S-2224N18 1"-5 Two-Piece Clamping Acme Lead Screw Collars

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide finish on 12L14 carbon steel, extending service life in demanding industrial environments.
• Exceptional clamping force and stability from the two-piece construction, ensuring zero slippage on ACME lead screws during high-load operations.
• Precise and secure shaft mounting via the clamp-on design with two included socket head screws, enabling quick installation and reliable positioning.
• Optimized for ACME lead screw compatibility with 1"-5 right-hand Acme thread, delivering smooth engagement and reduced wear.
• Enhanced durability under mechanical stress thanks to Brinell 163 hardness, resisting deformation in repetitive motion applications.
• Ready-to-use assembly with pre-included clamping screws, reducing downtime and simplifying inventory management.
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

This two-piece clamping collar is engineered to solve critical challenges in ACME lead screw systems, where precise axial positioning and minimal backlash are paramount. The Black-Oxide 12L14 carbon steel construction provides a robust barrier against rust and abrasion, ideal for CNC machinery, linear actuators, and automated equipment exposed to oils and coolants. Its clamp-on design with socket head screws allows for effortless adjustment and firm retention, preventing misalignment in high-vibration environments. By integrating a 1"-5 ACME thread and right-hand direction, it ensures seamless compatibility with standard lead screws, reducing installation errors and enhancing operational reliability in industrial automation and motion control applications.

Specification Summary & Compliance

This collar adheres to Class 2A thread tolerances for ACME threads, with precise dimensions including 2-1/4" OD and 5/8" width. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, confirming its suitability for use in environmentally conscious industrial settings. The included clamping screws feature a 5/16"-24 thread size and are made from Black-Oxide steel, ensuring consistent performance and regulatory conformity.
