Notes

Notes

Static Breaking Torque is not recommended operating torque.
Square and hex bore measured across the flats.
Maximum operating angle for transmission of power is 25°.
For greater angular operation, use double universal joint. Join two universal joints back to back and connect with a short shaft. Attach universal joints to shaft by drilling and pinning.
Swing Diameter is the maximum diameter over bearings, clearance must be allowed.
