Product Description

      These bearings mainly include two types: bearings used in low temperature and bearings used in normal temperature. The minimum temperature of low temperature bearings is -253°C.

   High-temperature & High-speed Bearing                                                                                                     
        High-temperature & high-speed bearing can resist a high temperature of 300°C. The highest speed of ball bearing can reach 60,000r/min. And the highest speed of cylindrical roller bearing is 50,000r/min. It can be lubricated by oil. It has a high Dm·n value and a good dimensional stability in high temperature. It is mainly used in the application with the highest requirement, such as gas turbine engine.

Angular contact ball bearings :

       The ZYS precision angular contact ball bearings for spindles, have four size series,718,719,70 and 72. With the same inner diameter, the outer diameters and the widths of 718,719,70 and 72 series increase in turn.
      ZYS precision angular contact ball bearing with 15 ° (C) and 25 ° (AC) contact angles. As for the angular contact ball bearings, the bigger the contact angle is, the greater the axial load capacity is, but the lower the limited speed of bearings becomes. Therefore ,the spindle, with high speed and small axial load ,should adopt the 15 ° angular contact ball bearings,whereas the 25 ° angular contact ball bearing should be adopted.
     ZYS precision angular contact ball bearings with high-speed angular contact bearings (standard series), super-speed angular contact ball bearings, high-speed sealed angular contact ball bearings and high-speed spindle bearings.
