Spring leaf or rubber isolator for vibration damping in industrial machinery

Component Specifications

Definition
A vibration isolation component designed to absorb and dissipate mechanical vibrations in machinery, utilizing either spring leaf (metallic) or rubber (elastomeric) elements to decouple vibrating equipment from its supporting structure, thereby reducing transmitted forces, noise, and structural fatigue.
Working Principle
Operates on the principle of mechanical impedance mismatch and energy dissipation. Spring leaf isolators use elastic deformation of metal springs to store and release vibrational energy, while rubber isolators rely on viscoelastic properties of elastomers to convert kinetic energy into heat through hysteresis damping, effectively isolating frequencies above their natural resonance.
Materials
Spring leaf: High-carbon steel (e.g., SAE 1075) or stainless steel (AISI 304/316); Rubber: Natural rubber (NR), neoprene, nitrile (NBR), or silicone compounds with Shore A hardness 40-80, often reinforced with carbon black or fiber.
Technical Parameters
  • Damping Ratio 0.05-0.20
  • Load Capacity 50-5000 kg
  • Natural Frequency 5-25 Hz
  • Static Deflection 5-50 mm
  • Temperature Range -40°C to +120°C
  • Environmental Resistance Oil, water, UV (for rubber types)
Standards
ISO 2017, ISO 10846, DIN 45673, DIN 53504

Frequently Asked Questions

What is the difference between spring leaf and rubber isolators?

Spring leaf isolators offer higher load capacity and durability for heavy machinery, with better performance at low frequencies. Rubber isolators provide superior damping across broader frequencies, are resistant to corrosion, and are quieter, but have lower load limits and can degrade with oils or UV exposure.

How do I select the right isolator for my machine?

Consider machine weight, vibration frequency, environmental conditions (temperature, chemicals), required isolation efficiency, and space constraints. Spring types suit heavy, low-frequency applications; rubber types are ideal for moderate loads and harsh environments where damping is critical.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
