NTN outer spherical bearing for regular maintenance - bearing knowledge

NTN bearing the correct maintenance and timely maintenance, is an important guarantee for normal operation of the highway mechanical aspects. If the outer spherical bearing maintenance, maintenance, can work thousands of disappear even longer; On the other hand, can make the outer spherical bearing service life dropped substantially, can appear even tile burning, holding shaft and other serious accidents. Usually NTN bearing lubricating oil temperature shall not be higher than 50 ℃. In order to ensure adequate and reliable lubrication, lubricating oil to timely or periodically check the oil level, keep the oil level within the prescribed scope. To keep clean, timely change according to the requirements of product quality. Foreign spherical bearing fault to particular case is particular analysis, and ruled out in time. Outside the spherical bearing of the common faults and processing methods are as follows. To make our NTN bearing and keep its long-term performance into full play, must earnestly to do regular maintenance ( Regular inspection) 。 Through proper periodic inspection, do early detection of fault, prevent accident arrangement is very important to increase productivity and efficiency. NTN bearing will be removed when check, use first method such as photography and then record the appearance. In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing. A, bearing cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame. B, rough washing, oil using a brush to remove grease or adhesive. If at this time in oil turn the outer spherical bearing, pay attention to the rolling surface due to foreign bodies such as damage. C, fine cleaning, slowly turn the NTN bearing in the oil, must be carefully. Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc. No matter use which kinds of detergent, often should filter clean. Immediately after cleaning, coating anticorrosive oil or antirust grease on the outer spherical bearing.
