Deltaflex Round Hubs without Keyway - Inch (Imperial) Bores

Check up to five results to perform an action.

The patented Deltaflex series of couplings offer maximum misalignment capabilities with negligible reactionary load, for longer equipment life. This all-metal flex-link coupling requires no lubrication or other maintenance.

Standard (Type 1, 2, or 2A) Deltaflex coupling are comprised of two hubs, an inner flange (with hardware), and an outer flange. Spacer (Type 3 & 4) Deltaflex coupling are comprised of two hubs, two spacer flanges (with hardware), and a drop out spacer.

Unlike Delta hubs, Round hubs are available in stainless steel (SS). Round hubs can also accommodate a larger max bore, but must always be mounted externally (no internal Type 1 mounting). Standard Round hubs come with two set screws at 120º.
