About This Product

A power transmission component that transmits the power and motion of the drive shaft to the driven shaft, and at the same time absorbs misalignment and other factors that degrade equipment performance (vibration, noise, minute current, etc.)

■Standard inner diameter

・H7 is recommended for the tolerance of the axis used. ・Non-standard inner diameter and special tolerances can be applied ・Keyway processing available (*Some products are not compatible) ・Clamp separation is possible (*Some products are not compatible)

■Shaft slip torque

- If the shaft slip torque is smaller than the maximum torque of the coupling, compare the shaft slip torque with the actually applied torque (check the motor specifications and load factor). - If the shaft slip torque is smaller than the actual torque used, we recommend increasing the size of the coupling or using a key for safety. ・We recommend that you test the product under the same conditions as the actual usage conditions before use. *Other model numbers are available.
