High-speed, high-temperature conditions; when the grease is not suitable, it can be smoothed with oil. Smooth oil circulation; can take away a lot of heat. Viscosity is an important characteristic of smooth oil; viscosity fineness directly affects the smooth oil flow and the oil film thickness between the conflicting surfaces; The viscosity of the smooth oil at the working temperature of the bearing is usually 12-15cst. ​​The higher the speed, the lower the viscosity should be selected; the heavier the load, the higher the viscosity should be selected. The commonly used smooth oils are mechanical oil, high-speed mechanical oil, turbine oil, compacting oil, transformer oil, cylinder. Oil, etc. The oil smooth method includes:
a. Smooth oil bath is the most common smooth method; suitable for low and medium speed bearings; the part of the bearing is dipped in the groove; the smooth oil is taken up by the rotating SKF bearing parts; then it flows back to the oil groove. The oil level should be slightly lower than the middle of the lowest roll. .
b. Smooth drip is suitable for demanding supply of smooth oil bearing parts; the amount of dripping is usually one drop every 3-8 seconds; too much oil will cause the bearing temperature to increase.
c. The circulating oil is smooth and the oil is pumped to the bearing parts; the smooth oil after the bearing is filtered and cooled, and the circulating oil can take away certain heat; the bearing is cooled; therefore, the method is suitable for bearing parts with higher rotational speed.
d. The spray is smooth and boring and compressed air is mixed with smooth oil by a sprayer to form an oil mist; in the ejecting bearing; the air flow can be used to cool the SKF bearing and avoid intrusion of impurities. This method is suitable for high-speed, high-temperature bearing components.

Pull-out Faucets take up much less headroom than a pull down model, making it a great choice for kitchens with cabinet space above the sink. If you have a shallow sink, a Pull-out Faucet may be more beneficial, as it has less splashback than the pull-down model.
