The ball bearing of major groove has a representative antifriction bearing most, have wide use range. Suitable for the operation of the even extremely high rotational speed of the high rotational speed, and very durable, do not need to safeguard frequently. The coefficient of friction of this kind of bearing is small, the terminal rotational speed is high, simple in construction, make low cost, it is apt to reach the great to make precision. Dimensional range and form change variously, apply to trades such as accurate instrument, electrical machinery, car, motorcycle and general machinery with low noise,etc., use the most extensive kind of bearing in the mechanical industry. Mainly bear radial load, can also bear a certain amount of axial load.


As to basic specified dynamic load
1. The bearing refers to the pure radial load entad
2. The thrust ball bearing refers to the pure axial load
3. The thrust bearing means entad that producing pure radial displacement gets the radial weight


Install and safeguard
Pay attention to the main point
Guarantee from using the angle the bearing should pay attention to the following several points to work reliably:
1,Improve lubricated quality, control the pressure, temperature and flowrate of the engine oil, strengthen the engine oil to filtrate.
2,It accords with specified fuel and lubricating oil to adopt.
3,Control the temperature state of the diesel generator set, it is all unfavorable to work in with overheated supercooling cases. Leng Tian, the diesel engine should be preheated first before start, and rotated the crankshaft by hand to make the engine oil enter and grit the surface.
4,The bearing, journal surface condition and geometric shape should get the assurance strictly.
5,The bearing clearance should be appropriate, the generating set over assaults, too lubricate badly small, may burn tiles.
