   Deep groove ball bearings are most commonly used bearing. It's simple, easy to use. Mainly used to bear radial load, but increase the bearing radial clearance, with certain features of the angular contact ball bearings can withstand radial and axial load. When should not be used in high speed and thrust ball bearings, it can also be used to bear pure axial load. The same deep groove ball bearing sizes of other types of bearings, bearing friction coefficient is small, high speed limit. However, the impact of intolerance, not suitable to withstand heavy loads.
   We recommend the following models: 71912C / DB bearing MF117ZZS bearing C31 / 630KMB + OH31 / 630HE bearing 5308ALLB bearing 7018C / DT bearings NJ306 + HJ306 bearing YET206-101 bearing BA2112Z 6907ZZE bearing 30332 bearing bearing 4100 bearing bearing NSK 6920NR bearing CFE30VBR
   I also recommend NSK 6920NR bearing purposes: horizontal lathe, grinder, machining centers, fan, CNC lathes, blowers, machine tools, magnetic separation equipment, special tools, grading equipment, graphite heat exchanger, fixture , plate heat exchanger, plug-in machines, fillers, and other purposes.
   nsk bearing temperature, generally bearing chamber outside temperature can be inferred, if the use of the hole can directly measure the temperature of the bearing outer ring, is more appropriate. Generally, the bearing temperature rise slowly as the bearing operation after 1-2 hours to reach steady state. The normal temperature of the bearing due to heat capacity, heat capacity, speed and load of the machine is different. If the lubrication, install the appropriate department, the bearing temperature will be rapid rise, there will be abnormal high temperature, then must stop running, take the necessary precautions.
