NSK bearings grinding, grinding wheel and the workpiece contact areas, consume a small amount of energy, a small amount of grinding heat, forming part of grinding zone instantly at low temperature. Applied linear static heat source heat transfer practice formula, calculation, or apply under the red line and thermocouple measurement test conditions temperature instantly, invented in the grinding zone instantly temperature can be as high as 1000~1500℃ in the 0.1~0.001ms. Instantly cold enough for the task looks deep surface of low-temperature oxidation, non-crystalline, low-temperature tempering, quenching for the second time, or even burn crack and other changes.
Dirt, if any, will result in installation difficulties, must be kept NSK bearing mounting surface and with parts for surface cleaning.
In addition to the mounting surface and the deep groove ball bearings with parts of surface cleaner, also note the axle, bearing block hole of the shell surface, face, shoulders and connecting components such as bushings, washers, did cover these places rust? If there is, you can use fine nail file, polishing cloth, and then install. Rolling bearings are precision components, its use has to be appropriately cautious. No matter how high-performance bearings, if used incorrectly, you will not get the expected performance. The precautions for use of NSK bearings are as follows:
1, the use of appropriate means of operation
Avoid with existing tools in place, you must use the right tools.
2, maintaining a clean deep groove ball bearing and its surrounding
Even the eyes cannot see the small dust, will bring bad influence to NSK bearings. So, to keep around clean, keep dust from intrusions into the bearing.
3, carefully using
In use for strong impact with a deep groove ball bearing, marks and creasing, becomes the cause of the accident. Serious cases, cracks, breakage, so care must be taken.
