INA bearings fixed way and knowledge - bearing lubrication

INA bearings fixed way INA bearing is fixed parts of machinery. INA rolling bearing performance depends largely on the material performance. Usually use low alloy and high purity of whole quenching chrome steel and crafting INA bearing ring and rolling body material. To withstand high impact load and alternating bending stress of INA bearings, using carburizing steel. INA bearings with inner ring and outer ring, as the world's top INA bearing, its fixed way how? 1. INA bearing shaft shoulder fixed INA bearing inner ring axial fixation rely on the shoulder and interference. Applicable to both ends fixed supporting structure. 2. INA bearings by fixed INA bearing inner ring by the shoulder and lock nut, axial fixation can afford little of two-way axial load. 3. INA bearing lock nut fixed INA bearing inner ring by the shoulder and lock nut, axial fixation and lock washer with locking, safe and reliable. 4. INA bearings fixed end thrust washer INA bearing inner ring by the shoulder and shaft end ring axial fixation. Shaft end ring on the shaft end with screws, screw locking device. 5. INA bearing sleeve is fixed on fixed set of inner hole of the radial dimension is compressed and clamped on the shaft, to implement the INA bearing inner ring axial fixation. INA bearing lubrication analysis INA bearing lubrication purpose is to reduce the INA bearing internal friction and the friction losses, the lubrication effect is as follows. 1. Reduce friction and friction losses. Formed the INA bearing ring, rolling body and touch each other part of the retainer, prevent metal contact, reduce friction and wear. 2. Extend the fatigue life. INA bearing fatigue life of rolling, in the rotation, good lubrication performance of the rolling contact surface, are extended. On the contrary, the oil viscosity is low, the thickness of lube film is not good, is shortened. 3. Discharge frictional heat and cooling cycle to oil can discharge by friction heat, oil, or from external heat from the cooling. Prevent overheating INA bearing, prevent aging oil itself. 4. Other also has to prevent foreign body into internal INA bearing, or to prevent rust and corrosion effect. Lubrication methods: INA bearing lubrication methods are divided into grease lubrication and oil lubrication. In order to make the INA bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. However, grease lubrication can simplify the structure of INA bearings around specialty.
