Taper Bore R Coupling
Taper Bore R Couplings combine high-torque capability with the convenience of taper lock bushings, allowing quick installation and removal without machining shaft bores. They transmit power reliably across heavy machinery while accommodating angular misalignment up to 1.5° per gear mesh. Engineers and maintenance teams specify Taper Bore R Couplings to reduce downtime, protect drive systems, and simplify shaft mounting in motor, pump, and gearbox assemblies.

Engineering Notes & Application Guidelines
- Mounting Configuration: We supply standard assemblies with inboard-inboard hubs. Flex hubs or rigid hubs can also accommodate outboard mount bores upon request.
- Misalignment Capacity: Accommodates maximum angular misalignment up to 1.5° per gear mesh. For optimal coupling life and minimal bearing stress, ensure combined angular and offset misalignment does not exceed 0.75° per flex half coupling.
- Custom Sizes: Consult our engineering team at sales@powertrans-tech.com for sizes larger than 80R, special taper bushing bores, or custom torque ratings.
