Keys are customer furnished.Operating Speed: Disengaging speeds are limited to the maximum allowable feet per minute rating of therotary seal between the drive flange and drive ring. Torque Limiters are engaged when stationary.NOTE: For higher speeds-consult Nexen.◗ ATTACHMENT OPTIONSFlexible Coupling AssembliesFlexible Coupling Assemblies are required for in-line coupling applications, and areavailable in single or double flex designs to provide high misalignment capabilitieswith high torque. Turn to pages 118 and 119 for Flexible Coupling details.Pulleys, Sprockets, GearsThese can be attached to the clutch for offset shaft applications. Tapped holes areprovided for ease of mounting. Nexen does not furnish these items.
