Choose the type of rolling bearing reference these key points

To teach you how to choose the right of the rolling bearing temperature properly choose a high temperature rolling bearings of different types, like this a few key elements: 1, the size of the load condition of high temperature bearing load, the direction and nature according to the main types of high temperature bearing is selected. High temperature load is small, smooth, optional ball bearing; When there is a big shock load, high temperature should be choose from roller bearings; When high temperature only by radial load bearing, the radial contact ball bearing with high temperature or the temperature of the roller bearing selection, for example; Only when under axial load, should choose high thrust bearing; Through the radial and axial load of high temperature bearing, angular contact bearing temperature. Large axial load, the larger contact Angle should choose high temperature bearing, the radial structure can also be in combination of the high temperature and high temperature bearing and thrust bearing, for if necessary. Thrust bearing temperature should be aware of unacceptable radial load, high temperature of cylindrical roller bearing axial load is unacceptable. 2, high temperature the speed of the bearing has the same effect if high temperature bearing size and accuracy requirement, the ball high temperature bearing limit rotational speed is higher than roller through high temperature bearing, so when the speed is high and can request a high rotation precision, choose the high temperature ball bearings. High temperature thrust bearing limit rotational speed is low. When the high working speed, axial load hours, can be used high temperature high temperature angular contact ball bearing or deep groove ball bearings. High temperature bearing for high-speed rotation, in order to reduce the centripetal force foreign roller ring raceway, should choose high temperature bearing outside diameter smaller and rolling body. General high temperature bearing should guarantee work under limit speed. If work at a faster rate than high temperature bearing limit speed, by improving the high temperature bearing tolerance grade, appropriate to increase the radial clearance, can meet the requirements. 3, self-aligning properties of high temperature bearing inner and outer ring deflection Angle should be controlled within the limit value, otherwise it will increase the additional load of high temperature bearing, reduce its service life. For the poor rigidity or device shaft, high temperature bearing inner and outer circle axis Angle is bigger, should be chosen from a high temperature bearing. High temperature, such as spherical bearings ( 1) , high temperature spherical roller bearing, 2) And so on. 4, allowing space when the axial size is limited, you should use a narrow narrow or the temperature of the bearing. When the radial size restrictions, temperature should choose small rolling element bearings. Radial size small and radial load is bigger, the request of the high temperature of needle bearing. 5, loading performance conic roller through the high temperature impact bearing ( 3 classes) And cylindrical roller bearings (linked to hot weather N class) Loaded inside and outside the circle do not open compare with lunch. 6, economy to meet the student to utilize can request should choose different design as far as possible under the condition of low price of high temperature bearing. Under ordinary living conditions the ball high temperature bearing price below high temperature roller bearing. The higher the accuracy requirement of high temperature bearing grade level, the higher the price also. 7, other requests in size, and high precision bearing with low price of the same high temperature deep groove ball bearings. Same model, size, high temperature deep groove ball bearing with different levels of tolerance is about PO: P6: P4: P2 material 1:1. 5:2:7:10. If there is no special requirements, common high temperature precision bearing should choose as far as possible, as long as there is higher requirement on the rotating accuracy, high temperature bearing.
