    FAQs

    We understand that selecting the right clamp half couplings, adaptors, and bobbins can be a complex process, and you may have questions or concerns. Explore our comprehensive FAQ section, where we address common queries and provide insights to help you make an informed decision.

    1. What is the maximum torque rating for steel half couplings?

    The maximum torque rating for steel half couplings varies depending on the specific type and size of the coupling. Typically, steel half couplings can handle torque ratings ranging from 100 Nm to 10,000 Nm (72 lb-ft to 7,400 lb-ft). For specific torque ratings, it is recommended to consult the manufacturer’s specifications or consult with a mechanical engineer.

    2. Can adaptors be customised to fit specific gearbox models?

    Yes, adaptors can be customised to fit specific gearbox models. Adaptors are designed to be machined to fit the output flange of a specific gearbox model. This customisation ensures a secure and reliable connection between the coupling and the gearbox. For customisation, it is recommended to provide the gearbox model number and specifications to the manufacturer or a mechanical engineer.

    3. What is the typical length range for bobbins used in steel half couplings?

    The typical length range for bobbins used in steel half couplings varies depending on the specific application. Typically, bobbins can be extended to lengths ranging from 50 mm to 500 mm (2 inches to 20 inches). For specific length requirements, it is recommended to consult the manufacturer’s specifications or consult with a mechanical engineer.
