Weihai slewing bearing 133.50.4500.002 low price

Weihai slewing ring bearings... are cheap in stimulating the amount of rolling load generated. When a load-bearing radial load is carried, the amount of rolling it carries will change slightly during operation, which.... This causes the direction of the load offset. The resulting vibration is unavoidable, but all rolling elements can be preloaded to reduce axial loading. During operation, rolling across a damaged slew bearing component produces specific vibration frequencies. Frequency analysis can identify damaged bearing components. This principle has been used in condition monitoring equipment to detect bearing damage. The temperature will rise sharply and cause abnormally high temperatures. The reasons include too much lubricant, too small bearing clearance, poor installation, excessive friction of the sealing device, etc. In the case of high-speed rotation, the wrong selection of imported bearing structure and lubrication method is also the reason. The relationship between the shaft and the bearing, in close contact with the bearing ring, is compatible with shape deformations in adjacent areas. Distortion may cause vibration during operation. Therefore, the tolerances required for the machining of slew bearings and shafts are very important. If you're operating in a contaminated environment, impurities can get into the rolling bearings. Vibration depends on the number, size and composition of rolling impurity particles. Although the frequency does not produce a typical form, the reasons include poor lubrication, poor shaft or bearing seat accuracy, bearing damage, foreign matter intrusion, etc., but you can hear an annoying noise. The inspection is generally carried out in two situations. The first situation is that small bearings and small machines can be rotated by hand to determine whether the bearing rotates smoothly. In this case, it is generally necessary to check whether the bearing is not running smoothly due to foreign matter, indentations, scars, etc., uneven rotational torque due to poor installation, poor processing of the mounting seat, too small clearance, installation error, sealing friction The resulting torque is too large, etc. The second is that large machinery cannot be rotated manually. In this case, large machinery cannot be rotated manually, so the power is turned off immediately after starting without load and inertial operation is performed. Check for vibration, sound, contact between rotating parts, etc. After confirming that there are no abnormalities, enter power operation.
