Product description

Split shaft collars GN 7072.2 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. As compared to semi-split shaft collars, split shaft collars can also be assembled radially.

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.
