Helical Milled Quenched & Tempered Rack
Helical milled racks of S45C steel in the quenched-and-tempered condition, with uniform through-hardness, roughly 30% higher strength than the standard version and markedly improved tooth-flank wear resistance. Suited to mid-range CNC equipment, textile machinery and paper-feed mechanisms of printing presses.
