Standard Spindle Flanges

It is desirable to fit a flanged spindle if rotating shafts are constantly reversing. We also recommend flanged, rather than threaded, spindles for 125 (5″) and 150 (6″) Rotary Unions for ease of assembly and removal. Please add suffix “sf” to the rotary union part number.
