The insert is formed of a third material different from the first material and the second material.

Polymeric thread insert for high load leadscrew and nut

A bracket assembly includes a first bracket arranged along a damping axis and having a clevis body, a second bracket, and a vibration isolator including an elastomeric body. The second bracket is arranged along the damping axis and has a clevis portion and a mount portion. The clevis portion slidably receives the clevis body of the first bracket. The elastomeric body is arranged axially between the first bracket and the second bracket and is fixedly arranged between the clevis portion of the second bracket and the clevis body of the first bracket through an on-axis load path and through an off-axis load path extending through the bracket assembly. Actuator arrangements and methods of damping vibrational forces are also described.
