Excellent Anti Fatigue Property
Precise heat treatment stabilizes the spring internal metallographic structure. It resists fatigue fracture under repeated high frequency vibration.
High Strength Construction
The 60Si2Mn alloy steel provides high tensile strength. It copes with instant heavy impact from mining screening machines.
Adapt to High Frequency Vibration
It maintains stable elasticity under long time cyclic vibration. It prevents early failure for continuous production lines.
Anti Rust Surface Protection
Sandblasting plus anti rust paint prevents surface oxidation. It suits humid dusty mining and aggregate processing sites.
Rigorous Pre Delivery Fatigue Test
Every finished spring undergoes 24 hour continuous operation test. We check amplitude load and temperature for reliable quality.
Customizable Stiffness and Size
We adjust spring stiffness and dimensions for different tonnage vibrating screens. Our technical team offers professional selection advice.
Reduce Equipment Vibration Damage
It buffers vibration energy and disperses structural pressure. It protects screen exciter bearings and other fragile spare parts.
Standard Stock Available
Common specifications are kept in our warehouse for quick shipment. Custom orders take 7 to 12 working days for production.
Low Deformation Rate
Deformation attenuation stays below five percent after repeated compression. It keeps consistent damping performance through its service life.
Wide Industrial Application
It fits linear screens dewatering screens and mineral grading screens. It works for mine quarry sand and coal washing projects.

Product Q&A
Q:What are the main applications of vibrating screen steel springs?
A:
Steel springs are mainly used for heavy-load vibration buffering of mining vibrating screens, suitable for high-strength impact working conditions such as mine screening and coal washing.
Q:What is the service life of your steel springs?
A:
Under standard working conditions, the service life can reach 1-3 years. Strict factory fatigue testing ensures stable long-term operation.
Q:Can steel springs work in humid mining environments?
A:
Yes. The surface is treated with anti-rust paint and sandblasting, which effectively prevents oxidation and corrosion in humid and dusty sites.
Q:Can you customize steel spring sizes?
A:
We support non-standard customization of outer diameter, inner diameter and height according to customer equipment parameters.
Q:What is your steel spring's biggest advantage?
A:
Stable heat treatment performance and excellent anti-fatigue ability avoid frequent breakage and reduce production downtime.
