Rubber Bushing
With over 40 years of experience in the rubber industry, Zong Yih Rubber specializes in rubber-to-metal bonding technology and precision vibration-control components.
Our Rubber Bushings (Full Bonded Type) are one of our core and highly reliable product lines for industrial and automotive applications.
Our rubber isolator bushings integrate rubber and metal sleeves through a stable, high-strength bonding process, providing excellent vibration damping, structural support, noise reduction, and durability under dynamic loads.
Standard Specifications
Rubber Bushing (Full Bonded)
- Elastomer: Natural Rubber (NR)
- Hardness: 55–75 Shore A (adjustable per application)
- Metal Component: Zinc-plated Steel
Features & Functions
- Vibration Absorption
The rubber effectively absorbs vibration and impact energy, reducing vibration transmission during operation and improving system stability. - Noise Reduction
The rubber layer isolates direct metal-to-metal contact, significantly reducing noise and improving operating quality. - Elastic Support & Cushioning
Capable of handling compressive, shear, and torsional loads, the bushing ensures proper elasticity and buffering during dynamic movement. - Enhanced Durability
The full-bonded design provides long-term resistance to repeated loads, preventing debonding and deterioration, making it suitable for high-frequency and high-vibration applications.
How Rubber Bushings Work
A rubber bushing functions as a vibration isolator that absorbs energy through elastic deformation.
When compressive or shear forces are applied, the elastomer deforms and disperses the energy across the bonded interface. This prevents excessive vibration transmission between connected metal components.
The full-bonded rubber-to-metal design enhances stiffness control, energy absorption, and stability, making it ideal for:
- Suspension systems
- Powertrain vibration isolation
- Machinery rotating parts
- Structural damping applications
This combination of elasticity and bonding strength significantly reduces noise, increases system precision, and prolongs equipment lifespan.
