Spring buffer rubber

Types of spring buffer rubber

A spring buffer rubber is designed to absorb shock and reduce noise. It is used in various applications like automobiles, construction, and machinery. There are three main types of spring buffer rubbers, as discussed below.

• Natural rubber buffers

  This buffer is made from rubber tree sap. It is strong and flexible, making it a good choice for heavy-duty work. Natural rubber buffers last a long time and can handle tough jobs without falling apart. They also reduce noise and vibrations well. People often use them in places where stopping is important, like on machines or in vehicles. The only downside of natural buffers is that they are not good with heat, oil, or gasoline. If exposed to these elements, they will break down over time.

• SBR buffers

  SBR buffers are synthetic buffers made from styrene and butadiene. They are similar to natural rubber in look and feel. SBR buffers are strong and can last longer than natural rubber in some situations. They also cost less to make. Because SBR is made by scientists, it can be tailored for specific needs. For example, it can be made more heat-resistant or better at stopping oil than natural rubber. The downsides of SBR buffers are that they do not have the same flexibility as natural rubber. This makes them a poor choice for applications where stretching is important. Also, SBR buffers do not handle high temperatures or ozone well.

• EPDM rubber buffers

  EPDM is another type of synthetic rubber. It is made from ethylene, propylene, and diene monomer. EPDM buffers are very good at withstanding heat, cold, and sunlight. This makes them ideal for outdoor use or in places with extreme temperatures. EPDM buffers also resist oils, fats, and chemicals better than natural rubber. This means they will not break down quickly when used in pipelines to transport oil or gasoline. The only downside of EPDM buffers is that they do not have the same tensile strength as natural buffers. Therefore, they are not a good choice for heavy-duty applications.

Specification and maintenance of spring buffer rubber

Manufacturers of spring buffer rubbers provide detailed specifications to help buyers understand the products better. Here are some of the key specifications to look out for:

• Size

  The size of spring buffer rubber varies depending on the model. Buyers can find models with diameters of 50 mm to 80 mm, and lengths range from 100 mm to 200 mm. The size of the buffers required will depend on the specific vehicle make and model.

• Load capacity

  Spring buffer rubbers have different load capacities that range from 1000 kg to 5000 kg. Load capacity refers to the maximum weight the buffer can handle without damage. Exceeding the load capacity can result in premature wear or failure of the buffer.

• Hardness

  The hardness of spring buffer rubber is measured on the Shore A scale. Hardness levels typically range from 60 to 80 Shore A. Buffers with higher hardness levels provide a firmer feel and increased load support, while those with lower levels offer more cushioning.

• Temperature resistance

  Spring buffer rubbers are designed to withstand various temperatures. The temperature resistance is usually between -30°C to 100°C. This ensures the buffers can function in extreme weather conditions without degrading.

• Material

  Natural rubber is the most common material used to make spring buffers. However, some suppliers offer buffers made from EPDM, NBR, and SBR. Each material has its unique properties, such as chemical resistance or durability, which make it suitable for various applications.

Without proper maintenance, the spring buffer rubber can wear out faster, compromising its functionality. Here are some maintenance tips for buyers to pass on to end users:

• Regular inspections

  Users should check the buffers regularly for any signs of wear, damage, or cracking. Early detection of problems can help prevent further damage to the buffers and other suspension system components.

• Keep it clean

  Users should keep the spring buffer rubbers clean to prevent the accumulation of dirt and debris. A clean buffer will have minimal wear, resulting in a longer lifespan. They can use mild soap and water to clean the buffers.

• Proper lubrication

  Spring buffer rubbers require minimal lubrication. Users should apply the right lubricant to the buffers as recommended by the manufacturer. This helps to reduce friction and prevents premature wear.

• Correct installation

  Ensure the spring buffer rubbers are installed correctly according to the manufacturer's instructions. Improper installation can cause uneven wear and reduce the effectiveness of the buffers.

• Replace when necessary

  Users should replace the buffers immediately they notice any signs of wear or damage. Worn-out buffers can lead to more significant issues within the suspension system if not addressed in good time.

How to choose spring buffer rubber

When choosing appropriate spring buffers for specific applications, consider these factors:

• Application Requirements

  Consider the intended function of the buffer in the application. Is it meant for heavy-load support, noise reduction, or impact minimization? Different applications may have varying levels of required cushioning and support.

• Load Capacity

  Determine the maximum load that the buffer will need to support. It should be selected based on the load capacity to prevent premature wear or failure. Choosing a buffer with a load capacity significantly higher than the application load can result in inadequate compression and reduced effectiveness.

• Hardness and Compression

  Select a buffer with hardness and compression characteristics suitable for the application. Harder buffers offer firmer support, while softer ones provide more cushioning. Consider the trade-off between comfort and support in applications like furniture, buffers, and industrial machinery.

• Material Durability

  Consider the durability of the buffer material in the specific environment. Will it be exposed to extreme temperatures, chemicals, or moisture? Choosing buffers made from resilient materials can ensure long-lasting performance and reduce the need for frequent replacements.

• Noise Reduction

  If noise reduction is a crucial factor in the application, prioritize buffers designed with sound-dampening properties. These buffers can minimize vibrations and noise, creating a quieter and more comfortable environment.

• Installation and Maintenance

  Consider the ease of installation and maintenance requirements of the chosen buffers. Some buffers may need specialized tools or expertise for installation, while others offer straightforward and user-friendly installation options. Additionally, consider the maintenance needs, such as cleaning or periodic replacements, to ensure hassle-free operation.

How to DIY and Replace Spring Buffer Rubber

Replacing spring buffers on vehicles can be a simple process that is easy to do with the right tools. Here are some steps to follow.

Tools needed

• Jack and jack stands
• Socket wrench or ratchet
• Torx or hex driver
• Pry bar or large screwdriver
• New spring buffers

Step-by-step guide

• 1. Ensure the vehicle is parked on a flat surface. Engage the parking brakes, and wheel chocks are placed around the wheels, which provides extra stability.
• 2. Use the jack to lift the vehicle and place the jack stands under the vehicle to support it.
• 3. Refer to the vehicle's service manual to locate the spring buffer assembly. The spring buffers are generally found near the vehicle's suspension system.
• 4. Use a socket wrench or ratchet to remove the bolts that hold the spring buffer. A Torx or hex driver may be needed to remove the bolts, depending on the vehicle model.
• 5. A large screwdriver or pry bar can be used to remove the old rubber buffers. The old buffers may be stuck on the spring, making them difficult to remove.
• 6. Place the new rubber spring buffers onto the spring. Ensure they fit snugly and are positioned correctly.
• 7. Use the socket wrench or ratchet to reattach the bolts and tighten them securely.
• 8. Once the buffers have been replaced, remove the jack stands and lower the vehicle using the jack.
