Our ball lock indexing plungers are advanced, high-safety positioning and locking components engineered to prevent accidental disengagement. Featuring an integrated ball-locking mechanism, the balls at the pin head automatically expand to create a positive, shake-proof lock once fully inserted. Pulling or pressing the release mechanism retracts the balls, enabling effortless adjustment.
They are highly sought-after in high-precision, high-vibration, and safety-critical industries:
Automotive & Aerospace Fixtures: Crucial for holding components tightly in position on automated assembly lines and welding jigs where machinery vibration occurs.
Heavy Machinery & Industrial Equipment: Provides a secure, zero-backlash limit and stop point for heavy sliding plates, rotating joints, and telescoping frames.
High-End Fitness & Medical Devices: Used in rehab beds, adjustable treatment tables, and heavy commercial gym systems to ensure user safety through redundant positive locking.
Aerospace & Defense Workholding: Serves as quick-release, high-shear-resistant temporary alignment pins for aerospace assembly structures.
Automatic Ball-Lock Mechanism: The built-in mechanical ball locking system ensures that once the plunger is engaged, it cannot be pulled out by vibration or axial force alone—providing maximum safety.
Ergonomic Stainless Steel Knob: Crafted with an ergonomic, polished metal knob that allows comfortable, smooth pulling force even under repetitive high-frequency operations.
CNC Precision Micro-Tolerances: The key locating pin and outer thread body are CNC ground to micro-tolerances, ensuring flawless concentricity and zero-play performance during locking.
High Shear & Radial Load Capacity: Constructed from hardened carbon steel or high-grade AISI 303/304/316 stainless steel to withstand severe mechanical wear and shear stresses.
Corrosion-Resistant Surface: Offers options of black oxide finish, nickel plating, or passivated stainless steel to ensure robust anti-rust protection in harsh outdoor or industrial environments.
We are a direct source manufacturer with over 10 years of extensive experience in precision CNC machining and high-precision metal component manufacturing.
Direct Factory Price Advantage: Eliminate intermediaries and trading agents. Source directly from our CNC workshop to achieve the best balance of cost and quality control.
Bespoke Custom OEM/ODM Services: We support complete custom manufacturing based on your CAD/3D drawings. Tailor the pin diameters, thread size pitches (M6 to M24), custom ball travel, pin lengths, and specialized materials (including titanium or brass).
State-of-the-Art Production Facility: Our factory is armed with advanced multi-axis CNC turning-milling machines and high-precision grinding centers, securing the absolute dimensional stability of every indexing plunger.
100% Quality Checked: Every batch undergoes rigorous inspection, including structural shear testing, mechanical push-pull cycle testing, and thread go/no-go gauge validation.
