About RUBASIA RUBBERTECH INDUSTRIES
RUBASIA RUBBERTECH INDUSTRIES is recognized as the largest rubber component manufacturer in Malaysiaand the leading supplier of industrial rubber bushes and coupling bushes across Borneo, covering all major and rural industrial hubs in Sabah, Sarawak, and Brunei Darussalam.
We produce high-performance rubber vibration isolators that are engineered for heavy-duty automotive, machinery, and industrial use — ensuring long-lasting performance, safety, and operational stability even under the harsh tropical conditions of East Malaysia.
Our factory uses advanced rubber compounding, precision metal bonding, and vulcanization technologies to ensure every bush offers maximum vibration absorption, torsional flexibility, and dimensional stability.
Product Overview – Rubber Bush & Coupling Bush
A rubber bush (also known as a rubber bushing or coupling bush) is a mechanical vibration isolator designed to absorb impact, reduce vibration, and eliminate metal-to-metal contact between machine components.
Each RUBASIA bush consists of:
This unique rubber-to-metal bonding system creates a durable joint capable of absorbing multidirectional movement — axial, radial, torsional, and conical — without lubrication or excessive wear.
Detailed Working Principle of Rubber Bush
1. Vibration Absorption
When machinery or vehicles experience vibration, the rubber bush deforms elastically.
This deformation absorbs kinetic energy from the vibration source and prevents it from transferring directly to other components such as chassis, suspension arms, or motor mounts.
2. Shock Energy Dissipation
Under sudden impact (e.g. road bumps, engine torque), the rubber layer acts as a cushion, dissipating shock energythrough elastic deformation. This significantly reduces mechanical fatigue and extends equipment lifespan.
3. Noise, Vibration & Harshness (NVH) Reduction
Internal molecular friction within the rubber converts vibration energy into minor heat energy, effectively reducing audible noise and vibration harshness, resulting in quieter machine operation and smoother vehicle performance.
4. Isolation and Damping
The rubber acts as a vibration barrier, isolating two rigid parts and preventing the transmission of high-frequency mechanical vibration and resonance across structures.
5. Controlled Multi-Axis Movement
The design of RUBASIA coupling bushes allows controlled deflection in multiple axes:
This flexibility ensures long-term stability without the need for maintenance or lubrication.
