2. Product Description – Spider Rubber Coupling / Rotex Jaw Coupling

RUBASIA RUBBERTECH’s Spider Coupling is a premium flexible jaw coupling engineered for torque transmission, vibration damping, and misalignment compensation. This coupling consists of:

• Two precision-machined metal hubs (aluminium / cast iron / steel).
• A spider-shaped elastomer insert (PU 92 Shore A / PU 98 Shore A / high-temperature TPU).
• Interlocking curved jaws that ensure fail-safe power transmission.

It is widely used in motors, pumps, blowers, conveyors, compressors, fans, and machining equipment across industrial sectors in Sabah, Sarawak, and Brunei.

3. Key Features (Ultra Detailed)

 High Torque Transmission

Efficiently transfers torque between motor and driven shaft with minimal energy loss.

 Superior Vibration & Shock Absorption

The elastomer spider absorbs torsional vibration—ideal for harsh industrial environments in oil & gas (Miri, Bintulu, Labuan), palm oil mills (Lahad Datu, Sandakan, Miri), and marine operations (Kota Kinabalu, Tawau, Brunei ports).

 Compensates Misalignment

Handles parallel, angular, and axial misalignment, reducing wear on motors and shafts.

 Crowned Jaw Design

Prevents edge pressure caused by misalignment for extended lifespan.

 Maintenance-Free, Long Service Life

No lubrication required; highly durable elastomer spider.

 Fail-Safe Operation

Even if the spider insert fails, the two hubs continue to interlock and transmit torque.

 Customisable Options

• Hub materials: Aluminium, Cast Iron, S45C Steel
• Spider hardness: 92 Shore A, 98 Shore A
• Colours: Red, Yellow, Green, Blue
• Temperature resistance: Standard / High-Temp TPU

4. How Spider Rubber Coupling Works (Simplified Technical Explanation)

1. Two hubs mounted on motor and driven shafts.
2. Concave curved jaws offset around the coupling circumference.
3. Spider elastomer fits tightly between jaws.
4. Under torque, the spider compresses & deflects, absorbing shocks.
5. Misalignment is safely compensated without damaging equipment.

This design ensures quiet operation, reduced downtime, and longer equipment life.

6. Installation / Replacement Guide (Easy Step-by-Step)

Step 1 – Inspect Components

Check hubs, spider insert, shaft conditions, and keyways.

Step 2 – Align the Shafts

Ensure shafts are aligned within tolerance (parallel / angular / axial).

Step 3 – Mount the Hubs

Slide each hub onto the shaft and tighten using key + set screw.

Step 4 – Insert the Spider Element

Place the spider into one hub so every jaw section fits perfectly.

Step 5 – Join the Two Hubs Together

Move the second hub forward until jaws fully engage the spider.

Step 6 – Tighten All Fasteners

Ensure proper torque tightening.

Step 7 – Perform a Rotation Test

Rotate by hand to ensure smooth operation without binding.
