What is sworzeń walcowy?

A sworzeń walcowy (parallel pin) is a cylindrical mechanical fastener used to precisely align and securely join two or more parts together. It relies on a tight fit within pre-drilled holes to maintain its position and resist shear forces.

• Function: Provides precise alignment and strong, shear-resistant joints.

• Design: Solid cylindrical pin with tightly controlled diameter tolerances.

• Materials: Typically made of hardened steel, stainless steel, or brass. The choice of material depends on the application's requirements for strength, corrosion resistance, and temperature tolerance.

• Installation: Requires accurately drilled and reamed holes that are slightly smaller than the pin's diameter. The pin is then pressed or hammered into place.

• Applications: Widely used in machinery, automotive components, tooling, and various other applications where precise alignment and secure fastening are critical. Examples include hinge points, gear alignment, and fixture locating.

• Types: While fundamentally cylindrical, parallel pins can vary in length, diameter, and material. Some may have chamfered ends for easier insertion.

• Advantages: Simple design, high shear strength, precise alignment, and relatively low cost.

• Disadvantages: Requires precise hole preparation, can be difficult to remove, and may cause stress concentrations around the hole.
