Spring Pins (Roll Pins / Slotted Spring Pins)
Spring Pins, also known as roll pins or slotted spring pins, are versatile, self-retaining mechanical fasteners designed to secure components in place while accommodating dynamic loads, vibrations, and thermal expansion. Their unique slotted cylindrical shape and elastic properties make them ideal for applications requiring flexibility, durability, and ease of installation.
Key Features
Elastic Design:
Manufactured from high-quality spring steel or stainless steel, these pins flex slightly during insertion, creating a secure, friction-fit hold. The split design allows the pin to compress and expand, ensuring consistent tension even in high-stress environments.
Vibration Resistance:
The spring-like action of the pin absorbs shocks and vibrations, preventing loosening over time. This makes them ideal for machinery, automotive, and aerospace applications.
Easy Installation:
No specialized tools are required. Simply align the components, insert the pin into a pre-drilled hole, and let the pin’s elasticity secure the assembly.
Durability:
Heat-treated for enhanced strength and corrosion resistance, spring pins withstand harsh conditions, including extreme temperatures and exposure to chemicals.
Versatility:
Available in multiple sizes (diameters ranging from 0.8mm to 20mm) and materials (carbon steel, stainless steel, or coated variants), they suit diverse industrial needs.
Applications
Spring pins are widely used in:
- Automotive: Securing gears, shafts, and linkages.
- Aerospace: Assembling lightweight, high-strength components.
- Industrial Machinery: Aligning bearings, pulleys, and hydraulic systems.
- Consumer Electronics: Fastening small mechanisms in devices.
- Construction: Joining structural parts with tolerance for movement.
How It Works
The pin’s slotted body compresses slightly when inserted into a hole slightly smaller than its nominal diameter. Once in place, the pin exerts radial pressure against the hole walls, creating a firm, rattle-proof connection. Unlike solid pins, spring pins distribute stress evenly, reducing wear and extending service life.
