When selecting a coupling, consider factors like torque requirements, as the coupling needs to handle the load without slipping. Misalignment tolerance is important to accommodate any shaft misalignment. You should also assess the operating speed, ensuring the coupling can perform efficiently at the machine's speed. Additionally, consider environmental conditions like temperature, moisture, or exposure to chemicals, and choose a material that can withstand these conditions. Finally, evaluate the maintenance needs and cost-effectiveness to ensure long-term reliability in your application.
