NSK bearings imported in operation after a period of time, will inevitably have a need to maintenance or damage to the replacement, the development of mechanical industry in the early for the popularity of professional knowledge is not enough, insufficient awareness of safety operating rules, the author will talk to you today about bearing knowledge points.
We recommended for you to the 6901 zz bearing type, 16001, 6001, 6001, ddu, 6201, 6201 zz, 6201 vv, vv, 6902, 6902, 6802 zz.
NSK bearings generally applies: mining geophysical exploration equipment, aeration equipment, pump, soldering stations, low noise type cooling towers, oil cooler, linear guide, copper smelting equipment, shearing machine, wheel, etc.
Bearing grease with 1 what are the advantages of the lubrication device is simple.
If you use a sealed bearing or not sealed bearing does not need to add fat, does not require any additional lubrication device (
Oil lubrication system needs, by contrast, oil pump, oil pipe, tank, etc. )
。
2 grease is not easy to leak, bearing seal structure is simpler, 3 bearing maintenance, maintenance is convenient.
4 grease sealing function, can prevent external dust, water and other impurities into the bearing.
5 easy to improve the purity of the machinery.
High hardness and elastic modulus of imported bearings.
Silicon nitride high hardness roller can improve the abrasion resistance, stiffness of bearing in the pollution of the environment and service life.
Steel rolling body excessive rolling solid pollutants, due to plastic deformation, will be in the race and rolling elements have bump is formed on the edge of the indentation.
Due to continuous excessive rolling roller convex edge, high local stress will lead to spalling, causing premature failure of the bearing.
However, hybrid ceramic bearing on excessive damaged areas of the different rolling.
Because of the silicon nitride high hardness, scrolling experience is creasing the convex edge smooth, until the raceway restore smooth, it will reduce the chance of local stress and spalling, significantly extend the service life of bearing.
