 thick. The width is 180-600. The length is less than 15000. 2, roll board: open plate, Kaiping pattern board. The general width is 1250.1500.1800.2000. The thickness is less than 16. 3. Hot rolled medium and thick plate. 4, H type steel: hot rolled H steel, high frequency welding H type steel. Sub component materials: 1, I-steel, channel steel, angle steel (equal side, unequal edge), round steel, screw steel, etc. 2. Cold bending hollow steel: square tube and rectangular tube 3, circular pipe: high frequency welded pipe, hot expansion seamless tube, seamless tube, spiral tube delivery period of 15-45 days, diameter mor…
