About 35mm hot coil spring

Types of 35 mm hot coil spring

35 mm hot coil springs are used in a variety of applications, including automotive suspension systems, machinery, and other load-bearing applications. They are used to store and release energy, absorb shock, and provide a return force. Depending on the application, different types of hot coil springs may be used.

  • 1. Hot wound compression springs:

    Hot-wound compression springs are cylindrical coils of wire that resist compressive forces. They are called ""compression springs"" because they compress under axial loads. They are often used in automotive suspensions to absorb shock and provide a smooth ride. Hot-wound compression springs are also used in various industrial applications, such as textile machinery, printing presses, and packaging equipment.

  • 2. Hot-wound tension springs:

    Hot-wound tension springs are coils of wire that resist tensile forces. They are called ""tension springs"" because they stretch under axial loads. Like compression springs, tension springs are also used in automotive suspensions. Aside from this, they are also used in diverse applications such as office equipment, medical devices, and consumer electronics.

  • 3. Hot-wound torsion springs:

    Hot-wound torsion springs are coils of wire that resist twisting forces. They are called ""torsion springs"" because they store rotational energy. Hot-wound torsion springs are commonly used in applications such as door hinges, valve actuators, and clock mechanisms to provide torque and rotational force.

  • 4. Hot-wound double springs:

    Hot-wound double springs are two springs wound together in opposite directions. They are used in applications that require balanced force distribution, such as in brake systems, clutches, and certain types of automotive suspension systems.

  • 5. Special Hot Winding Springs:

    In some cases, hot-wound springs can be customized to meet specific requirements. This includes adjusting the wire diameter, spring rate, and other parameters to suit the application's needs.

Specification and maintenance of 35mm hot coil spring

The coil springs on 4WD vehicles are constantly working to support the weight of the car and provide a smooth ride over rough terrain. Hot coils that are worn out can cause a number of problems.

Given the level of importance of the 35mm hot coil springs, it is important to understand their specifications and how to maintain them in good shape. Here are some of the key specifications to look out for:

  • Wire Diameter

    The wire diameter of a hot coil spring is an important factor that affects its performance. In most cases, the hot coil spring has a wire diameter of 0.5 inches. Springs with a larger wire diameter are stiffer and can carry more weight. On the other hand, springs with a smaller wire diameter are softer and provide a smoother ride.

  • Spring Length

    The length of the 35mm hot coil spring also affects its performance. Hot coil springs are available in different lengths ranging from 10 inches to 14 inches. Longer springs provide a smoother ride, while shorter springs offer a stiffer ride.

  • Spring Rate

    Spring rate is another important specification of the 35mm hot coil spring. The spring rate is given in pounds per inch (lb/in) and indicates how much the spring compresses when weight is added. The spring rate of the hot coil spring ranges from 200 lb/in to 400 lb/in. Stiffer springs have a higher spring rate and are suitable for carrying heavy loads. Softer springs have a lower spring rate and are ideal for providing a smooth ride.

  • Load Capacity

    The load capacity of the hot coil spring is determined by the wire diameter and spring rate. Most 35mm hot coil springs have a load capacity of 1,000 pounds to 2,000 pounds. When choosing a coil spring, it is important to consider the load capacity. Selecting a spring with a load capacity that is less than the expected load can result in a hot coil 35mm spring that is soft and sagging.

  • Finish

    The finish of a hot coil spring is important for appearance and corrosion resistance. The most common finishes are zinc plating, powder coating, and painting. Zinc plating offers good corrosion resistance, while powder coating provides a durable finish.

With all these specifications in mind, here are some of the maintenance tips to keep the 35mm hot coil spring in good working condition:

  • Regular cleaning: Hot coil springs accumulate dirt and debris, affecting their performance and appearance. Regular cleaning removes the dirt, improving the performance and appearance of the springs. A simple solution of soap and water is effective for cleaning the hot coil springs. Coil springs can also be cleaned using a soft-bristled brush to remove dirt from hard-to-reach areas.
  • Inspecting the coil springs: The next step after cleaning the coil springs is to inspect them for damage. During the inspection, look for signs of wear, cracks, and deformation. Damaged springs should be replaced as they can pose a safety hazard and affect the vehicle's performance.
  • Lubricating the coil springs: Proper lubrication is very important for the smooth operation of the 35mm hot coil springs. Over time, the lubricant on the coil springs wears out, causing the springs to squeak. Lubricate the spring with a silicone-based lubricant to stop the squeaking.
  • Retaining ring: The retaining ring should be checked to see whether it is loose or damaged. If loose, the retaining ring should be replaced. The retaining ring keeps the coil springs in place.
  • Spring compressor: A spring compressor is used to remove and install coil springs. The spring compressor should be checked for proper operation before using it on the coil springs.

How to Choose 35mm Hot Coil Spring

Choosing the right hot coil springs for a particular vehicle can be a difficult task. Here are some tips and considerations to take into account when choosing the proper 35mm hot coil spring.

  • Consider the Vehicle Specifications: When choosing a hot coil spring, the first step is to consider the vehicle specifications. This includes the car make, model, and year of manufacture. This is important, especially because vehicles have different spring sizes. Therefore, choosing a spring that supports the vehicle specifications is crucial.
  • Consider the Vehicle Usage: Coil springs are designed with different spring rates. Some springs have a higher spring rate than others. Coil springs with higher spring rates are suitable for heavy-duty vehicles or vehicles that carry heavy loads. On the other side, vehicles that use coil springs for light-duty applications can use hot coils with lower spring rates.
  • Check the Coil Spring Specifications: Before buying a coil spring, it is important to check the coil spring specifications. This includes the spring size, length, and diameter. The spring size and diameter should match the vehicle's compatible specifications. Also, the coil spring should be compatible with the 35mm suspension system.
  • Consider the Material: Coil springs are manufactured from different materials. The most common material used to manufacture coil springs is steel. Steel is preferred because of its durability and strength. Coil springs made from steel are long-lasting and can withstand heavy loads.
  • Determine the Lift Height: Hot coil springs are designed to increase the lift height of a vehicle. Depending on how much the user wants the vehicle to lift, a suitable coil spring is chosen. Coil springs with a higher lift height are suitable for off-road applications.
  • Consult a Professional: If unsure about which coil spring to choose, it is advisable to consult a professional mechanic. A professional mechanic will recommend the best coil spring suitable for the vehicle.
