Specifications and Maintenance of Obk Coil Spring

Specifications of OBK Coil Spring

The specification of OBK coil springs is crucial for ensuring that the spring chosen for the application will perform effectively and reliably. The spring is specified using several measurements.

• Wire diameter:

  This is the thickness of the wire used to make the spring, and it is measured in mm or inches. The diameter affects the spring's strength and its ability to deflect.

• Spring outside diameter:

  The coil spring's diameter is measured from one outside edge to the other outside edge. The outside diameter will affect the amount of space the spring occupies and its compatibility with the spring seat.

• Spring inside diameter:

  The coil spring's diameter is measured from one inside edge to the other inside edge. The inside diameter is important when it comes to determining the fit of the spring on the shock absorber or strut.

• Number of active coils:

  The active coils are the coils that deform when the spring is loaded. They are responsible for the spring's deflection and contribute to its overall spring rate. The number of active coils affects the spring rate and the behavior of the coil spring.

• Coil spring length:

  The spring length is measured when the spring is not loaded. The spring length affects the spring rate and the amount of space the spring occupies.

• Spring rate:

  The spring rate of a coil spring is a measure of the force required to compress the spring by one unit of distance. For example, it measures the force in pounds needed to compress the spring by one inch. The spring rate is an important specification because it determines the behavior of the spring. A spring with a high spring rate will be stiff and resistant to compression. On the other hand, a spring with a low spring rate will be soft and easy to compress.

• Material:

  Coil springs are mostly made from steel, although other materials like composites and alloys can be used. The steel used in making the spring can be treated to improve its mechanical properties.

• End type:

  The type of end used in an OBK coil spring is important for mounting the spring on a vehicle. The ends come in different designs, such as squared, ground, or closed.

Maintaining OBK Coil Spring

Maintaining the OBK coil spring is essential to ensure that it lasts and performs well in applications. Here are some maintenance tips:

• Inspection:

  The coil springs should be regularly inspected. During the inspection, the eyes should look for signs of rust, wear, and damage. The earlier the damage is detected, the easier it can be repaired. Apart from visual inspection, the springs should be physically checked to feel for sagging, broken coils, and uneven gaps between the coils.

• Load rating:

  The coil spring's load rating should not be exceeded. When the load rating is exceeded, the spring becomes damaged quickly, and it can also affect the vehicle's suspension system.

• Lubrication:

  The coil spring should be lubricated. Lubrication helps reduce friction between the coils and prevents wear. When choosing a lubricant, make sure it is compatible with the spring material.

• Cleaning:

  The coil spring should be cleaned regularly. Dirt, sand, and debris can accumulate in the spring and affect its function. When cleaning the spring, use a mild detergent and a soft brush.

How to choose OBK coil spring

Before shopping for coil springs, it is important to understand the target market's needs. Coil springs are used in various applications, including vehicles, lawnmowers, and mattresses. Determine the type of coil spring needed and the application it will be used for. Different OBK coil spring manufacturers offer a variety of coil springs. Make sure to partner with a reliable and reputable supplier who can provide customized springs to fit specific needs. Reach out to the supplier and ask whether they can provide the desired spring specifications.

Choosing the right coil spring for the application is a key factor that affects the performance of the spring and its lifespan. Consider the material of the coil spring wire. Steel is a popular choice for many applications because of its corrosion resistance and strength. OBK coil springs made from stainless steel offer higher strength and corrosion resistance, making them suitable for marine applications. The application will help determine the material of the coil spring to purchase.

Coil springs come in different sizes and dimensions. When choosing the right coil spring, consider the spring length and diameter. The spring size has a great impact on the load capacity and stiffness of the spring. A larger coil spring has a low spring rate and can accommodate more loads compared to a smaller spring. Also, consider the wire diameter. Coil springs with thicker wires are stronger and harder to compress. They have a higher spring rate and can handle larger loads. Thinner springs have a low spring rate and are suitable for applications with lighter loads.

The application and specific needs determine the obk coil spring design. Look for a supplier who can provide customized spring designs based on the requirements. Common coil spring designs include the tension spring, compression spring, and double spring.

Before placing an order, check if the supplier offers a warranty for the coil springs. A quality spring has a long service life and causes less downtime, making it a worthy investment. Some suppliers also offer after-sale services such as free shipping and product returns.
