ULTRA-DETAILED PRODUCT ENGINEERING DESCRIPTION
The HRC (Highly Resilient Coupling) is a precision-engineered jaw-type flexible coupling designed to deliver smooth torque transmission, vibration isolation, and misalignment tolerance between motor and driven equipment.
It consists of:
1. Precision-Machined Metal Hubs
2. High-Resilience Rubber Spider (Elastomer Element)
3. Fail-Safe Compression Torque Transmission System
Unlike shear-type couplings, the HRC transmits torque under compression, meaning:
ULTRA-DETAILED MECHANICAL PERFORMANCE FEATURES
High Torque Delivery
The elastomer transmits torque uniformly through compression zones, reducing stress on metal components. Suitable for:
Excellent Vibration & Shock Absorption
Reduces:
This is crucial in coastal/humid environments like Kota Kinabalu, Kudat, Semporna, Miri, Brunei-Muara where machinery is prone to corrosion and vibration instability.
Misalignment Capacity
The HRC coupling allows:
It helps compensate for shaft displacement due to:
Electrically Conductive Rubber
Prevents static charge buildup in:
Durable, Oil-Resistant, and Puncture-Proof
Rubber spider resists:
This is particularly important for oil & gas zones in Sarawak (Bintulu, Miri, Bekenu) and Brunei (Seria, Kuala Belait).
EXTREMELY-DETAILED INDUSTRY APPLICATION USE CASES (BORNEO-FOCUSED)
1. Palm Oil Mills (Sabah + Sarawak)
Used in:
HRC couplings reduce vibration from heavy rotating machines, essential in mills located in Sandakan, Lahad Datu, Tawau, Sibu, Saratok, Bintulu.
2. Marine & Offshore (Miri, Labuan, Brunei)
Installed in:
Salt-air corrosion resistance makes it suitable for shipyards in Kota Kinabalu, Miri, Brunei-Muara, Labuan.
3. HVAC & Building Services
Used for:
Large buildings in Kuching, Kota Kinabalu, Bandar Seri Begawan, Miri rely on HRC couplings for vibration suppression.
4. Industrial Manufacturing
Found in:
Installed widely in industrial zones like KKIP, Samalaju Industrial Park, Demak Laut, Seria Industrial Area.
5. Water Treatment Plants
Applications:
Critical in remote towns such as Belaga, Kapit, Ranau, Pitas, Mukah, Limbang.
