Bearing limit speed

Users in the process of bearing the choose and buy, no doubt will take into account the bearing limit rotational speed is how much? Never choose to suit oneself machine speed bearings, bearing factory in jiaxing today for you to popularize the basic knowledge of bearing limit speed, let the masses of users to have a better understanding of the bearing. The speed of the bearing can be achieved are limited, bearing limit speed of high and low and the type of bearing, lubrication, accuracy, clearance, size, load, cage and cooling conditions, and other factors. All kinds of bearing limit speed on the rolling bearing product samples bearing size and performance in the table, they are in grease lubrication and oil lubrication ( Oil bath lubrication) Under the condition of certain, its scope of application: ( 1) Standard ( G） Tolerance level bearing; ( 2) Centripetal bearing only bear radial load bearing only bear axial load; ( 3) Normal lubrication cooling conditions. ( 4) P≤ 0. 1 c ( C the basic dynamic load rating of bearing) ； ( 5) Rigidity of the bearing and the shaft; When the bearing P≥ 0. 1 c load conditions during operation, because the rolling element and raceway contact surface between the contact stress increases, the bearing temperature rise, the performance of the lubricant is relatively worse, therefore, the limit of bearing rotating speed will be reduced accordingly. For C/P≥ The range of 10, due to the lower limit speed is very small, so it can not be considered, namely the f1 = 1. Centripetal bearings for joint under load, because of its number increasing, the load of rolling body friction resistance increases, higher calorific value, lubrication and cooling conditions, but also increase the force ACTS on the cage, therefore, must according to the size of the bearing type and load Angle, cut bearing limit speed multiplied by a coefficient of f2. If selected bearing limit speed cannot satisfy the use requirement, some technical measures to improve and can be used to achieve a satisfactory requirements. Such as increasing bearing poor tolerance level; Appropriate increase of clearance. Use special materials and the structure of the improved cage; Change the lubrication method, such as lubrication oil and gas, oil mist and spray; Improve the cooling condition, etc. Above is jiaxing bearing factory for you to introduce the basic knowledge of bearing limit speed, I believe you to be of help, more knowledge of bearing welcome call jiaxing bearing group sales co. , LTD. , we will serve you wholeheartedly.
