Vesconite Sheet Rod Bushing (Standard Vesconite - Black) is a specialized thermoplastic made from internally lubricated polymers. Proved since the 1960's as an exceptional bearing material in demanding conditions, Vesconite gives low wear even in dirty or unlubricated conditions. Up to 10 times the life of bronze in dirty conditions. Vesconite has high dimensional stability and does not swell in water, in contrast to most synthetic materials which swell in water. For example, nylon swells up to 3% in water and softens.
Vesconite Tube Rod are produced in Standard 1 meter lengths (39.37 inch = 3.28 feet)
Vesconite Sheet Rod Bushing is available in Hollow bar (Bushing), Solid bar (Rod) and Plate (Sheet) form. It is easily machined and we also provide a fully finished machined bush/component service.
Vesconite Rod Sheet Features :
High Load Bearing Strength - VESCONITE has very low creep rates under design loadings of 4,351 psi (30 Mpa). Much higher load capacity than nylon and elastomers.
Dimensional Stability - The thermal expansion factor of VESCONITE is only 2.5 times that of bronze, lower than many of the competitors. HDPE and nylon is 5 and 10 times greater, respectfully.
No Water Swell - Only 0.5% at ambient. Negligible in sizing calculations. Most of the competition is way above this. Nylon has a 9-10% water swell. Elastomers have a 1.3 - 3% water swell. Phenolics are at generally at 1.6 - 2% water swell. Water swell is one of the primary causes leading to shaft seizure.
Low Friction - Dynamically, about half that of bronze and nylon. This allows for greater combinations of loads and speeds. Greasing of VESCONITE further deceases friction, allowing higher speeds and improved performance. Water is also an excellent lubricant for VESCONITE bushings.
Abrasion Resistance - VESCONITE provides outstanding abrasion resistance resulting in many times longer service life, when compared to bronze. It is also outperforms other products in poor lubrication and dirty conditions.
Longer Life of the Mating Surfaces - The wear of metal pins and shafts is reduced by up to 90% when VESCONITE bushings are used. This fact, alone, justifies the use of VESCONITE ΓÇô less maintenance.
Chemical Resistance Vesconite is highly resistant to diluted acids, organic solvents, oils, and petrol. It has limited resistance to strong acids and strong alkalis.
Temperature Resistance -Vesconite can withstand continuous temperatures up to 212°F (100°C) dry and 176°F (80°C) wet, with momentary peaks above this. Above 158°F (70°C) an expansion gap must be incorporated into the bearing design for a proper use.

The wireless bridge developed by Tengyuan Chitoo has double security features. Then how do we use its features to encrypt it? The editors hereby give you a brief introduction. The wireless bridge needs to operate through the client software of the wireless monitoring system. Generally, operations are performed by logging in with a user name and password. This encryption method is often referred to as WEP. WEP is a data encryption device based on a 40-bit shared key code. With this device, people with ulterior motives can hardly invade the network. WEP has multiple encryption methods, and its encryption. Not in the IEEE 802.11 standard. You can use multiple WEP passwords. A group of fixed WEP passwords is not very secure. Using multiple passwords improves security. Higher-level encryption can be used. Current encryption technology can provide 64-bit and 128-bit encryption methods. Usually 128-bit encryption is used. WEP encryption can encrypt data files before they are transmitted. Those who use network hacker technology, Unable to get the real information of the data file. It is even safer to change your password regularly.
There is also WPA encryption. This WPA encryption feature has higher data requirements than the WEP encryption feature and it is more difficult to invade than WEP. Windows XP SP2 already supports WPA encryption. This security encryption system has two encryption methods. These two methods are Pre-shared key and Radius key. Pre-shared key has TKIP and AES. RADIUS key uses RADIUS. The server performs authentication. This method can dynamically select TKIP, AES, and WEP for encryption. This is the two different setting methods of the encryption device, which encrypts the wireless monitoring device and makes the user more secure to use the wireless bridge for secure data transmission.
After the client software sets the password for the superuser, a new limited user can be created. No need to assign the right to playback the video and turn off the system to the restricted user, and then use the limited user to log in to the client software. This setting is limited. The user plays back and closes the system's permissions in the software. There is also a possibility that the software is minimized to the tray, or through other ways to return to the windows desktop, through my computer to enter the hard disk where the video exists, click the video file Can play. This setting is more comfortable for the user. This approach can also be said to be more secure. The above is the editor's commentary on the setting of the encryption device of the wireless monitoring device. If it is not appropriate, please give advice and correct me.
With the development of the security monitoring industry, the technology of wireless bridges has gradually matured. The type of wireless bridge production has become broad and has been developed in different industry fields. Wireless LANs exist in every corner of the world, and they have gradually entered the tens of millions of households. The security of wireless surveillance systems is also worrying. Within the scope of wireless network signal transmission, some people with ulterior motives use the network technology to access the signal transmission range, intent to tamper with, steal, or even damage the user's data file, then the security of the wireless bridge as the main transmission channel of the wireless monitoring system It becomes especially important. How to ensure the safety of wireless bridges is an important issue that we need to discuss.
