RB144 Complete Pin & Bush Flexible Coupling
The RB144 Complete Coupling is a high-capacity, heavy-duty flexible pin and bush coupling engineered to absorb high shock loads, accommodate structural misalignments, and dampen severe torsional vibrations. To fit your machinery seamlessly, please view our In-House Machining Services for precision custom boring and keying options.
Key Features & Advantages
- High Shock & Vibration Absorption: Resilient elastomeric bushes absorb severe impacts, making it ideal for rotating machinery under fluctuating loads.
- Fail-Safe Operational Continuity: Even in the unlikely event of unexpected bush wear, the high-tensile steel pins safely maintain driven connectivity to prevent sudden system dropouts.
- Simplified Maintenances: Designed for easy pin and barrel-bush replacement without necessitating complete hub disassembly or equipment realignment.
- Bi-directional Operation: Smooth power delivery across both forward and reverse rotations.
