June 20, 2011 -Wittenstein introduces Performance Class Rack, a case hardened rack series which partners the rack with gearbox / actuator and pinion for greater system efficiency and optimal performance. The Performance Class rack is available in two options - Performance (standard hole pattern) and High Performance (optimized hole pattern for high feeding forces). The Performance Class racks undergo case hardening which results in rack for the most demanding applications. The hardening process provides strength at the tooth root of the rack, enabling the rack to be resistant to high stresses and allowing higher feeding forces to be transmitted. The case hardened rack is a main component of the new High Performance Linear System.
This system doubles performance with less space, and shows high efficiencies along with high power density and high positioning accuracy.
