S-6642K35 5/32"-21.3 x 1/2" Fast-Travel Ultra-Precision Lead Screws and Nuts

Key Features & Benefits at a Glance

• Enhanced wear resistance and consistent performance with the internal O-ring that automatically compensates for wear over time, extending service life in demanding applications.
• Rapid linear motion and increased positioning speed thanks to the 2:1 speed ratio and 0.094" travel per turn, ideal for fast-travel systems requiring quick, precise movements.
• Lightweight, corrosion-resistant operation provided by the durable Acetal Plastic construction, reducing system weight and maintenance needs without sacrificing strength.
• Simplified installation and secure mounting with the integrated flange design featuring two pre-sized mounting holes, ensuring stable attachment and alignment.
• Smooth, reliable motion transfer due to the rounded Acme thread and right-hand thread direction, minimizing friction and backlash for precise control.
• Compliance with global environmental standards, being RoHS 3 and REACH compliant, ensuring safe use in regulated industries and international markets.
• Optimized for precision applications with a dynamic thrust load capacity of 5 lbs, supporting controlled force in ultra-precision mechanisms.

Professional Applications & Engineering Value

This Acetal Plastic Flange Nut is engineered to address common challenges in fast-travel ultra-precision lead screw systems, where speed, accuracy, and durability are critical. The wear-compensating internal O-ring technology ensures long-term performance by maintaining thread engagement, reducing the need for frequent adjustments or replacements in high-cycle applications like automated positioning equipment and medical devices. Made from robust Acetal Plastic, it offers excellent dimensional stability and low friction, minimizing energy loss and wear on mating components. The 2:1 speed ratio and rounded Acme thread enable efficient motion conversion, making it ideal for CNC machinery, optical instruments, and other systems requiring rapid, precise linear actuation without compromising on dynamic thrust load capacity.
