A coil spring is a spring that is made out of a wire that has been coiled into a spiral. Coil springs are used in many applications, including automotive leaf springs, which are used in vehicle suspensions to support vehicle weight and absorb shocks from the road. Here are the different types of wholesale coil springs:
Compression coil springs
Wholesale compression springs are perhaps the most common type of coil springs. They are used in a lot of applications, from household items like pens to industrial machinery. Compression springs are tightly wound and look like a coiled telephone wire. They are designed to resist axial compressive forces. This means that when a load is applied to the spring, it compresses, and when the load is removed, the spring expands to its original length. It is this ability to maintain its length that makes compression coil springs ideal for applications where space is limited and where constant force is required.
Tension springs
Tension springs are the opposite of compression springs. They are wound in a looser fashion compared to compression springs. Tension springs consist of coils that are close together, and the spring body is usually uncoiled. Tension springs are used to resist tensile forces, and they pull components together. Unlike compression springs, tension springs do not have a defined free length. They are used in applications where a pushing force is required, such as in sliding doors, medical devices, and automotive applications.
Wholesale bushing springs
Bushing springs are not very common, but they are used in specific applications. They are usually found in automotive parts, particularly in the suspension system. Bushing springs help to absorb shock, reduce noise, and improve overall driving comfort. A coil bushing spring is made out of several coils that are wound loosely to create a cylindrical shape. The coils are not uniformly spaced, and the spring has a larger diameter than the original coil. The coils are fitted over a rod or pin, and the bushing spring moves radially.
Wholesale garter springs
Garter springs are one of the least common types of coil springs. They are mostly used in high-tech and industrial applications. Garter springs are made out of a flat spring wire that has been coiled into a circular shape. The coils are not tightly wound, and there is a gap between them. Garter springs are used in applications where a radial force is required, such as in sealing applications, medical devices, and in retaining components.
Double-acting coil springs
Double-acting springs are a combination of compression and tension springs. They are coiled in a way that they can work in both ways. The coils are wound in a way that they alternately touch and overlap each other. When a force is applied, the coils either compress or expand. Double-acting springs are ideal for applications where space is limited, such as in automotive and industrial applications.
Wholesale coil spring manufacturers use specific measurements to make their products suitable for various industrial applications. Here are the specifications of a general coil spring:
Wire Diameter
This is the size of the wire used to make the coil spring. It is measured in inches or millimeters. For instance, a spring might have a wire diameter of 0.5 inches or 12.7 mm.
Outside Diameter
The outside diameter is the total width of the coil spring. This measurement is also done in inches and millimeters. For example, a spring could have an outside diameter of 6 inches or 152.4 mm.
Number of Coils
The number of coils refers to how many times the wire loops around the spring. This figure commonly affects how the spring behaves. A spring could have anywhere from 10 to 100 or more coils.
Material
Wholesale coil springs are made from different materials based on their application. Commonly, they are made from steel. A specific type of steel called spring steel is often used because it is very strong and can bend without breaking.
Heat Treatment
Heat treatment is a process that makes the coil springs stronger. The springs are heated to a high temperature and then cooled quickly. This treatment changes the structure of the steel to make it tougher.
Spring Length
The length of the coil spring when it is not being pulled or pushed is also an important specification. For instance, a spring may have a length of 10 inches or 254 mm.
Load Capacity
This is how much weight the spring can hold without losing its shape. Load capacity is measured in pounds or kilograms. For example, a spring might have a load capacity of 100 lbs or 450 N.
Spring Constant
The spring constant is a measure of how stiff the spring is. It shows how much the spring stretches when weight is added. The spring constant is given in pounds per inch or newtons per millimeter. For example, a spring constant might be 50 lbs/in or 8.8 N/mm.
Wholesale coil spring users need to ensure proper maintenance of the springs so that they can last longer and work efficiently. Here are some tips on how to maintain coil springs:
Regular Inspection
Users should routinely check the coil springs for signs of wear. They should also look for rust, cracks, and other damage to the springs.
Keep it Clean
The coil springs should be kept clean. Dirt and dust that sit on the springs can cause them to wear out quickly. Users can clean the springs with a cloth or brush.
Lubrication
Coil springs should be lubricated with the right lubricant. This keeps them smooth and prevents them from squeaking. Coil spring users should follow the manufacturer's instructions when applying lubricant.
Proper Installation
It is important to install the coil springs correctly. Improper installation can cause the springs to be damaged or not work as they should. Users should follow the instructions from the spring's manufacturer when installing.
Avoid Overloading
Overloading happens when too much weight is put on the coil springs. This can make the springs stretch or be damaged. Users should only load the springs with the weight that they are designed to carry.
Replace Worn Springs
If a coil spring becomes worn out, it should be replaced right away. Using worn springs can cause problems and may damage other parts of the equipment or vehicle.
A number of coil spring factors should be studied before any business purchase. They include the following:
Business buyers should consider the intended use of the coil spring. What load does it have to carry? What weight will it need to support? The answers to these questions will inform the spring choice.
Temperature considerations are also important. Some wholesale coil springs are designed to handle high-temperature environments, while others are not. The spring chosen should be able to withstand the temperature of the environment in which it will be used.
Coil springs come in different sizes. It is important to choose the right size for the intended application. When choosing a spring, buyers should consider its length, wire diameter, and coil diameter.
Buyers should also consider the material used to make the coil spring. Different materials offer different levels of durability and resistance to corrosion. The chosen spring should be made from a material that is suitable for the intended application.
Another important factor to consider is the load capacity of the spring. It should be able to handle the weight of the item it is supporting without becoming damaged or deformed.
Wholesale coil springs are designed for different applications. Buyers should ensure they choose a spring that is suitable for the intended use. For example, some springs are designed for automotive use while others are meant for industrial applications.
Customizations such as surface treatment, spring end, and packing can help buyers meet their customers' needs. They can also help buyers get the right coil spring for the intended application.
Ultimately, the choice of a coil spring should depend on business customers's budget. Different springs come at different price points, so it is important to choose one that is affordable while still meeting the necessary requirements.
Replacing coil springs can be a challenging task, but with the right tools and knowledge, it can be done. First, gather the necessary tools, including a jack, jack stands, coil spring compressors, wrenches, and sockets. It's essential to prioritize safety and work on a level surface.
Start by lifting the vehicle with the jack and securing it with jack stands. Remove the wheels to access the coil springs easily. A coil spring compressor is used to relieve tension on the strut assembly. Follow the manufacturer's instructions for using the compressor safely.
Once the tension is relieved, disconnect the strut assembly from the wheel hub and lower control arm. The old coil springs can now be removed and replaced with new ones. After installing the new coil springs, reconnect the strut assembly and ensure everything is properly tightened. Repeat the process on the other side of the vehicle for even handling.
Finally, reinstall the wheels, lower the vehicle, and remove the jack stands. It's crucial to have the vehicle's alignment checked after replacing the coil springs to ensure proper handling and tire wear.
