Automatic Sliding Doors can either be a single door sliding in one direction or bi-parting doors where each door leaf slides in the opposite direction. They are often used in grocery stores, entrances to shopping malls, hospitals and other applications where you want to provide your customers a hands free, safe and easy access to your building.
Hospitals
Airports
Retail centers
Pharmacies
Hotels
Grocery stores
Hardware stores
Sporting goods stores
And more
In addition, one of the biggest benefits of automatic doors is energy savings. Since these doors only open when someone comes in or out of your building, it prevents the loss of energy when a door may otherwise be left open for a long time.
Hongfa will only dispatch highly trained CE Certified inspector/technicians to inspect, repair, service or replace automatic doors. This ensures we provide the most efficient and safest door repair for your business.

High-speed bearings are suitable for high-speed bearings. The material has a common aspect. When the dmn value is small, the damage of the bearing can be caused by the fatigue of the surface layer or the subsurface. When the dmn value exceeds 2.5 million, the fatigue layer cracks in the depth. Carry out; when the inner ring is severe, the inner ring will fall off. For this; the outer hardened steel with high external strength and high internal resistance can be used to make the ferrule. Typical such steel materials are AISI8620, CBS600, CBSl000M and VASCOX 2. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
High-speed bearings are sometimes used because of their high temperature or in high-temperature environments; however, they are different from the requirements for general high-temperature conditions. For example, for high-speed bearings operating at 220 ° C; demand is 315 ° C High-temperature data; this is because high-speed bearings require higher high-temperature hardness; to resist the deformation trend caused by high-speed speed effects. High-temperature bearings commonly used in high-speed bearings are M50, M2, WB49 and M315; M50 steel which is remelted by vacuum arc method after method smelting; the life of M50 steel smelted by vacuum induction method is more than 5 times; therefore, it is used more.
Although high-speed bearings do not seem to be in direct contact and corrosion problems, there is a considerable share of high-speed bearings that fail due to data corrosion; in the face of such problems; corrosion-resistant alloys, M50 steels written with chromium ions, and silicon nitride Bearings made of materials such as ceramics.
The cage of high-speed bearings is required to be made of high-strength data. In the case of high demand, AMS 4616 silicon bronze, S-monel alloy, etc. can be used. The most widely used is iron-based alloy AISl4340 (AMS6415); Within the scope of HRC 28 ~ 36. In order to further improve the conflict characteristics of the cage; generally a layer of 20-50μm silver film (such as AMS2412 and 2410) is applied on the outside.
The use of ceramic materials in high-speed bearings is expected to have a larger perspective; during this period, the silicon nitride Si3N4 data has a higher life than the M50 steel; and its specific gravity is only 40% of the steel; it has been used to make rolling bodies and even ferrules; And proved to have outstanding high speed, high temperature adaptability and corrosion resistance; only the current production costs are very high.
