GN 7062.2 semi-split shaft collars with additional mounting holes allow axles to be attached to a housing, or wheels and washers to be installed on shafts.
These shaft collars can easily be assembled with a high clamping force via the clamping screw without causing damage to the surface of the shaft or axle.
For sizes d1 = 30 to 36 mm, d3 is a tapped through hole; for sizes d1 = 42 mm and larger, d3 is a tapped blind hole.
