Choose NTN miniature bearing with stable running five skills

In order to be able to achieve in the axis ( Rotating condition) Load and limited movement system relative to the bearing seat ( Static system) The basic task of the location, NTN bearing has played a key role. Cooperate with miniature bearing with role is to make the NTN bearing stationary ring and rotating ring can respectively and installation position of bearing seat ( Stationary part) And the shaft ( Rotating parts) Close together. Both on the shaft and bearing, miniature bearing are required in the radial, axial and tangential direction to three directions such as fixed position. Is through the positioning of the radial and tangential NTN bearing ring tight fit to realize, however the axial positioning only in a few cases with tight fit; For use in the miniature bearing, how can we make sure it could be stable operation? Today will invite used to introduce the five skills: a, bearing clearance should be appropriate, too big impact, is too small, poor lubrication, may cause tile burning; Second, NTN bearing and shaft neck surface quality and geometry must be strictly guaranteed; Third, improve the quality of bearing lubrication, control oil pressure, temperature and flow rate, strengthen the oil filtration; Four, in the case of overheating too cold work is unfavorable for miniature bearing, so to control the temperature of the diesel engine. Cold day, should be preheated before starting of diesel engine, with the hand cranking make the oil into the friction surface. Five, conform to the provisions of the fuel and lubricating oil. In use, did more than five miniature bearing operation effect will also get corresponding improvement.
