Here is a selection of Motion Constrained flange mount shaft collars/shaft couplers for bores ranging from 1/4" to 3/4" bore. These are custom machined for our internal applications but are equivalent to McMaster products (see table above) with the exception of having all tapped threads and at a much lower price.
