Abstract
Friction disks, such as rotors and stators, including keyed wear liners are disclosed. The friction disks may include a core and a replaceable wear liner coupled to each side of the core. The wear liners may include a plurality of keys which engage key notches in the core. The key notches may prevent the wear liners from rotating with respect to the core in response to a shear force, such as a force applied during braking.

A stator comprising:
- a core comprising:
- a spine;
- an inner core having a thickness greater than the spine;
- a lug in the inner core;
- and
- a key notch recessed into a radially outer portion of the inner core, wherein the core is a single integral component comprising the spine, the inner core, and the lug;
- and
- a first wear liner coupled to the spine, the first wear liner comprising an annular ring and a stator key, wherein the stator key mates with the key notch in the inner core.
