The importance of NTN universal joint bearing installation environment to use

NTN bearing in transport packaging or packing materials coated with anti-rust agent, rust during transport and storage, in order to prevent the bearing lubrication bearing this layer is not enough to be properly, but so lotions and other compatible lubricants, so in the gimbal bearings to install and use this kind of coating without clearance. Burr, foreign bodies, and can lead to poor bearing installation surface deflection NTN bearing. Universal joint assembly should pay attention to avoid cutting or damage to the surface of bearing installation or will lead to deviation, or to change the axial adjustment during the operation. Bearing installation, you should check the ring and shaft sleeve centerline axis vertical dial gauge fixed on the tank, will face a touch bearing, axis bearing raceway header, at the same time observe the dial gauge pointer, if the pointer deflection, ring and the axis of the shaft sleeve is not vertical center box shell hole deep, also can use the extension of dial instrument installation of universal joint bearing is correct, the seat can automatically adapt to the body, to ensure that the agency is located in the rolling up and down the wrong if, NTN bearing not only don't work, and cooperate with the surface will wear severely because of the difference of bearing seat ring and ring is not clear, the assembly should be careful, don't make a mistake in addition, the bearing race and a hole between 0. 2 - 0. 5 mm gap, to compensate for the machining of the parts, installation errors caused by inaccurate, operations center offset bearing rings, this space, in order to ensure the automatic adjustment, avoid contact friction of normal operation, otherwise the NTN bearing will cause serious harm. 1. Assembly site should be kept clean, no dust. 2. To avoid universal joint bearing from dust, moisture and contaminants - Pollutants have a bad effect on the running and service life of bearing. 3. Check the bearing hole and the shaft with the following: geometry and dimensional accuracy, and cleanliness. 4. For bearing ring mating surface coated with a little oil or a little fat. 5. To ensure that the shaft and bearing hole has a 10 degrees - Guide the chamfering of 15 degrees. 6. Don't be cool NTN bearing: condensation of water can lead to bearing and the bearing of mating surface rust. 7. After installation, loading the NTN bearing lubricant, check whether the bearing configuration is working properly.
