• Precision ACME Thread Compatibility: 7/8"-6 right-hand ACME threads ensure accurate engagement and smooth motion transfer with standard lead screws.
• Robust One-Piece Construction: Solid design eliminates potential weak points, providing consistent strength and dimensional stability under load.
• Regulatory Compliance Assurance: Meets RoHS 3 and REACH environmental standards, ensuring safe use in regulated markets and applications.
• Optimized for Industrial Use: 2 1/8" OD and 5/8" width offer a substantial clamping surface for high-torque applications and easy installation.

Professional Applications & Engineering Value

Engineered for precision motion control systems, this clamping ACME lead screw collar solves critical alignment and slippage challenges in industrial machinery. The black oxide 12L14 carbon steel construction combats corrosion while maintaining the Brinell 163 hardness needed to withstand repetitive axial loads. Its one-piece design and right-hand ACME threads (7/8"-6) provide reliable, backlash-resistant coupling to ACME lead screws, essential for CNC equipment, linear actuators, and automated positioning systems. The included socket head clamping screw ensures a vise-like hold, preventing unintended movement and maintaining precision in high-vibration environments. This collar delivers consistent performance where durability and thread integrity are non-negotiable.
