Slotted Pins

Slotted pins Product Overview

Slotted pins are fasteners with axial or helical grooves that utilize elastic deformation to provide self-locking, anti-loosening, and damping functions. Widely used in power tools, door locks, windows, electric vehicles, construction machinery, and home appliances.

Slotted pins Key Advantages

1. Elastic Self-Locking & Anti-Loosening

Radial Expansion: Slotted design allows the pin to expand under pressure, creating a tight fit with the hole wall to prevent loosening.

High Vibration Resistance: Ideal for high-speed or high-vibration environments (e.g., engines, transmission systems).

No Additional Fasteners Needed: Eliminates the need for circlips, nuts, or other secondary components, simplifying assembly.

2. High Precision & Easy Removal
Tolerance Compensation: Adapts to varying hole sizes, reducing the need for high-precision machining.

Reusable Design: Elastic slotted structure allows multiple installations without damaging the hole wall (compared to solid pins).

Precision Alignment: Ensures high concentricity for components like gears and couplings.

3. Vibration Damping & Noise Reduction
Shock Absorption: Elastic slots absorb impact and reduce metal-to-metal noise (e.g., machine tool guides).

Reduced Wear: Minimizes rigid friction, extending the lifespan of both the pin and mating parts.

4. Cost Efficiency & Assembly Simplification
Lower Machining Costs: Accommodates wider hole tolerances, reducing machining precision requirements.

Quick Installation: Press-fit design requires no additional fastening steps.

Replaces Complex Fasteners: Can substitute threaded pins, rivets, and other multi-part fasteners, simplifying design and inventory.
