🔧 How RUBASIA Rubbertech’s L-Type Jaw Coupling Works (Ultra Detail)

The L-Type Jaw Coupling is a fail-safe, torsionally flexible, maintenance-free coupling designed to transmit rotational power while absorbing shock, impact load, and equipment misalignment.

1. Two Jaw-Profiled Metal Hubs

Each shaft end is fitted with a metal hub precision-machined with curved “jaws.”
Benefits include:
✔ High torque capacity
✔ Reduced backlash
✔ Strong mechanical interlock
✔ Durable alignment stability

2. One Elastomer Spider Insert

The flexible spider sits between the jaws and acts as the primary vibration absorber.

Spider material options:

• Buna-N (Nitrile Elastomer) – oil resistant, general-purpose
• Urethane (Polyurethane) – high torque, high wear resistance
• Hytrel (High-Performance Thermoplastic) – extreme durability, higher stiffness

3. Torque Transfer Mechanism

As the driving shaft rotates, its hub jaws push against the elastomer spider.
The spider compresses slightly, transferring torque smoothly to the driven hub.

This design ensures:
✔ Low noise operation
✔ Smooth rotation
✔ Shock-load protection
✔ Extended bearing life

4. Misalignment Handling

The spider’s flexibility compensates for:

• Angular misalignment (imperfect shaft angles)
• Parallel misalignment (shafts slightly offset)
• Axial movement (motor vibration or thermal expansion)

5. Fail-Safe Operation

If the spider is worn out or fails, the hubs maintain metal-to-metal contact — meaning:
✔ Machinery keeps running
✔ No sudden downtime
✔ Safe temporary operation

Ideal for remote locations like Kapit, Belaga, Pitas, Tenom, and Lawas where downtime support is limited.
