R - NMB bearing's official website ZZ series of handling and storage precautions NMB bearing handling and storage: 1, ball bearing for precision parts, the need to avoid foreign bodies to enter. Please attach great importance to the use environment of cleanliness. 2, bearing and shaft, the fixed seat available between a variety of methods, fixed, when assembly, please pay attention to the following matters. No matter how to 'match' must be on the bearing and shaft, bearing, and the center of the fixed seat for vertical installation. The interference with the quantity, to 'cooperate' side of the inner ring and outer ring exert pressure into the vertical force. In addition, the pressure into ShiJiaJing load, and do not exert impact load with a hammer, etc. Toward a direction of bearing Angle on inner and outer gap is too large torque load, load location or at the wrong style, bearing internal may produce indentation. For dust cover, sealed type, do not impose load on shield and sealing. 3, shaft and fixed operation, if there is foreign body attached shaft and fixed, the assembled bearing will not be properly installed and lead to axis deviation. Axis and fixed injury occurs. In addition, the axis deviation pressure under the condition of pressure, can lead to shaft and fixed cause a new injury. Ball bearing inner and outer ring wall thickness ( The thickness of the section) Very thin, 'cooperate' with amount of interference, the shape of the shaft and fixed directly by the ball bearings inside and outside circle axis channel slot replication. Especially roundness is low and flat marks, damage, inside and outside the circle is easy to deformation, and leads to the noise and shorter service life and navigation wurui remind you must pay attention to. 4, the assembly after handling, shaft on the motor with bearing bulge and rear axle assembly is still prominent, impose excessive load and impact load on axle, bearing internal may produce indentation. In addition, if applying vibration may produce microtremor wear trace.
