 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:

• Inner Metal Sleeve – Transfers load and provides structural rigidity.
• Bonded Rubber Layer – Elastic section that absorbs vibration and impact energy.
• Outer Metal Sleeve – Holds the bushing firmly inside the housing or bracket.

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:

• Axial movement – Compression or elongation along the axis.
• Radial movement – Sideways deflection for lateral shock absorption.
• Torsional movement – Controlled rotation under twisting force.
• Conical movement – Angled deflection to accommodate misalignment.

This flexibility ensures long-term stability without the need for maintenance or lubrication.

�� Construction & Material Technology

Every RUBASIA bush undergoes precision molding, curing, and hardness testing (Shore A scale) to achieve optimum vibration isolation and load-bearing characteristics.

� Applications of Rubber Bush & Coupling Bush

A. Automotive Applications

RUBASIA Rubber Bushes are integral components in vehicle dynamics systems.
They are widely installed in:

• Suspension Arms (Control Arm Bushes)
• Shock Absorbers (Eye Bushes)
• Anti-roll Bars / Stabilizer Links
• Engine Mounts and Gearbox Supports
• Steering Rack Mounts and Torque Rods

Used by workshops and fleets across Kota Kinabalu, Sandakan, Tawau, Lahad Datu, Keningau, and Kudat, RUBASIA bushes enhance comfort, control, and safety by minimizing vibration and road shock.

B. Industrial Machinery & Equipment

Across Sarawak and Brunei, our bushes protect machinery in:

• Air Compressors
• Diesel Generators
• Industrial Pumps and Blowers
• Mixers and Agitators
• Conveyors and Vibratory Feeders
• CNC Machines and Press Equipment

By reducing vibration and mechanical resonance, RUBASIA bushes extend component life, protect bearings, and prevent structural fatigue in factories at Kuching, Sibu, Bintulu, and Miri.

C. OEM Manufacturing & Engineering

Our OEM coupling bushes are customized for machinery builders, fabrication shops, and plant integrators across Sarikei, Kapit, Limbang, Lawas, and Betong, ensuring perfect alignment and long-term damping for moving parts and couplings.

D. Electronics & Home Appliances

Used in washing machines, dryers, air conditioning units, and electronic control housings, these bushes help reduce noise and vibration in residential and commercial appliances across Bandar Seri Begawan, Kuala Belait, and Tutong.
