Turn to pages 90 and 91 for Flexible Coupling details.For quick selection of Flexible Couplings, refer to the chart above.Pulleys, Sprockets, GearsThese can be attached to the clutch for off set shaft applications. Tapped holes areprovided for ease of mounting. Nexen does not furnish these items.For minimum sprocket requirements, see page 369.CAUTION!Tooth clutches are normally engaged when stationary. They are not intended for usein most cyclic applications or high speed engagement. In certain circumstances,tooth clutches can be engaged at differential speeds. Please consult Nexen if you areconsidering an application involving engagement at differential speeds.◗ TORQUE VS.
