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. Parts DSS10 and DSS12 have one set screw on each end. DSS16, DSS21, DSS26, DSS32 and DSS36 have two set screws 90° apart.
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. Stainless steel hubs available upon request.
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.
