2. Complete Technical Description – Spider / Rotex Jaw Coupling
The RUBASIA RUBBERTECH Spider Rubber Coupling is a torsionally flexible elastomeric jaw-type couplingengineered for precision torque delivery, vibration absorption, misalignment handling, and machinery protectionin harsh industrial environments.
It consists of:
1 Two metallic hubs (Aluminium, Cast Iron, or S45C Steel)
Each hub has precisely crowned, concave jaws arranged around a circle.
2 An elastomeric spider
The heart of the coupling—responsible for flexibility and energy absorption.
3 Fail-safe mechanical interlocking
Even if the elastomer fails, the metal hubs still transmit torque at reduced damping.
3. Ultra-Expanded Technical Features (Engineering-Grade)
3.1 Torque Transmission Efficiency
The curved-jaw geometry ensures 100% surface contact between hub jaws and spider segments.
Advantages:
Performance is stable under:
3.2 Torsional Vibration Damping
The elastomer absorbs vibrations generated by:
This reduces:
3.3 Misalignment Compensation – Ultra Detailed
Spider couplings handle:
Parallel misalignment – ±0.2 to ±0.8 mm
Angular misalignment – up to 1° to 2°
Axial (end-float) – ±0.5 to ±1.5 mm
This is critical in Borneo industries where:
3.4 Crowned Jaw Geometry – Deep Engineering Explanation
Traditional straight jaws cause edge pressure → premature spider wear.
RUBASIA’s crowned/jaw design offers:
3.5 Maintenance-Free Operation
No lubrication required.
Elastomer absorbs wear without generating metal debris.
Users benefit from:
3.6 Fail-Safe Safety Feature (Industrial Grade)
If the spider fails due to extreme overload:
Critical for:
3.7 Customisable Options for Harsh Environments
RUBASIA offers:
Hub Materials:
Aluminium – lightweight, corrosion-resistant
Cast Iron – strong, vibration dampening
S45C Steel – high torque, heavy-duty
Spider Hardness:
92 Shore A – high damping
98 Shore A – high torque resistance
High-Temp TPU – heat + chemical resistance
4. Full Technical Breakdown: How the Coupling Works (Advanced Engineering)
4.1 Spider Compression Mechanics
When torque is applied:
This creates:
4.2 Damping Coefficient & Energy Absorption
The elastomer acts as a torsional spring + shock damper, absorbing:
4.3 Thermal Behavior
Spider material resists:
4.4 Misalignment Stress Distribution
The elastomer "floats" between jaws and compensates for:
This prevents:

Tools Required
Step-by-Step Instructions
Step 1 – Prepare the Shafts
Clean using solvent → remove dust, rust, oil films.
Step 2 – Inspect the Hubs & Spider
Check bore tolerance, keyway accuracy, jaw integrity, and spider hardness.
Step 3 – Pre-Align Both Shafts
Use straight edge or laser aligner.
Step 4 – Install Each Hub
Step 5 – Insert the Spider Element
Center each spider lobe into jaw pockets.
Step 6 – Bring Hubs Together
Maintain recommended gap (varies by model, e.g., GR14–GR75).
Step 7 – Perform Alignment Check
Use:
Step 8 – Tighten to Torque Specification
Must follow exact torque chart for set screws and bolts.
Step 9 – Manual Rotation Test
Check for:
Step 10 – 24-Hour Recheck
Recheck alignment after machine warms up.
