Here’s all that you want to know about Hollow Pin

In Hollow Pin Chain, the pin has a hole, enabling the installation of several attachments. Usually these chains are used for conveyors.

The advantages of installing attachments into the hollow pin comprise the following:

• The hollow pin is at the center of articulation, and always keeps the pitch length. Irrespective of whether the chain is straight or wrapping around the sprocket, the center distance of attachments is the same always. Even when the chains bend, the mesh net does not expand or contract. With a cross rod over two chains, the load from the attachments is allocated to both sides of plates equally. The chain can completely use its strength and not wind.

It is easy to maintain, change, and adjust attachments.

Hollow Pins offer the functionality you need at 30-70% savings compared to machined contacts. Hollow pins are present in a vast range of configurations including: flats, Collars, seamed, barbs, or seamless, with open or closed ends.

Hollow Pin advantages comprise:

• High Precision

• Low cost

• Wide variety of materials and finishes

• Various shapes sizes and features

• Laser inspection and roll sorting

Hollow Pin chains are made with cold-forged solid bushings. This procedure guarantees the inside diameter of the bushing is wholly cylindrical all the way through. This distinctive hollow pin feature allows easy insertion of cross rods without damaging the chain or rods. Hollow Pin chain functions on standard sprockets and standard double pitch sprockets.

Hollow pin chains have chain pins with through-bore holes for mounting specifically designed attachments. They are frequently found as chain pairs in conveyance equipment or paternoster elevators. In these cases, matched pre-stretched chains are supplied.

Hollow pin chains offer great design versatility. Well-known companies manufacture hollow pin chains in American and European series, single and double pitch, with and without rollers, with and without bush. The double pitch series is supplied either rollerless or with carrier rollers. Cross Roads may be included into any link without disassembling the chain. The company can make double strands under request. Carbon steel nickelled plated, Delta Tone and stainless steel hollow pin chains are available. These chains are used in light handling, small conveyors usually using two parallel chains.

The final step in selecting the proper pin is to reevaluate the overall product design. Oftentimes, the pin evaluation process identifies new information about the assembly.
