Parallel Pin

Parallel pins are a type of positioning pins, also called cylindrical pins. When used, they are inserted into the holes of the connecting objects to connect two parts. Xiaoguo Factory provides pins of various sizes. Contact us for more sizes. This type of positioning pin has low cost, simple structure, convenient use, high positioning accuracy, and strong load-bearing capacity. However, interference fit will make it difficult to disassemble and parts will be easily damaged. Do not disassemble too many times, otherwise the interference will be reduced and the positioning will be inaccurate.

Materials

The performance of parallel pin depends on the material they’re made from. For basic uses, they often use AISI 1045 carbon steel. In marine settings, where there’s a lot of moisture, AISI 316L stainless steel is the go-to choice. High-speed steel (HSS) pins are tough enough for rough, abrasive environments, while aluminum pins are picked when keeping weight low is important. Certifications like RoHS or REACH make sure they meet environmental rules. Testing the material,checking things like how strong it is (tensile strength) and how hard it is,helps ensure they work the same way every time, especially in applications where reliability matters a lot.

Maintenance

If you want the parallel pin to last a long time, you need to check and maintain it regularly. Mainly check its wear, rust or bending regularly. If you find any problems, you need to replace or maintain it in time. If the pin is used in places with high friction, you need to use grease that matches the material.For stainless steel ones, clean them now and then with gentle solvents to keep them from getting dirty. Store them in dry places where the temperature is controlled to avoid rust.

Customized

Q: Can parallel pin be customized in terms of dimensions and tolerances?

A: Yeah, this pin can be made to the exact diameters, lengths, and tolerance grades you need. For metric pins, there's a standard like ISO 2338. They use precision grinding to make sure the tolerances are really tight, like h8 or m6, so the pins fit well in assemblies. You can also get them with custom coatings or surface treatments, like zinc plating. Just give detailed drawings or specs so they match what your machinery or tools need.
