Fingerprint password technology is a major trend in the development of locks. The use of fingerprint locks represents fashion, dignity and atmosphere. Fashion design and generous. As a high-end lock, Fingerprint Lock has European-style, Chinese-style, elegant retro and other styles of appearance, the surface technology also uses a number of gold-plated, copper, chromium and other processes, such as the general fine art. In addition, intelligent anti-peeping and unique virtual password input methods are also popular in the market. 1. Security: The key of an ordinary mechanical lock can be copied. The owner does not trust the owner after use. The fingerprint has uniqueness. There are no two complete fingerprints in the world. 2. Convenience: It is not necessary to carry the key with you and it is the key that will never be lost. A person's fingerprint will not change for the rest of his life. Once the fingerprint is entered, he can use it for his entire life. And one can input fingerprints of different fingers. Touch to open it, unlock it. 3, expandability: can accommodate 199 fingerprints, but you can easily register the input fingerprint, delete the fingerprint, the fingerprint management is very convenient, compared with the ordinary mechanical lock eliminating the need to prepare the key and the key to the annoyance, especially for office use Housing and rental rooms. 4, can set 8 groups of passwords, and have a password to prevent peeping. And fast operation, password can be replaced at any time. 5, long-term maintenance-free: the use of ordinary mechanical lock life is short, and easy to emerge during the application of failure, had to break into the door, and fingerprint locks do not emerge on the basis of failure. 6. The recognition rate is high: the rejection rate is less than 1%, the recognition rate is less than one millionth, and the fingerprint can be correctly compared within 360°. 7, fashion: fingerprint password technology is the direction of lock development, the use of fingerprint password lock represents the fashion, noble, cutting-edge. Fashion design and generous. 1. Some people or some groups have few fingerprint features and are difficult to image. 2. Each time the fingerprint is used, the fingerprint of the user is left on the fingerprint collecting head, and these fingerprint traces are used to copy the fingerprint. 3, password lock stability and durability without a strong mechanical password.

The full ceramic ball bearings listed below are supplied with rings and balls made from zirconium dioxide (ZrO2). These zirconia bearings are available as full complement (no cage) or with cages made from PTFE, PEEK or 316 stainless steel.
These are non magnetic, non-conductive and highly corrosion resistant to most chemicals although ZrO2 bearings are not recommended for prolonged contact with steam. Full complement bearings or those with a 316 stainless cage can be used up to 400°C while bearings with a PEEK or PTFE cage can cope with temperatures of up to 250°C. For temperatures below -70°C, PTFE or 316 stainless steel cages are preferred. Standard radial clearance for full ceramic bearings is C0 but other clearances can be supplied to order.
ZrO2 ceramic bearings are generally used for their extreme temperature capabilities, excellent corrosion resistance or non-magnetic properties. Other sizes can be supplied on request.

Compared to steel, Ceramic ball Bearings have many specific advantages. They offer superior corrosion and heat resistance, higher dimensional stability, and lower density, which facilitate high speed. Ceramics are superior to steel in heat and corrosion resistance, and are lightweight and extremely hard as well. Consequently, ceramic rolling bearings can be used in environments where conventional steel bearings cannot. That is to say, the superiority of these bearings makes it possible that they can be applied in some special environments.
Firstly, they can be used in corrosive environments. Compared to stainless steel bearings, hybrid and all Ceramic Bearing lasted three and twenty times longer respectively. It is presumed that water readily adheres to silicon nitride and forms a better lubrication film, leading to extended bearing life.
Secondly, they can be performed in corrosive agents. Generally, silicon nitride has excellent corrosion resistance. However, corrosion resistance varies depending on the type and quantity of sintering additives, and certain corrosive agents decrease in hardness and flexural strength. In such situation, it is can be proved that the carbide-based ceramic bearings are the most effective.
Thirdly, they can be used in high-temperature vacuum. An all-silicon nitride Ball Bearing with a self-lubricating laminated cage (mainly composed of MoS2) and with MoS2-coated rings and balls proved superior in durability in a high-temperature vacuum environment. Compared with the hybrid bearings, the all-ceramic bearing was superior in both dynamic frictional torque and life.
Fourthly, they can be performed with poor lubrication. As ceramics are extremely hard and have outstanding wear resistance, they outperform other materials in bearing life without lubrication. According to a test, the steel bearing seized within a short period while the hybrid and all 627 Ceramic Bearings, though sustaining wear, did not. And the all-ceramic bearing sustained considerably less wear than the hybrid bearing, indicating that its endurance life is much longer.
