Everyone has doors and windows at home, doors and windows have a ventilation effect, but doors and windows also have security risks. In order to give children more security, the quality of doors and windows is particularly important. Personally, the aluminum alloy windows are not bad. So, here for everyone to share broken bridge aluminum windows What are the advantages and how to distinguish quality of aluminum doors and windows broken bridge.
First, what are the advantages of broken aluminum alloy window
1. The aluminum alloy window of the broken bridge is a leather pad between the two aluminum alloys, which has the effect of heat insulation and sound insulation. The thickness of the broken aluminum alloy is 50, 65, 75, etc. The thicker the thickness, the higher the price, the quality. The better.
2, the aluminum alloy window of the broken bridge has many kinds of colors, such as color, imitation wood grain, etc. Of course, the price is also different.
3. The sealing of the aluminum alloy window of the broken bridge is very important. The large-scale machinery or the broken bridge window of the big brand is very smooth at the four corners. If the small factory processes it, the processing of the four corners is relatively poor. The price is definitely cheaper.
4. The glass of the broken bridge aluminum is also very important. It is necessary to select double-layer tempered glass with 3C strength certification. The larger the hollow width of the tempered glass, the better the sound insulation effect.
5. When installing the aluminum alloy window of the broken bridge, the rubber on both sides of the joint between the window and the wall should be evenly glued, and there should be no gaps. If there is a gap, it will be easy to return to the tide for a long time, and the heat insulation effect is not so good.
6, the hardware of the broken bridge aluminum should choose a relatively good brand, try to use the hardware inside the inner opening, so that the rain can also open the window to prevent the rain into the house.
Second, how to distinguish the quality of aluminum alloy doors and windows
1, look at the quality of profiles
First, look at the treatment method used on the surface. If it is an ordinary oxidized profile, you can check the thickness of the oxide film first. The thickness of the oxide film is above 10μm. The oxide film has wear resistance, weather resistance and corrosion resistance, and can be formed on the surface of the substrate. A lot of colors. If it is other surface treatment profiles, it is also necessary to test whether the alkali resistance, acid resistance, abrasion resistance and weather resistance are good; whether the surface of the profile is smooth and the color is consistent.
2, look at the profile angle
Pay attention to the accuracy of the geometry of the profile, the profile can not be bent and twisted, the angle should be very correct.
3, see the thickness of the profile, etc.
It is necessary to carefully check whether the thickness, purity, hardness, toughness and pressure resistance of the profile meet the requirements, and whether the surface of the profile has a squeezing pattern. It is important to check the thickness. Some counterfeit goods use thinner aluminum profiles to make doors and windows, which is not safe.
4, see the profile insulation strip
Pay attention to whether the insulation strip is imported or domestically produced, and you need to ask the merchant for quality inspection report to check. Today, the domestic strips used in China are mainly pvc; the imported heat insulation strips are mainly composed of polyamide added reinforced glass fiber, which is resistant to high temperatures.
Editor's summary: What are the advantages of broken aluminum alloy windows , and how to distinguish the quality of broken aluminum alloy doors and windows, Xiaobian introduced here, I hope to give you help. Pick a good door and window, give your child a safe home, and have more care.

Spherical Roller Bearings are most suitable option for applications that need shock resistant components yet this is not the only quality these Bearings have. These Bearings can handle heavy loads because of their rings` alignment. Due to the curved outer ring, Spherical Bearings come with self aligning capabilities that make it possible to absorb shocks and also enable the apparatus to carry high axial and radial load even in harsh environment with lot of vibration. Even with this rugged working environment, Roller Bearings tend to have high precision.
DESIGN
Spherical Bearings have two rows of rollers that are separated by a cage or rib that could be sealed or unsealed depending on the specific model and application, external raceway and dual raceways in inner ring to support rotating shaft. Amazingly the quality and alignment of raceways, cages and rings define the overall performance and quality of the product. Asymmetrical rollers increase performance and precision while symmetrical rollers offer better load distribution, lesser vibration that ultimately leads to durability.
MATERIAL
These Bearings are manufactured with several kind of material based on the application and working environment. Chrome steel is one of the most popular materials used in production of these Bearings because of its durability yet sheet steel, polyamide and brass are also used for some applications. One of the most important parts of Spherical Bearings is the cage that holds bearings at their place. That cage is usually manufactured with pressed steel or brass because both of these materials offer strength as well as temperature resistance.
These Bearings tend to have seals in order to prevent contaminants like dirt, liquid, debris as well as harsh temperature. This type of these bearing doesn`t even need lubrication if they do not exceed 50% of their maximum allowed RPM.
APPLICATIONS
Spherical Bearings are essential part of heavy machines like gearboxes, turbines, mechanical fans, constructions equipment, mining equipment and drilling equipment. Roller Bearings are available in multiple standard sizes and dimension yet they are also made with custom sizes and specifications.

MODELS AND VARIATIONS
Usually these Bearings come in two different types that have totally different design, structure, specifications and applications.
Single Row Spherical Roller Bearings
These are also known as Barrel Bearings because of their design and they are widely used where only low radial load carrying capacity is required. Other than the load capacity difference, Single Row these Bearings is quite similar to their counterpart in terms of performance and durability.
Double Row Spherical Roller Bearings
These are used where high radial load carrying capacity if required and that make them an essential part of almost all heavy duty machinery out there. The design difference between these two is obvious; Double Row Roller Bearings come with central flanges that optimize the overall performance of the apparatus.
