High temperature bearing selection considerations!

A, dimension can generally high temperature bearing device of the space is constrained. In most cases, the diameter of axle ( Or bearing inside diameter) Is based on mechanical or other planning constraints. So bearing type and scale of selection is based on the inner diameter of the bearing. Thus, the primary measure of bearing table are compiled based on the international scale diameter scale. The measure method of high temperature bearing is various, good use scale bearing in the plant planning. High temperature bearing load, the load on the bearing, its nature, intrusive, direction is changeable. In general, the basic load rating on the dimension table are displayed. Axial load and radial load, and so on, but also for choosing the suitable for bearing the important elements. When the equal of the scale of the ball and needle bearing, needle roller bearings generally have higher load capacity and accept the larger oscillation and impact load. Second, speed of rotation speed is based on the type of high temperature bearing, scales, precision, cage type, load, smooth method, and the cooling method elements such as certain. Bearing on the table lists the dimension precision bearing promise speed under the condition of oil and grease smooth smooth. Generally, active deep groove ball bearings, self-aligning ball bearings and cylindrical roller bearings are used in high speed occasions. Three, high temperature tolerance dimension precision bearings and rotating accuracy is based on ISO and JIS scale. For machines, high-precision and high-speed operation for using grade 5 or above precision bearing, deep groove ball bearings, angular contact ball bearings and cylindrical roller bearings are used in high running accuracy mechanical. Rigid, when bearing to move body and contact pressure, will produce elastic deformation. Some mechanical demand will be elastic deformation to small. Roller bearing is smaller than ball bearings produced by elastic shape variables. Four, exerted pressure in some cases the bearing to the rigid this program to add commonly used in deep groove ball bearings, angular contact ball bearings and tapered roller bearing inner and outer circle of bias, winding shaft and the shaft or the bearing box tolerance changes, fault leads to the inner and outer circle eccentricity. To avoid offset Angle through the large, self-aligning ball bearings, actively take the initiative to spherical roller bearing, or self-aligning bearing is better. Voice frequency and torque, move bearing are made according to produce high precision measure, so the voice and the torque is small. Deep groove ball bearings and cylindrical roller bearing used for in low voice, low torque has special requirements of the occasion. Five, the device and open it some applications demand often open and device, to ensure that can be tested and repaired. Inside and outside the circle can be bearing separation devices such as: cylindrical bearings, needle roller bearings, and tapered bearing fits for this occasion. Cone pass self-aligning ball bearings, initiative and active spherical roller bearing under the help of shaft sleeve, also simplify the process of the device.
