Note 1 Static torque ratings are at maximum misalignment. To obtain dynamic rating, static ratings should be divided by 2 for non-reversing applications and by 4 for reversing applications.
Note 2 Hardware is alloy steel with black oxide finish.
Note 3 Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 4 Ratings are for standard couplings supplied with black anodized aluminum hubs and center spacers. Stainless steel hubs and center spacers available upon request. Insulating (Acetal) spacers available with our DCDE series.
Note 5 Torque ratings for the couplings are based on the physical limitations/failure point of the disc springs. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the disc springs. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance.
Note * Shaft can only be insterted into hub upto LH dimension.
