Apex Dynamics Helical Pinions - Curvic Plate (Series A, Module 2-10)

APEX Dynamics helical-teeth pinions with curvic plate / en iso 9409-1-a interface for high-precision rack-and-pinion drives, module 2 to 10.

Key features

Helical teeth matched to APEX helical racks; left-hand helix pairs with right-hand helical racks
Interface: Curvic plate / EN ISO 9409-1-A
Carburized alloy steel, case hardened to about 60 HRC, teeth ground to reduce noise and wear
Max. permitted torque and feed force per rack quality given in the catalog torque tables
Backlash depends on center height; contact APEX for adjustment guidance
Curvic coupling gives all-teeth contact between pinion and gearbox flange; order as set or pinion only
