🌏 Engineered for Industrial Power Transmission in Borneo

RUBASIA RUBBERTECH INDUSTRIES proudly supplies the N-Eupex H-Type Rubber Coupling — a flexible, torsionally elastic, and maintenance-free coupling engineered for motors, pumps, compressors, gearboxes, and drive shafts across industrial operations in Sabah, Sarawak, and Brunei Darussalam.

This coupling is widely recognized for its durability, ease of installation, and cost-effective mechanical protection, ensuring smooth power transmission under harsh Borneo conditions — high humidity, heat, and exposure to oil or chemicals.

 

🧩 What is an N-Eupex H Type Rubber Coupling?

The N-Eupex H-Type coupling is a three-piece modular flexible coupling consisting of:

• Two metal hubs (machined for precision fit onto motor and driven shafts)
• An intermediate sleeve (specific to H Type)
• One H-shaped rubber insert (elastomer element) that transmits torque while absorbing misalignment and vibration

The coupling’s torsional elasticity allows it to compensate for:

• Angular misalignment up to 1°
• Radial displacement up to 0.5 mm
• Axial movement due to thermal expansion

The rubber insert acts as both a shock absorber and a vibration isolator, effectively protecting machinery bearings and gear teeth from overload and premature wear.

 

⚙️ Key Engineering Features (Ultra Detail)

1️⃣ High Flexibility in Shaft Alignment

• Compensates for misalignment between motor and driven equipment.
• Minimizes vibration transfer and bearing load.
• Ideal for installations with frequent start-stop cycles (e.g., conveyors, pumps, agitators).

2️⃣ Torsional Vibration Damping

• Absorbs mechanical shocks from sudden torque changes.
• Prevents torsional oscillation in gearbox and motor couplings.
• Reduces dynamic load, enhancing the lifespan of rotating equipment.

3️⃣ Intermediate Sleeve (H Type Advantage)

• Unlike A or B types, the H-type includes an intermediate sleeve for longer shaft distances.
• Allows flexible adaptation between drive and driven shafts without structural modifications.
• Facilitates easy replacement of the rubber insert without moving connected machinery.

4️⃣ Maintenance-Free & Lubrication-Free

• 100% dry coupling — no grease, no oil.
• Routine inspection limited to visual checks on rubber wear.
• Ideal for remote industrial sites such as palm oil mills or offshore platforms.

5️⃣ Premium Rubber Compound

• Formulated using Natural Rubber (NR) and Styrene-Butadiene Rubber (SBR) blend.
• Exhibits excellent resistance to heat, ozone, oil, and tropical humidity.
• Maintains elasticity from -20°C to +80°C operating range.

6️⃣ High Torque Transmission

• Designed for torque ranges up to 16,000 Nm, depending on model size.
• Performs efficiently in both low-speed high-torque and high-speed rotation setups.

7️⃣ Noise Reduction

• The elastomer element significantly dampens mechanical noise —
  a crucial advantage in power plants, workshops, ship engine rooms, and HVAC systems.

8️⃣ Long Service Life

• Resistant to fatigue, mechanical deformation, and cracking.
• Delivers 10+ years lifespan in well-aligned systems under standard load conditions.

9️⃣ Modular Replacement

• Insert can be replaced without disturbing alignment or moving connected shafts —
  saving time, manpower, and alignment cost.

🧰 Installation & Maintenance Guidance (Ultra Technical)

1. Inspect Shaft Ends – Ensure shaft diameters are clean, smooth, and burr-free.
2. Mount Metal Hubs – Fit onto drive and driven shafts using keyway and taper lock.
3. Align Shafts Precisely – Misalignment must not exceed rated tolerances.
4. Insert H-Rubber Element – Position evenly; avoid pinching or twisting.
5. Install Intermediate Sleeve – Bolt securely to maintain uniform torque path.
6. Torque Tightening – Follow manufacturer’s torque table for each model (H80-H480).
7. Post-Installation Check – Run motor at low speed to confirm smooth rotation and no eccentricity.
8. Routine Maintenance – Inspect every 3–6 months for wear, cracks, or deformation. Replace insert if hardness increases or cracks appear.
