As a key component of mechanical equipment, bearings play a role of load bearing and support, ensuring that the equipment runs smoothly and efficiently under various load conditions. Whether in motors or gearboxes, bearings must be able to withstand the radial and axial loads generated during operation. However, when the actual load of the bearing exceeds its design limit, overload occurs. Overload not only causes premature failure of the bearing, but may also cause more serious equipment failures. What is bearing overload? Bearing overload means that the load borne by the bearing during use exceeds its rated load capacity. The rated load is usually the theoretical calculated value of the bearing manufacturer under standard conditions, and improper use in actual work, such as load exceeding the limit, sudden impact, etc., will cause overload. Overload may occur in the long-term operation of the equipment, or it may occur instantly under sudden impact loads.
