Vibration-Resistant Slotted Spring Pins

Interlocking teeth help these pins resist sliding when exposed to vibration. Also known as roll, tension, split, and expansion pins, they have a slot that presses closed when the pins are inserted so they don't flex after installation. Use them for fastening, pivoting, and holding.

Squeeze the pins closed and install them in a hole. Tension holds them tight against the whole wall. The ends are chamfered to aid insertion.

Breaking strength is measured as double shear, Which is the force required to break a pin into three pieces. Pins are made of vanadium steel for excellent wear resistance.

Spring pins are a kind of headless hollow column with axial groove; both ends are chamfered and are used for positioning between parts, connecting, fixing, etc.; they need to have good elasticity and resistance to shear, and the outer diameter of such pins than assembly hole diameter is slightly larger.

An elastic pin, also known as a spring pin, is adjustable, with good elasticity and anti-shear force of the pin parts. It is mainly used for positioning, connecting, and fixing between parts.

Classification

1. Light elastic cylindrical pins

2. Heavy Duty Cylindrical Pins

The main difference between light and heavy is the thickness of the material and the width of the chamfer; the thickness of the heavy spring pin material and the width of the chamfer are more significant than the light.

Elastic Dowel Pins with teeth

1. Light elastic cylindrical pin

2. Heavy-duty elastic cylindrical pin

The ordinary elastic cylindrical pin shape is similar, and the difference is that its axial groove is the shape of the staggered wave teeth.

Rolled Elastic Dowel Pins

1. Light-duty rolled elastic cylindrical pins

2. Heavy-duty rolled elastic cylindrical pin

Installation points of the elastic pin.

1. The elastic pin is assembled with a hammer.

2. the pin holes should be staggered when assembling the outer and inner pins.

3. When the elastic pin is assembled, the direction of the pin opening should be the same as the direction of force on the workpiece.

4. After the elastic pin is assembled into the workpiece, the pin should be made in place, basically flush with the surface of the workpiece.
