No shaft marring.... EVER !

A compact, light-weight design    easy mounting/dismounting
Torksleeve A  has emerged as one of the most elegant and simple solutions for mounting
mechanical components onto a shaft for substantial toque transmission applications.
Slotted cylindrical inner and outer sleeves are threaded into each other making a single unit.
When installed onto a shaft with a component mounted on them, the two sleeves are
tightened into each other.  The shallow angle of the asymmetric thread amplifies radial
forces causing the outer sleeve to expand, gripping the component, and the inner sleeve to
contract, gripping the shaft.
