Miniature SC 75M-HC shock absorbers from Ace Controls Inc., Farmington Hills, Mich. (acecontrols.com), feature short rod-ready times or the time needed between hits for the rod to reset. The shock also has short times through strokes and rapid-repeat strokes. All of these generate faster cycling and gains in production. The relatively small size 3 in. long and 0.55 in. in diameter with a 0.2-in. stroke means the lightweight (0.1-lb) shocks fit in most highspeed production equipment. The units are housed in a steel body with a black-oxide finish and use a hardened-steel piston rod. They operate in temperatures from 32 to 150°F and have a built-in mechanical stop. There are three models. The M5's effective weight is 2.2 to 18 lb and impact velocity ranges from 1.5 to 13.5 fps. The M6 effective weight ranges from 15 to 172 lb and its impact velocity goes from 0.5 to 5.2 fps. And the M7 has effective weights of 165 to 1,760 and impact velocities from 0.15 to 1.6 fps.
