S-2207N12 3/8"-16 Two-Piece Clamping Acme Lead Screw Collars

Key Features & Benefits at a Glance

• Superior corrosion resistance and reduced light reflection with the durable Black-Oxide finish on 1215 Carbon Steel, extending service life in harsh industrial environments.
• Exceptional clamping force and secure shaft retention thanks to the two-piece clamp-on design, preventing slippage on Acme lead screws during high-load operations.
• High material strength and wear resistance from Brinell 167 hardness, ensuring reliable performance and minimal deformation under repeated use.
• Easy installation and precise adjustment with the included 6-32 socket head clamping screws, allowing for quick assembly and disassembly without specialized tools.
• Accurate thread engagement and smooth motion transfer with the 3/8"-16 Acme right-hand thread, compatible with standard Acme lead screws for consistent operation.
• Broad industrial compliance and environmental safety by meeting RoHS 3 and REACH standards, making it suitable for global supply chains and regulated applications.
• Optimized for heavy-duty applications with a robust 7/8" OD and 11/32" width, providing a stable fit for demanding machinery and automation systems.

Professional Applications & Engineering Value

This two-piece clamping collar is engineered to address common challenges in industrial settings, such as vibration-induced loosening and shaft misalignment on Acme lead screws. Constructed from Black-Oxide 1215 Carbon Steel, it offers enhanced durability and resistance to rust, which is critical in environments exposed to moisture or chemicals. The clamp-on shaft mount type ensures a tight, reliable grip without damaging the screw threads, while the Acme thread type and right-hand thread direction provide efficient power transmission in automation, CNC machinery, and linear motion systems. By incorporating socket head screws for secure fastening, it simplifies maintenance and reduces downtime, making it an ideal industrial collar for high-precision applications where consistent performance is paramount.
