Lovejoy, Inc. : Products : Couplings & Power Transmission: Universal Joints

Notes:

* Static breaking torque is not a recommended operating torque.
* Square and hex bores are measured across the flats.
Operation of all universal joints is determined by the angle/speed combinations of the application. Consult Lovejoy Engineering for specific limitations and recommendations.
Applications that fall outside the limitations of these tables should be referred Lovejoy Engineering for assistance.
