Oldham Couplings - Large Shaft Diameter, Set Screw / Clamping / Spacers, Economy series

Operating Temperature: -20°C ~ 80°C ETolerances for d1 and d2 are values before slit machining.
The lateral, angular, and axial misalignment values shown are for each occurring individually.
When multiple misalignments are occurring simultaneously, the allowable maximum value of each will be reduced to 1/2.
