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 MBS15 and MBS19 have one set screw on each end. MBS25, MBS33, MBS41 and MBS51 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 Our standard couplings are supplied with black anodized aluminum hubs. Stainless steel hubs are available upon request.
