Precision Linear Motion Systems

Engineering Capability
Custom Motion Solutions Built for Precision and Performance
Thread-Craft designs and manufactures precision linear motion systems engineered for aerospace, defense, medical, and industrial applications where accuracy, durability, and reliability are critical. With decades of machining expertise and advanced manufacturing capabilities, we deliver custom solutions built to perform in the most demanding environments.
Core Capability
Custom Ball Screw Manufacturing
For more than 50 years, Thread-Craft has supplied custom ball screws, lead screws, and precision motion components to Fortune 500 companies across aerospace, defense, military, and industrial markets.
Our modern manufacturing facility is staffed by experienced craftsmen and engineers specializing in precision-ground and rolled-thread assemblies built to exact application requirements.
Unlike OEM manufacturers with limited production flexibility, Thread-Craft can manufacture virtually every return system used in the market today, including:
- Internal flopover return systems
- External return tubes
- Hybrid return designs
Our assemblies achieve mission-critical accuracies of up to 0.0002 in./ft, supporting high-performance applications requiring exceptional positioning precision.
Linear Motion Solutions

Ball Screws
Custom-engineered ball screw assemblies built from case-hardened alloys and configured with multiple return system options to match application demands.

Lead Screws
Precision acme and lead screw solutions engineered for controlled motion, durability, and consistent mechanical performance.

Roller Screws
High-load motion systems capable of handling extreme forces while maintaining superior accuracy and reliability.
Engineered for Reliability
Thread-Craft ball screw assemblies are designed with performance and longevity in mind:
- Case-hardened alloy construction for extended service life
- Full radius or Gothic arch thread forms
- Seamless external return tubes
- Mechanically secured internal assemblies for
enhanced safety - Nylon, brush, or felt wiper seals to protect against contamination
Every assembly undergoes rigorous inspection using advanced testing and measurement equipment to ensure consistent performance.
