MKR
locknuts for NRS 15x2 to 75x30
Conventional locknuts may not be suitable in a typical roller screw
application due to the high axial load generated. Nook series MKR
locknuts are designed to carry high axial forces while minimizing
the rotational inertia, an important benefi t in high dynamic applications.
MKR locknuts are designed to carry high axial load, have high loosen-ing
torque and are manufactured with high accuracy to optimize the load
on the thread interface.
