S-2207N17 1 1/4"-5 Two-Piece Clamping Acme Lead Screw Collars

Key Features & Benefits at a Glance

• Superior Durability: Crafted from Black-Oxide 1215 Carbon Steel with a Brinell 167 hardness rating, this collar resists wear and deformation under high-load conditions, extending service life.
• Reliable, Non-Slip Clamping: The two-piece clamp-on design with two included socket head screws ensures a secure, concentric grip on your Acme lead screw, preventing axial movement.
li>Precision ACME Thread Compatibility: Features a 1 1/4"-5 ACME right-hand thread for a perfect, backlash-minimized fit with standard Acme lead screws, ensuring smooth and accurate linear motion.
• Corrosion-Resistant Finish: The black-oxide surface treatment provides a protective layer that guards against rust and reduces friction in demanding industrial environments.
• Effortless Installation & Adjustment: The split construction allows for easy mounting and removal without disassembling the entire drive system, saving valuable maintenance time.
• Robust Construction for Heavy-Duty Use: With a substantial 2 1/16" OD and 1/2" width, the collar offers a large bearing surface for enhanced stability and load distribution.
• Global Regulatory Compliance: Meets RoHS 3 and REACH standards, ensuring the product is safe for use in regulated markets and environmentally conscious operations.

Professional Applications & Engineering Value

This two-piece clamping Acme lead screw collar is engineered to solve critical challenges in power transmission and linear motion systems. The Black-Oxide 1215 Carbon Steel construction provides the necessary Brinell 167 hardness to withstand high thrust loads and repetitive stress without failing, a common pain point in CNC machinery, automated actuators, and heavy-duty positioning equipment. Its Acme thread form ensures superior force transmission and minimal backlash compared to standard V-threads, which is vital for maintaining precision in applications like 3D printers, lathes, and lifting mechanisms. The clamp-on shaft mount type allows engineers to securely position the collar anywhere along the screw without needing keyways or set screws that can damage the shaft, preserving the integrity of expensive Acme lead screws and reducing long-term maintenance costs. This design is ideal for industries requiring reliable, repeatable performance without compromising on ease of assembly.

Specification Summary & Compliance

This collar is manufactured to precise inch system dimensions, including a 1 1/4"-5 ACME thread with a right-hand thread direction for standard compatibility. It includes two 1/4"-28 socket head clamping screws made from Black-Oxide Steel to ensure uniform clamping force. The product is confirmed to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, adhering to stringent environmental and safety regulations for industrial components.
