L-Type Jaw Coupling | L-Series Rubber Coupling

Models: L050, L070, L075, L090, L095, L100, L110, L150

RUBASIA RUBBERTECH INDUSTRIES — The Best Rubber Supplier in Malaysia, The Largest Rubber Manufacturer Malaysia, and the Market Leader of Industrial Rubber — offers the Most Advanced, Highest Quality L-Type Jaw Coupling for all industrial applications across Sabah, Sarawak, and Brunei.

Below are Deep, Ultra-Level Product Features engineered for extreme performance.

 

🧩 1. High-Strength Precision-Machined Hubs

• Jaws are machined with tight tolerances for smooth engagement.
• Ensures uniform torque distribution across all spider arms.
• Reduces wear and prevents jaw deformation.
• Available in cast iron, steel, aluminum, depending on application.
• Industrial-grade machining ensures perfect fit for long-term use in harsh Borneo environments.

Benefit: Perfect for vibration-prone industries in Sandakan, Bintulu, Sibu, Kuala Belait, Miri.

 

🕸 2. Advanced Elastomer Spider Design (Premium Grade)

The spider insert is engineered for maximum durability and elasticity.

Options available:

• Buna-N (Nitrile): Oil-resistant for palm oil mills & workshops.
• Urethane: High torque, abrasion-resistant for conveyors & crushers.
• Hytrel: Extreme performance for petrochemical plants in Bintulu & Seria.

Key spider features:

• High damping capability to absorb shock loads.
• Long fatigue life under continuous flexing.
• Multi-lobed design increases contact surface.
• Resists tearing, even under overload conditions.
• Temperature stable — ideal for tropical climates.

Benefit: Protects pump and motor bearings from early failure.

 

🔒 3. Fail-Safe Mechanical Design (Zero Catastrophic Failure)

• Even if the spider fails, hubs maintain metal-to-metal backup contact.
• Machine continues operating until maintenance is performed.
• Eliminates sudden shutdowns and equipment damage.

Benefit: Critical for remote towns like Kapit, Tambunan, Belaga, Pitas where immediate support may not be available.

 

🔄 4. Zero-Lubrication, Zero-Maintenance Operation

• Elastomer spider requires no lubrication.
• No grease contamination on pumps or motors.
• No metal-on-metal wear during normal operation.
• Ideal for dusty or oily industries:
  • Palm oil mills (Lahad Datu, Kunak)
  • Marine industries (Kota Kinabalu, Muara)
  • Timber factories (Sibu, Kapit)

Benefit: Lower maintenance cost, reduced downtime.

 

📏 5. Excellent Misalignment Compensation

The L-Type coupling corrects:

• Angular misalignment
• Parallel misalignment
• Axial shaft movement

The flexible spider absorbs shaft movement caused by:

• Motor base vibration
• Thermal expansion
• Uneven ground installation
• Worn bearings

Benefit: Prevents misalignment-related failures in pumps and compressors.

 

🎯 6. High Torque Transmission Efficiency

• Jaw-to-spider engagement ensures high torque stability.
• Uniform stress distribution minimizes jaw bending stress.
• Elastomer’s elastic modulus optimized for torque shock absorption.
• Suitable for challenging high-load applications like:
  • Hydraulic pumps
  • Blowers
  • Gearboxes
  • Conveyor motors

Benefit: Smooth machine startup and stable continuous operation.

 

🔈 7. Superior Vibration and Noise Reduction

• Spider insert acts as a vibration isolator.
• Reduces motor humming, pump vibration, and resonance frequency.
• Prevents transmission of torsional oscillations.

Benefit: Equipment runs smoother in every Borneo industry — from Sarawak plywood mills to Brunei oil & gas plants.

 

🧱 8. Torsionally Flexible for Shock Absorption

• Perfect for sudden torque spikes during startup.
• Protects shafts and bearings from overload damage.
• Reduces torsional recoil in reciprocating machinery.

Benefit: Extends lifespan of drive systems in:

• Palm oil processing
• Chiller pump systems
• HVAC blowers
• Marine winch motors

 

🔁 9. Fully Interchangeable with Global L-Series Standards

• Matches standard L-Series dimensions.
• Compatible with major coupling brands.
• Easy to replace during emergency breakdowns.

Benefit: Local technicians in towns like Ranau, Beaufort, Limbang, and Tutong can replace quickly without modification.

 

💧 10. Resistant to Oil, Water, Chemical, Dust & Heat

• Hydrophobic elastomer surface resists moisture.
• Chemical-resistant materials suitable for wastewater plants.
• Durable against oil exposure in workshops and mills.
• Heat-stable under tropical temperatures of Sabah, Sarawak, and Brunei.

Benefit: Suitable for harsh coastal industries like Semporna, Kudat, Muara.

 

🏗 11. Lightweight, Compact, and High Strength-to-Size Ratio

• Small overall dimensions.
• Light weight enables easy installation on site.
• Ideal for compact pump/motor locations.

Benefit: Perfect for cramped mechanical rooms in factories, hotels, malls, and vessels.

 

🧮 12. Precision Balancing for Smooth Rotation

• Balanced hubs reduce radial vibration.
• Ensures stable performance at high RPM.

Benefit: Crucial for compressor rooms in Kuching, Miri, Kota Kinabalu.

 

🔒 13. Electrically Non-Conductive (Spider Only)

• Elastomer insert isolates electrical continuity.
• Protects sensitive equipment.

Benefit: Important for marine, chemical, and electrical machinery.

 

🚫 14. No Backlash in Normal Operation

• Spider fits tightly between jaws.
• Eliminates rotational play.
• Ensures accurate movement in precision machinery.

 

🛠 15. Long Service Life

• Wear-resistant elastomer.
• No metallic wear under normal condition.
• Extended durability in dusty palm oil mill environments.
