ULTRA-DETAILED PRODUCT FEATURES — SPIDER RUBBER COUPLING / ROTEX COUPLING

RUBASIA RUBBERTECH INDUSTRIES’ Spider Rubber Coupling, also known as Rotex Rubber Coupling, is engineered for high-precision, high-performance torque transmission across demanding industrial environments. Manufactured to international standards, our GR-Series (GR14 to GR75) offers exceptional alignment tolerance, superior shock damping, and long service durability, making it the preferred choice for machinery across Sabah, Sarawak, and Brunei.

 

✅ 1. Advanced Torque Transmission Performance

Our Spider Rubber Coupling ensures high torsional stiffness while maintaining the flexibility needed to protect machinery.
Key torque-related features:

• High torque capacity across all GR models (GR14–GR75)
• Precision-engineered jaws ensure uniform torque distribution
• Zero backlash under normal operation
• Stable performance even in rapid start-stop applications
• Designed for electric motors, gearboxes, pumps, blowers, mixers, conveyors, and compressors

 

✅ 2. Premium Elastomeric “Spider” Element

The heart of the coupling is our high-grade elastomer spider, available in multiple hardness levels.
Material options include:

• PU 92 Shore A (Standard) – Balanced flexibility & damping
• PU 98 Shore A (High torque) – Higher torsional resilience
• TPU Special Grade – Heat-resistant for harsh environments
• Oil-resistant elastomer – For refineries, marine & chemical plants

Benefits:

• Excellent damping of torsional vibration
• Shock load absorption to protect gearbox & motor
• Resistant to wear, chemical splash, and temperature fluctuations
• Silent operation without rattling or vibration noise

 

✅ 3. High-Precision Jaw Hub Design

Each hub is manufactured with curved, crowned jaws that provide smooth engagement and minimise stress concentration.
Hub material options:

• High-strength aluminium
• FCD cast iron
• Carbon steel
• Stainless steel (304/316)

Feature advantages:

• Reduces edge pressure during misalignment
• Ensures maximum spider lifespan
• Prevents backlash and micro-slippage
• Perfect concentricity ensures smooth rotation

 

✅ 4. Outstanding Misalignment Compensation

The Spider Coupling absorbs and compensates for:

• Parallel misalignment
• Angular misalignment
• Axial displacement

This protects connected equipment in applications where:

• Mounting inaccuracies occur
• Shafts expand due to heat
• Machinery foundations shift over time
• Vibration from pumps, blowers, or motors create movement

 

✅ 5. Fail-Safe Design for Critical Industries

Even if the elastomer spider wears out, the hub jaws interlock to continue transmitting torque.

• Zero downtime during spider failure
• Prevents sudden machine shutdown
• Ideal for continuous-operation plants

 

✅ 6. Maintenance-Free, Long Life Durability

RUBASIA’s GR-Series requires no lubrication, no adjustments, and no frequent replacement.
Benefits include:

• Lower maintenance cost
• Fewer stoppages and production losses
• Long service life even under high vibration
• Easy spider replacement without removing hubs
