 When NSK Bearings installation should be especially careful with cylindrical and tapered bore can be operated by watching whether NSK bearings after installation to determine proper installation is correct. Why so careful? Since it is often a little carelessness will damage NSK bearings, so as to bring NSK Bearings installation and operation precautions.

Because NSK Bearings structure, with the condition varies, generally, due to multi-axis rotation, so the inner ring needs interference fit. Cylindrical bore bearings, the use of press pressed into, or by hot charging method. Cone occasions, mounted directly on the tapered shaft or sleeve installation.
When mounted to the housing, generally with more clearance, the outer ring interference, usually pressed into the press or shrink fit method also cooled installation. With dry ice as the coolant, install the shrink fit the occasion, moisture in the air will condense on the surface of NSK bearings. Therefore, proper corrosion protection.
 
 
NSK Bearings check the temperature generally from the outer shell seen speculation. But the use of the hole, direct measurement of bearing outer ring temperature, more accurately. Bearing temperature operation was beginning to rise, without exception, are usually stable for 1 to 2 hours after. If the result of poor installation or the like bearing, bearing temperature will soar, abnormal high temperature. The reason such as too much lubricant, the bearing clearance is too small, poor installation, seal friction and too big. High-speed rotation of the occasion, bearing lubrication method of choosing the wrong and so is its cause.
