Spring Pull Pin with Clamping Knob
Clamping Indexing Plunger with Knob|Tool-Free Tightening × Reduced Vibration × Versatile Use
Spring pull pins with clamping knob combine precise positioning with added holding force, reducing vibration and unintended movement while enabling fast, tool-free adjustment in mechanical assemblies.
UJEN supplies spring pull pins with clamping knob for automation equipment, fixtures, and adjustable platforms, supporting improved holding stability and OEM/ODM customization through Taiwan-based manufacturing.
Core Function: Positioning with Integrated Clamping Force
The spring pull pin with clamping knob is designed for applications where accurate positioning alone is not sufficient. In addition to the spring-loaded indexing function, the clamping knob allows users to apply axial holding force after positioning, improving resistance to vibration and dynamic loads.
This integrated approach simplifies assembly design by combining positioning and fixation into a single fastening component.
Tool-Free Operation for Efficient Adjustment
Adjustment is performed entirely by hand. Users pull the knob to disengage the pin for repositioning, then release and rotate the knob to apply clamping force. This tool-free operation improves efficiency and reduces setup time, especially in applications requiring frequent adjustments.
Key Features
- Spring-loaded indexing pin with automatic re-engagement
- Manual clamping via top knob without tools
- Improved resistance to vibration and unintended movement
- User-friendly operation for frequent adjustment tasks
- Available in multiple sizes and configurations
- ROHS compliant for global environmental requirements
Typical Applications
- Industrial rails and linear platform alignment systems
- Jigs, fixtures, and mold setups requiring quick clamping
- Assembly modules with adjustable locking positions
- Fitness and medical equipment demanding stable adjustment
- Structures exposed to vibration or repeated repositioning
OEM / ODM Customization Support
UJEN offers OEM and ODM support for clamping indexing plungers, including customization of pin diameter, stroke length, clamping force, thread size, and knob design. Our engineering team works closely with customers to ensure reliable integration and long-term performance in real-world applications.
When pull pin specifications vary in thread size, plunger diameter, external dimensions, materials, and surface finishing, manual browsing may take time. For faster selection, use Advanced Search below or the shortcut at the top right to filter by dimensions, materials, and functional requirements.
