2, the type and size of the load when subjected to shock load or heavy load; usually should choose more strict cooperation than normal, light load. About the radial bearing load, the radial equivalent dynamic load PR and radial additional movement The ratio of load CR is distinguished; the greater the load, the greater the cooperation and the surplus. The load size PR/CR light load is less than or equal to 0. 07 The normal load is greater than 0. 07 ~ 0. 15 Heavy load is greater than 0. 15
3. The size of the bearing scale follows the increase of the bearing scale; the selected interference cooperation is more profitable; the gap between the gap cooperation is larger.
4, bearing clearance using interference cooperation will lead to the reduction of bearing clearance. Calcined æ¦˜æ²§ ç¬¾å²¢ ç¬¾å²¢ æŒ æŒ æŒ å¦’ å¦’ å¦’ å¦’ è¡¤é—¶è¤‚é¡èž… â‰¡è¡½æµœ â‰¡è¡½æµœ â‰¡è¡½æµœ â‰¡è¡½æµœ å²¢ å²¢ å²¢ å²¢ å²¢ å²¢ å²¢ å²¢ å²¢ å²¢
5, the influence of other factors on the shaft and bearing housing data, strength and thermal conductivity, external and thermal conduction methods and heat in the bearing; support devices and adjustment functions, etc. affect the selection of cooperation.

Advantages of greenhouse LED Grow Light .
- Energy saving. LED Grow Lamp is efficient light only consume less energy put output powerful light. Environment friendly and saving bill.
- Long lifespam. LED is durable and with long life 50,000 hours. Which also ensure you lower maintenance cost. Traditional HPS MH grow lights is very easy to fail and almost need to change each year.
- Better for plants growth. LED grow lights are usually with full spectrum, Plants can use nearly all the light emitted from led grow lights. But usually only 35% of light generated by MH HPS is useful for plants growth.
- Low heat output. LED grow lights produce very little heat, and they usually with fans or efficient dissipation heat sink. Ensure better growing environment to plants. Traditional lights usually delivery lots of heat. It's very hard for plants especially in summer.
