Professional Applications & Engineering Value

This precision Acme lead screw nut is engineered to solve critical challenges in motion control systems. The PET plastic material provides inherent lubrication properties, reducing the need for external lubricants and preventing contamination in clean environments like packaging, medical devices, and laboratory automation. Its left-hand Acme thread is essential for creating opposing motions in dual-lead screw assemblies or for applications where reverse-thread logic is required. The combination of a Class 2C thread fit and a 0.1" travel per turn delivers exceptional positional accuracy, making it ideal for fine-adjustment mechanisms, linear actuators, and precision staging equipment where 350 lbs of dynamic thrust capacity is necessary to handle significant loads without failure.

Specification Summary & Compliance

This component features a 3/8"-10 left-hand Acme thread with a Class 2C thread fit per standard inch-based thread classifications, ensuring dimensional accuracy and compatibility. It is manufactured from PET Plastic and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety standards for industrial use.
