Abstract
A motion control apparatus () in the form of a linear brake includes a camshaft () rotatable in a housing () moveable along a linear rail (). The camshaft () is rotated by a gear motor () causing an eccentric engagement portion of a cam follower () to abut with a facing () which engages the linear rail () to provide a clamping force thereon. A damper () is received on a dowel pin () secured to the housing () and received in a U-shaped groove in the camshaft () to inhibit further rotation of the camshaft (). A shim () separates the outer races of the bearings () receiving the camshaft () to preload the first and second bearings ().
