NPX-125 Type B Flexible Coupling (Part 1 and Part 4)
The NPX-125 Type B is a high-performance, flexible shaft coupling designed to deliver reliable power transmission while compensating for structural shaft misalignments. Consisting of Part 1 and Part 4 configurations, this Type B coupling features precision-machined components designed to minimize torsional vibrations, dampen operational shock loads, and maximize the operational lifespan of your drivetrain assemblies.
Key Features
- Torsional Flexibility: Optimizes dampening characteristics to safeguard electric motors and connected gearboxes from sudden load spikes.
- Misalignment Compensation: Effectively absorbs parallel, angular, and axial misalignments during continuous service.
- Fail-Safe Assembly: Interlocking jaw layout keeps the drivetrain safe and structurally operational even under peak overload conditions.
- Type B Configuration: Supplied with Part 1 and Part 4 specifications tailored for standard industrial mounting setups.
