High Performance and Durable Hollow Pin Chains
A special link pin design distinguishes hollow pin roller chains from standard roller chains. Hollow pin chain links have a similar construction to ISO standard roller chains; they consist of pin, bushing and small pulley, so most chains of this type are compatible with the same sprockets as corresponding standard chains. We can supply these chains double-paired, as double-stranded processing is conventional for most applications.
Hollow pin chains operate without bushings in light use, usually on small conveyors using two parallel chains.
Hollow pin chains are used for a wide variety of industrial applications. It is used by connecting a carrier piece between two parallel chains or by passing a steel bar. Since two chains usually run in parallel (double helix), we manufacture in pairs of matching chains. Hollow pin chains have chain pins with through holes for mounting specially designed attachments. The general working principle of chains with hollow pins is based on connecting a rod, shaft or a different carrier piece that is passed through hollow pins. Hollow pin chains are often used as carriers in chip conveyors, bucket elevators and roller belt systems.

What Are Hollow Pin Chains Used For?
- Designed with pins extending from the pitch axis for short-pitch or long-pitch chains, these chains are manufactured from the best materials with excellent machining techniques according to customer requirements for the bearing of special attachments, pushing or pulling operations. Hollow pin chains are produced in desired lengths and dimensions and can be easily mounted and dismounted thanks to their protrusions. They are easier to transport and install than other chains. Hollow pin chains are specially produced and made of stainless steel and offer economical options with stylish designs.
- Pins are mounted on the chain at desired intervals according to conveyor requirements. This ensures that the chain operates efficiently and for a long time at high levels. These chains are produced in carbon steel, zinc-chrome plated and stainless steel.
- One of the main advantages of hollow pin chains, also called chains with extended pins, is that they can handle larger loads and transmit power over longer distances. The protruding pin of these chains leaves more space between the rollers, allowing the chain to absorb more shock and vibration, reducing wear and increasing its overall lifespan. The larger rollers also provide more surface area for the chain to rest on, helping to distribute the load more evenly and reduce the risk of breakage.
- Hollow pin chains are used to transport functional components. There are two different versions of the chain: single-sided and double-sided extended double-way and triple pins with groove inserts for locking springs, Seeger rings or E-rings, and holes for splints or wire nails are provided as security elements. Depending on the application, they can be provided with different pin diameters and special forms (grooves, etc.) that allow the handling of various functional components.
- The high precision of roller chains made with protruding pins also means they can operate in extreme environments, including high temperatures and low temperatures. These conditions can cause other types of chains to become brittle or weak, but roller chains made with lug pins can withstand these environments without problems.

A 40 pitch hollow pin chain is a type of chain typically used in industrial applications. It is made up of a series of hollow pins that are connected together by links. The hollow pins allow the chain to flex and bend, making it ideal for use in conveyor systems and other applications where a flexible chain is required.
A hollow pin chain is a type of chain that is held together by hollow pins. Unlike solid pins, which are held in place by a set screw, hollow pins are held in place by a circlip. To remove a hollow pin, you will need to use a chain tool to push the pin out from the inside of the link.
A hollow pin chain is a chain that uses hollow pins. The advantage of using hollow pins is that they are lighter than solid pins, and thus can make the chain lighter overall. Additionally, hollow pins can sometimes be more accessible to remove and replace than solid pins.
Hollow pin chains are used in many different applications, including conveyors, packaging machinery, and material handling systems. They are also used in agricultural and forestry equipment, as well as in some types of construction equipment.
Hollow pin chains work by utilizing the unique structure of hollow pins that allow for easy attachment and configuration. The hollow pins are open in the center, enabling various components, such as cross rods or attachments, to be inserted into the chain without disassembling it. This adaptability makes hollow pin chains especially useful in conveyor systems or applications that require frequent changes in setup.
The chains typically operate by moving around a sprocket or pulley system. As the sprocket rotates, it engages the chain’s pins and links, which then move the chain forward. The hollow pins reduce the overall weight of the chain while maintaining strength, allowing the chain to efficiently transfer loads across mechanical systems.
Determining the correct size of a hollow pin chain involves measuring several key dimensions:
1. Pitch: This is the distance between the center of one pin to the center of the next pin. It is one of the most critical measurements as it determines the overall length of the chain links.
2. Pin Diameter: The diameter of the hollow pins should be measured to ensure that they match any attachments or components that will be used with the chain. The internal diameter of the hollow pin is essential for determining what kind of rods or accessories can fit inside.
3. Link Width: The width of the links between the pins can vary depending on the strength and load-bearing requirements of the chain. For lighter applications, narrower links might be sufficient, while heavy-duty operations will require wider links.
4. Chain Length: This can be determined by the total number of links or sections in the chain. In some cases, custom lengths are made for specific applications.
Once these measurements are taken, you can refer to manufacturer specifications or catalogs to match your measurements with the appropriate chain size.
When choosing a hollow pin chain, selecting the right material is crucial for ensuring durability, performance, and safety in your application. The main materials to consider are:
- Carbon Steel: This is a common material used for hollow pin chains in general-purpose applications. It offers a good balance of strength, wear resistance, and affordability.
- Stainless Steel: For applications in corrosive environments or where hygiene is essential, stainless steel is an excellent choice. It resists rust and corrosion, making it ideal for food processing, pharmaceutical, or chemical industries.
- Nickel-Plated Steel: If you need additional protection against corrosion but want to retain the strength of steel, nickel-plated chains are a good option. The nickel coating helps to resist rust in environments with exposure to moisture or chemicals.
- Plastic or Polymer: In lighter applications where weight is a concern, or in environments where metal contamination must be avoided (like in food production), plastic hollow pin chains can be a viable alternative. However, they are not as strong as metal chains and are generally used for less demanding tasks.
- Heat-Treated Steel: For heavy-duty applications that require extra strength and durability, heat-treated steel hollow pin chains can withstand higher stress levels and extended operational periods without compromising performance.
Choosing the right material depends on the working environment, load requirements, and potential exposure to corrosive substances.
Proper maintenance and timely repair are crucial to extending the life and ensuring the efficiency of hollow pin chains. Here’s how to approach maintenance and repair:
- Regular Inspection: Frequently inspect the chain for signs of wear, such as elongation, broken pins, or rust. If any part of the chain shows excessive wear, it should be replaced immediately to prevent system failure.
- Cleaning: Chains should be regularly cleaned to remove dirt, grease, and debris that can build up in the hollow pins. For chains used in food processing or corrosive environments, cleaning with approved solutions is vital to maintain hygiene and prevent rust formation.
- Lubrication: Proper lubrication reduces friction between the pins and links, preventing wear and tear. Use lubricants that are compatible with the chain material. For example, stainless steel chains may require food-grade lubricants, while standard chains can use more general-purpose oils.
- Tension Adjustment: Regularly check the tension of the chain to ensure it’s neither too loose nor too tight. Loose chains can lead to slippage and excessive wear, while overly tight chains can cause premature stretching or breakage.
- Replacing Damaged Parts: If individual components such as pins or links are damaged, they can often be replaced without the need to change the entire chain. This can save on maintenance costs while keeping the system running efficiently.
By performing these maintenance tasks regularly and addressing any issues promptly, the lifespan of hollow pin chains can be extended, reducing downtime and improving overall performance.
