When driving and driven shafts are widely separated, an unsupported or floating shaft is used to the span the gap. The two couplings required at each end of that shaft consist of one half of a standard coupling bolted to a Rigid Hub, each unit called a F
features
Large bore capacity with o-ring seal design. The most economical gear coupling design.
Curved face teeth (sizes 1 through 7) for up to 1.5 degrees static misalignment capability.
Series H coupling sleeves will bolt to all competitor couplings sizes 1 through 7 for interchangability in flex halves.
Precision-drilled flange bolt holes with special body-fitting, grade 5 bolts for a long-lasting piloted flange connection.
