The smoothness of the roller bearing is in principle fundamentally the same as the smoothness of other rolling bearings; only the working conditions of the roller bearing are relatively poor; whether the operation function can be usefully developed depends largely on the smooth condition of the bearing.
The smooth method used for roll bearings is primarily grease smooth and oil smooth.
The smooth and smooth grease has a sealing effect; the sealing layout and smooth equipment are simple; the smooth grease is convenient; therefore, only the working conditions are required; the roller bearings are usually made of grease smooth.
The oil has a smooth cooling effect; it can remove dirt and moisture from the bearing. The roller bearing adopts a smooth and smooth oil method with smooth oil supply, smooth fuel injection, smooth oil mist and smooth oil and gas.
Smooth pressure supply is the most useful smoothing method for roller bearings under conventional speed.
Smooth injection is to smooth the smooth oil through a nozzle mounted on one side of the bearing to the inside of the bearing for smoothing; usually used in high-speed roll bearings; perhaps where the pressure supply is smooth and the cooling demand is not satisfactory.
Smooth spray is to spray the dry compressed air rich in oil mist to the inside of the bearing for smoothness; the oil consumption is small; because of the action of air; the cooling effect is extremely strong; it is mainly used for large roll bearings with high rolling speed and high rolling precision. Perhaps used for roll bearings that are not often disassembled in the bearing housing.
Pressure supply and smooth oil injection require the installation of inlet and outlet pipes, smooth pumps, oil reservoirs; sometimes smooth oil coolers are required; therefore; the cost is higher; usually the roller bearings are less used.
