S-3405N082 5/8"-5 x 1 45/64" Ball Screws and Nuts

Key Features & Benefits at a Glance

• Enhanced Durability – Rockwell C56 hardness provides exceptional wear resistance and long service life in demanding industrial applications.
• Superior Load Handling – Dynamic thrust load capacity of 770 lbs ensures reliable performance under heavy mechanical stress.
• Minimal Backlash – Maximum backlash of only 0.015" delivers precise positioning and repeatable accuracy for high-precision machinery.
• Wide Temperature Tolerance – Operates reliably from -40° to 300° F, making it suitable for both extreme cold and high-heat environments.
• Corrosion-Resistant Finish – Black-oxide coating on alloy steel protects against rust and extends component lifespan in harsh conditions.
• Efficient Motion Transfer – 0.2" travel per turn with a single thread start enables smooth, controlled linear motion with minimal effort.
• Left-Hand Thread Compatibility – UN-standard 15/16"-16 left-hand external threads offer design flexibility for specialized assembly and reverse-motion systems.

Professional Applications & Engineering Value

Engineered for precision motion control, this ball screw nut combines black-oxide alloy steel construction with a left-hand UN thread to address critical industrial needs. Its Rockwell C56 hardness and 770 lbs dynamic thrust capacity make it ideal for CNC machinery, automated positioning systems, and heavy-duty actuators where load endurance and minimal deflection are paramount. The 0.2" travel per turn and low 0.015" backlash ensure accurate, repeatable movements in applications like linear guides, robotics, and packaging equipment. With a broad temperature range of -40° to 300° F, it performs reliably in environments from freezing warehouses to high-temperature manufacturing zones, reducing downtime and maintenance costs.
