In addition to open deep groove ball bearings, FAG bearings are also supplied with double-sided dust caps (non-touch seals) or double-sided seals (touch seals) as the basic type of FAG deep groove ball bearings.
FAG deep groove ball bearing with dust cover FAG bearing with dust cover (suffix. 2ZR outer diameter is less than or equal to 22mm. The limit speed of 2Z is ​​lower than that of open-type imported bearings.
FAG bearings with sealed seals for FAG deep groove ball bearings (.2RSR; 2RS for bearings with an outer diameter of not more than 22mm) are limited by the allowable sliding speed of the sealing lip.
Non-touch with RSD type is sealed bearing and non-touch type. 2R type sealed bearings have the same outstanding conflict characteristics. When the inner ring is fixed and the outer ring is changed; the lubricant loss of the RSD type sealed bearing is lower than that of the ZR type sealed bearing.

The IP Explosion-Proof Camera is a digital device based on network transmission. In addition to the ordinary composite video signal output interface BNC, the IP explosion-proof camera also has a network output interface, which can intervene the explosion-proof camera into the local LAN. Each IP explosion-proof camera has its own IP address. , data processing function and built-in application software; IP compression camera adopts image compression method can be divided into H.264, MPEG4, MJPEG, etc. as the mainstream compression mode, IP explosion-proof camera has the advantage of transmission compared with traditional explosion-proof camera; IP The main performance indicators of explosion-proof cameras are: definition, dynamic range, color reproduction, signal to noise ratio, image coding compression algorithm, etc.
