High speed precision NSK bearings, mainly used in the high-speed rotating situation of load lighter, NSK bearings require high precision, high speed, low temperature rise, low vibration and service life.
Often for high speed motorized spindle bearing parts installed in pairs, is the key to the high-speed motorized spindle surface grinding machine fittings.
The main technical indicators: 1.
NSK bearings precision index: more than GB / 307.
1 -
2 94 p4 level precision.
High-speed performance indicators: dmN value of 1.
3 to 1.
8x106/min 3.
The service life (
On average)
:> 1500 h high speed precision NSK bearings service life had a lot to do with the installation, should pay attention to the following: 1.
NSK bearings installation should be clean, clean room, NSK bearings should be carefully selected, NSK bearings with baffle passes through grinding, and in keeping the baffle on inner and outer contour under the premise of baffle parallelism should be controlled below 1 um.
2.
NSK bearings should be cleaned before installed and when cleaning inner ring ramp up, flexible hand induction, no stagnation, air-dried, into the specified amount oil, if oil mist lubricating oil should be in a small amount of oil mist;
3.
NSK bearings installation should use specialized tools, force uniform, do not knock;
4.
NSK bearings deposit should be clean and ventilated, non-corrosive gas, more than 65% relative humidity, long-term storage should be rust on a regular basis.
