1. Product Overview – MH Rubber Coil / Hyperflex MH Coupling

The MH Rubber Coil Coupling, also known as Hyperflex MH Coupling, is a torsionally flexible shaft couplingdesigned for the toughest industrial environments. It uses a rubber-in-compression design, where the rubber element—reinforced with strong steel cores—absorbs shock, isolates vibration, and protects critical components from overload.

Standard Model Range:

MH65, MH80, MH90, MH115, MH130, MH145, MH175, MH200

These couplings are widely used across Sabah, Sarawak, and Brunei, especially in remote and industrial-heavy towns such as Sandakan, Bintulu, Miri, Lahad Datu, Kuching, Tawau, and Kuala Belait.

2. Ultra-Detailed Technical Design Description

2.1 Rubber Element Structure

The MH coupling features a high-grade synthetic rubber coil with:

• Core reinforcement using solid steel rods
• Precision-engineered compression grooves
• Anti-shear geometrical design
• High elasticity for torsional flexibility
• Oil-resistant, ozone-resistant, chemical-resistant formulation

The rubber is specially chosen to withstand high humidity, salt air, and palm oil mill environments common across Borneo regions such as Semporna, Beluran, Mukah, Kapit, and Serian.

2.2 Hub & Flange Construction

Each MH coupling uses cast iron or ductile iron hubs, designed with:

• Precision-machined bore
• Keyway and set screws
• Accurate balancing tolerance
• High tensile strength for high torque loads

Many sites in Sabah (e.g., Keningau, Tenom, Ranau) and Sarawak (e.g., Sri Aman, Betong, Lundu) operate heavy-duty machinery requiring robust hub materials — MH couplings provide exactly that.

2.3 Misalignment Tolerance & Compensation

The MH rubber element provides exceptional compensation for:

• Parallel misalignment
• Angular misalignment
• Axial displacement

This is especially important for industries in rugged terrain areas such as Limbang, Long Lama, Belaga, Pitas, Telupid, Sipitang, and Lawas, where machinery foundations may not be perfectly aligned.

2.4 Vibration Isolation & Shock Absorption

The MH rubber coil absorbs:

• Torsional vibration from pumps and compressors
• Sudden shock loads from starting and stopping
• Harmonics generated by motor speed variations

This protects bearings, shafts, seals, and gearboxes — a key requirement for:

• Water pumps in Kuching, Miri, Kota Kinabalu
• Compressor rooms in Sibu, Tawau, Sandakan
• Palm oil mills in Lahad Datu, Bintulu, Kapit

2.5 Temperature & Chemical Resistance

Operating temperature:
–40°C to +100°C

Rubber material withstands:
 Oil, grease, fuel
 Palm oil & hydraulic oil
 Marine saltwater
 Ozone & UV exposure
 Industrial solvents

This makes it suitable for coastal regions such as:
Kudat, Semporna, Kota Belud, Muara, Lumut, Kuala Belait, Sampadi, Bintulu, and Miri.

3. Technical Performance & Advantages

3.1 Torque Transmission Efficiency

MH rubber couplings deliver smooth and efficient torque transfer, minimizing motor load and reducing power loss.

3.2 Excellent Damping Properties

Ideal for noisy pump rooms and mechanical workshops in Sandakan, Kuching, Miri, and Kota Kinabalu.

3.3 Protection for Downstream Equipment

Reduces:

• Bearing failures
• Shaft fatigue
• Gearbox wear
• Seal damage

3.4 Long Service Life

Designed to operate continuously in humid industrial zones like Mukah, Sarikei, and Tawau.

3.5 Zero Lubrication Required

Unlike gear couplings or chain couplings, MH rubber couplings require no lubrication, resulting in lower maintenance costs.
