Our shaft clamp kit allows a shaft, from 7mm to about 16mm, to be clamped anywhere along an Open Beam structure. One common usage case would be for clamping a linear bearing rod for a RapRep type machine.
Sold in a pack of 4, which allows for clamping both ends of a shaft (unsupported cantilever applications are not recommended). The kit also comes with 4 pieces of M3x25mm hex head cap screw and 4 pieces of M3 x 35mm hex head cap screw to form the threaded stud that anchors into the OpenBeam 1515 extrusion.
Engineering drawings and application notes can be found here.
