Locking Assemblies MAV 1008 provide a rigid, zero-backlash, fric#onal keyless connec#on between a sha' and hubs
such as gears, pulleys, cams, levers, rotors and many others.
They are suited for transmi*ng torque, axial load, bending moment and radial load, separately or in combina#on.
Applied loads are transmi-ed via pressure and fric#on across the fi*ng surfaces between Locking Assembly, sha'
and hub bore.
In #ghtened condi#on, Locking Assemblies exert high radial pressure on sha' and in hub bore.
•
Locking Assemblies MAV 1008 are supplied ready for installa#on and are composed of (fig. 1):
◦
one front thrust ring (w/ complete slit up to size 180x235, w/ staggered slit from size 190x250)
◦
one rear thrust ring (w/ complete slit up to size 180x235, w/ staggered slit from size 190x250)
◦
