China Suppliers Factory Friction Springs (Ring Springs) - Compact Energy Absorption Solutions

Introducing our innovative friction springs, designed to deliver exceptional energy absorption and efficient damping solutions. Manufactured in China, our friction springs consist of alternately stacked inner and outer rings, each featuring a conical surface. This unique design allows for optimal frictional force, enabling them to absorb significant amounts of energy through frictional hysteresis. As a leading supplier and factory in the industry, we are committed to providing high-quality friction springs that meet diverse application needs. Enhance your products with our reliable and effective friction springs today!

    Product Details

    Description
    A Spring Brought to Life with the Skills of Our Craftsmen
    For designing friction spring, the calculation formulas published in textbooks cannot be applied as they are in many cases and experience is required.
    We have a track record and expertise related to friction springs that have been built over many years. We not only manufacture friction springs, but we also accept designs according to your request!
    Key Points on Our Devotion Friction Springs
    A large friction spring may see operating loads exceed 100 tons. We confirm and guarantee the friction spring's specifications with a load tester of up to 300 tons.
    We Support Design and Production Even for Small Lots of One or Two Springs
    In the spring industry, our "complete custom-made production & high-mix, low-volume manufacturing" is an extremely unique production system which has not changed since our founding.
    We Guarantee to Deliver the Quantity You Need, When You Need It, at High Quality
    We support all kinds of environments with the likes of heat resistance, corrosion resistance, and durability.
    Springs are very sensitive to high and low temperatures and corrosive atmospheres such as rust. SMS Spring conducts daily verification tests to properly maintain the performance of our springs in any environment such as at temperatures of 100°C or higher, -20°C or lower, as well as for applications in which our springs are exposed to seawater or industrial water!
    🔩
    Custom-Made Expertise
    Years of hands-on experience enable us to design friction springs beyond standard textbook formulas.
    ⚖️
    300-Ton Load Testing
    All large friction springs are verified and guaranteed using our state-of-the-art 300-ton load tester.
    🌡️
    All-Environment Support
    From extreme heat to seawater exposure, our springs are tested daily to perform in every condition.
    Considerations
    📐 Design Guidelines for Friction Springs
    ❑  The inclination angle of the contact surface can be up to 12° in calculation, but it should be noted that depending on the surface finish, the rings may often get caught and not return to their original height.
    ❑  The friction angle changes depending on the surface finish and the lubrication method, and therefore it must be decided in consideration of the manufacturing finish.
    ❑  As a guideline, it is recommended that the plate thickness be 16% to 20% of the outer diameter of the outer ring.
    ❑  It is said that the gap between the rings when no load is applied should be about 25% of the plate thickness.

    💬 Frequently Asked Questions
    Q1 What makes friction springs different from standard springs?
    Friction springs (ring springs) absorb energy through friction generated between the inner and outer rings at their tapered contact surfaces. Unlike standard springs, they can absorb very large amounts of energy in a compact size, making them ideal for heavy-duty applications such as buffer systems and shock absorbers.
    Q2 Can SMS Spring design a friction spring based on my specific requirements?
    Yes. SMS Spring accepts fully custom friction spring designs based on your individual requirements. Our engineers leverage years of accumulated expertise to develop solutions that go beyond standard textbook formulas, ensuring optimal performance for your application.
    Q3 What is the maximum load capacity that can be tested for friction springs?
    SMS Spring is equipped with a load tester capable of testing up to 300 tons. This allows us to verify and guarantee the specifications of even the largest friction springs, which may see operating loads exceeding 100 tons.
    Q4 Is SMS Spring able to produce small quantities, such as one or two friction springs?
    Absolutely. SMS Spring specializes in complete custom-made, high-mix, low-volume manufacturing. We support design and production even for small lots of just one or two springs — a production philosophy that has remained unchanged since our founding.
    Q5 What environmental conditions can SMS Spring's friction springs withstand?
    Our friction springs are designed and tested to perform in a wide range of environments, including high temperatures of 100°C or above, low temperatures of -20°C or below, and corrosive conditions such as exposure to seawater or industrial water. Daily verification tests are conducted to ensure consistent performance across all environments.
    Q6 What should be considered regarding the inclination angle and surface finish of friction springs?
    The inclination angle of the contact surface can be up to 12° in design calculations. However, the friction angle is directly affected by the surface finish and lubrication method, so these factors must be carefully considered during manufacturing. As a guideline, plate thickness should be 16%–20% of the outer ring's outer diameter, and the gap between rings under no load should be approximately 25% of the plate thickness.
