High temperature bearing of choose and buy should give full consideration to the main economic factors

The main factor that should consider when buying high temperature bearing 1. Load conditions is to choose the high temperature load bearing the main basis, usually should be based on load size, direction and nature to choose high temperature bearing. 2. Under normal conditions of the payload size, high temperature roller bearings, because it is a line contact, carrying capacity is big, suitable for receiving a large load; Due to high temperature point contact ball bearing, bearing capacity, suitable for light, medium load. For bearing, high rigidity, superior rotating accuracy, use a small outer diameter of the ball in the high temperature and low temperature friction torque of bearings manufacturer. Using hollow shaft to ensure lightweight space and wiring. 3. Load the main direction of pure radial force, appropriate chooses heat deep groove ball bearings, cylindrical roller through high temperature lead to bearing or needle roller temperature and bearing, and thinking can we choose self-aligning bearing high temperature. Pure axial load effect, using high temperature for thrust ball bearing and thrust roller bearing high temperature. Radial load and axial pressure load can combine, ordinary companies choose high temperature high temperature angular contact ball bearings and tapered roller bearings, both on the high temperature bearing over contact Angle. Increase students accept no axial load capacity to development and progress. If larger changes radial load and axial load is small, also can choose high temperature deep groove ball bearing between the inner and outer ring and has a guard of cylindrical roller bearing high temperature. If the axial load produce larger and radial load is small, can choose different heat thrust angular contact ball bearings, thrust taper roller through high temperature lead to bearing. High temperature bearing adopts high temperature bearing smooth and there is no way, divided into oil and grease smooth smooth. In order to make high temperature bearing can play an important function, first, to choose a suitable enterprise use economic conditions, using the research purpose of smooth processing measures. If only consider smooth, oil slick smoothness is preferred. , but there can be simplified fat smooth expertise of the structure of high temperature bearing surroundings will be fat and oil slick smooth interest. 4. Loading properties have impact and load, appropriate chooses roller bearing by high temperature. 5. High speed performance of ordinary trade friction moment of small, small heat of high temperature impact bearing for high speed machining performance is good. Ball roller by high temperature and high temperature lead to bearing than bearings have higher speed limit theory, therefore, high speed should be priority to the development of thinking when we choose the ball high temperature for bearings. Radial load is small, using high temperature deep groove ball bearing: radial load large, choose a cylindrical roller bearing high temperature. To combine the actual load, load hours, choose high temperature angular contact ball bearing; High temperature load is big, the selection of tapered roller bearings and cylindrical roller bearing high temperature and high temperature angular contact ball bearings portfolio. In the same inside diameter, outside diameter size is smaller, the lighter the small roller, roller during operation effect on the outer ring of the centripetal force is small, and therefore more suitable for the enterprise high requirements under the working speed. Working in certain economic conditions, the target speed is high, appropriate chooses a kind of high temperature bearing diameter is 8901, respectively. The data and structure of the scaffold has a great influence on the high temperature the speed of the bearing. Described in solid nut holder of the rotating speed of stamping nut gripper described above allow rotation speed. High-speed heavy high temperature bearing need to check the limit speed. 6. Axial winding performance general machinery work, due to mechanical friction or the relationship between the working medium, the shaft heat bilges cold shrink. When choosing high temperature bearing structural type, axis should be the possibility of uranium. A: on this regard, consideration should be given option under the high temperature bearing a: no
