APEX Precision Rack and Pinion

APEX high speed, low noise, and long life precision rack and pinion have extended travel capacities without adding inertia and high force capacities for high performance and long service life. High loading rates allow up to 204 kN. Like ball screw systems and linear motors, APEX precision rack and pinion are perfect for applications requiring a high force, travel capacities, and extreme precision. Precision rack and pinion use preload designs to engineer highly accurate systems for machine tools and measurement systems.

• Defined straightness, parallelism, and perpendicularity
• Helical angle and pressure angle with tolerance
• Geometrical tolerance of all dimensions

• Defined surface roughness of teeth
• Defined hardness and thickness of the hardened layer on teeth

APEX provides nine qualities of racks and eight variations of pinions with right- or left-handed helical teeth and ten qualities of racks and two qualities of pinions with straight teeth. Material options are carbon, alloy steel, or Q&T alloy steel.
