Work conflicts are greater.
The vacuum impregnation method is used to store oil in the oil hole of the inner diameter surface of the bearing; the oil film is smooth after work conflict heat generation.
The fan is fixed by straight method; it is better to use.
2) Single ball bearing accuracy second.
The service life is 30,000 hours; the calculation: 1250 days; the 3. 4 years line and point touch are available.
Work conflicts are second.
The application method has the characteristics of oil-bearing bearing/double ball bearing; the workload is mainly on the ball at the front end; and the copper at the back end is the effect of feeding the fulcrum; and the effect is adjusted according to the effect of the ball positioning.
The fan is fixed in a straight direction; the application is better.
3) Double ball bearing precision with the highest service life of 50,000 hours; calculation: 2084 days; 5.7 years bearing and shaft relative motion for point touch.
The movement conflict is small.
The inner ball of the bearing is used to cooperate with the smooth grease for the reverse movement under the position of the holder.
The fan can be fixed in any direction.

The IP rating of Led Vapor Tight Fixtures is 66. It is dustproof, waterproof, anti-corrosion, and anti-UV. It can effectively prevent the lamp body from being easily oxidized and broken after exposure. The integrated design makes installation more convenient and quicker. It does not need to be installed and connected in series after the lamp body is open like the traditional three-proof light. So it can effectively shorten the construction period and reduce labor costs.
There is a respirator at one end of the lamp body, which can avoid thermal expansion and contraction when the lamp body is working, and water droplets appear on the wall of the lamp body, which affects the service life of the lamp beads.
Our LED Tri-proof Light are connected in series without the use of tools. Cylindrical design, which make cleaning more easily.
