What is the best compression range?

The optimal compression rate is 15%-25% of free height to ensure the best damping effect.

Do you provide batch matching service?

Yes. We can support full set matching and customized solution service for different vibrating screen models.

Key features

Wet Working Adaptability. Special formula withstands moisture and mineral slurry. It maintains elasticity in high humidity screening workshops.

Dust Environment Reliability. Rubber surface resists abrasive dust accumulation. It keeps smooth elastic action in dusty quarry operations.

Superior Damping Effect. Large internal damping absorbs screen vibration energy. It reduces transmitted shock to supporting structure.

High Resilience Output. The material returns fast after every compression stroke. It supports steady and continuous screen screening motion.

Mining Grade Durability. Components are engineered for heavy mine operation. They last longer than ordinary industrial rubber buffers.

Multi Function Cushioning. It handles vertical compression and horizontal swing loads. It provides comprehensive protection for screen box.

Low Cost Maintenance. It avoids regular lubrication and anti corrosion treatment. It reduces both labor cost and maintenance downtime.

Impact Absorption Capacity. It softens sudden impact from feed material falling. It prevents premature damage of screen main body.

Customizable Design Service. We produce custom sizes and hardness per drawing. It matches special vibrating screen installation requirements.

Stable Batch Quality. Finished products are inspected one by one before packing. It guarantees reliable performance for every shipment.

Product Q&A

Q:What is the advantage of rubber spring compared with steel spring?

Rubber springs support multi-directional shock absorption with lower noise and shorter resonance time, ideal for low-noise and stable operation scenarios.

Q:Is your rubber spring resistant to wet mine slurry?

Yes. Upgraded rubber formula resists slurry corrosion and aging, suitable for long-term use in coal washing and wet screening environments.

Q:Can you adjust the hardness of rubber springs?

We can customize different Shore hardness according to customer load requirements to match different vibrating screens.

Q:What is the service life of rubber springs?

Normally 0.5-2 years depending on working conditions, with better durability than ordinary market products.

Q:Will the rubber spring deform easily?

It features stable elastic recovery and uniform stress, not easy to permanent deform under standard compression range.
