Product Description

Industry Stainless Steel Double Pitch Hollow Pin Chains

Stainless steel double-pitch hollow pin chain
The hollow pin chain is made of the cold-forged CZPT bushing. This process ensures that the inner diameter of the bushing is always cylindrical. This unique hollow pin feature allows easy insertion of the crossbar without damaging the chain or rod. The hollow pin chain runs on a standard sprocket and a standard double-pitch sprocket. For the food handling conveyor, the hollow pin chain has ANSI standard short pitch series (40HP-80HP), double pitch series, standard roller (C2040HP-C2080HP), and large roller (C2042HP-C2082HP). Attachments or crossbars can be inserted at any desired spacing, which provides great design versatility. The chain can be changed without removing it from the conveyor.
Our hollow pin chain is as follows:
1. Hollow pin conveyor chain (MC series)
2. Hollow pin conveyor chain (FVC series)
3. Non-standard hollow pin conveyor chain
4. Hollow pin conveyor chain (ZC series)
5. Hollow pin chain
6. Stainless steel hollow pin chain

Can double chains be used in marine or underwater applications?

Yes, double chains can be used in marine or underwater applications, provided they are made from materials that offer good corrosion resistance and suitable lubrication is applied to prevent rust and ensure smooth operation. Marine and underwater environments pose unique challenges for power transmission systems due to the presence of saltwater, which can cause accelerated corrosion.

Here are some factors to consider when using double chains in marine or underwater applications:

1. Corrosion Resistance: The chains should be made from corrosion-resistant materials, such as stainless steel or special coatings, to withstand the harsh marine environment. This prevents rust and corrosion, ensuring the chains maintain their structural integrity and functionality over time.

2. Lubrication: Proper lubrication is crucial to protect the chain’s internal components from seawater exposure and corrosion. Lubricants with water-resistant properties should be used to ensure smooth operation and reduce wear.

3. Sealing and Protection: In some cases, additional seals or protective covers may be added to the chain to prevent water ingress and reduce the risk of corrosion. These protective measures help prolong the chain’s service life in marine environments.

4. Regular Maintenance: Regular inspection and maintenance are essential in marine and underwater applications. Routine checks for signs of corrosion, wear, or damage, along with proper cleaning and lubrication, help ensure the chains continue to function reliably.

5. Load and Environment: The specific application requirements, including the magnitude of the loads, the depth of submersion, and the presence of other environmental factors, should be carefully considered when selecting and using double chains in marine settings.

6. Certifications and Standards: Depending on the application and industry, adherence to specific certifications and standards may be necessary to ensure compliance and safety in marine or underwater environments.

By taking these factors into account and choosing appropriate chain materials and maintenance practices, double chains can be successfully utilized in marine or underwater applications, providing reliable power transmission despite the challenging environmental conditions.

How do double chains handle side loads and lateral forces?

Double chains are designed to handle side loads and lateral forces to a certain extent, but there are considerations to keep in mind to ensure optimal performance and longevity:

  • Chain Design: Double chains are constructed with multiple rows of plates, which provide increased surface area and contact points with the sprockets. This design enhances the chain’s ability to handle side loads and lateral forces compared to single-row chains.
  • Sprocket Alignment: Proper alignment of the sprockets is crucial to reduce lateral forces on the chains. Misalignment can cause uneven loading on the chain, leading to premature wear and potential failure. Regularly checking and adjusting sprocket alignment can help maintain the chains’ performance.
  • Guides and Tensioners: In applications with significant lateral forces, using chain guides and tensioners can help keep the chain properly aligned on the sprockets. Guides and tensioners minimize lateral movement, reducing wear and improving overall chain stability.
  • Load Distribution: Evenly distributing the load across multiple strands of the double chain can help prevent excessive stress on individual links. Proper load distribution is especially important in high-load and heavy-duty applications.
  • Maintenance: Regular maintenance, including lubrication and inspection, is essential to identify any signs of wear or misalignment. Addressing these issues promptly can extend the chain’s lifespan and maintain its ability to handle side loads effectively.

It’s important to note that while double chains offer better resistance to side loads and lateral forces compared to single chains, exceeding the chain’s design limits or neglecting maintenance can still lead to premature failure. Therefore, understanding the specific application requirements and using the appropriate chain size and type are crucial for optimal performance and reliability.

How do you select the right size and pitch for a double chain?

Choosing the right size and pitch for a double chain involves considering several factors to ensure proper fit and optimal performance in the intended application. Here are the key steps to selecting the right size and pitch:

  1. Identify the power transmission requirements: Determine the amount of power that needs to be transmitted by the chain, including the torque and speed requirements of the application. This information will help in selecting a chain that can handle the load and operate at the desired speed.
  2. Determine the chain type and standards: Double chains are available in various types and standards, such as ANSI (American National Standards Institute) and ISO (International Organization for Standardization). Identify the specific chain type and standard required for your application.
  3. Calculate the chain pitch: The chain pitch refers to the distance between the center of one roller to the center of the next roller in the chain. It is crucial to select the correct chain pitch to ensure smooth operation and proper engagement with the sprockets. The chain pitch is typically specified by the chain manufacturer and is measured in inches or millimeters.
  4. Consider the available space: Evaluate the available space in the application for accommodating the chain and sprockets. Ensure that there is sufficient clearance for the double chain to fit properly without interference or excessive tension.
  5. Consult chain manufacturer’s specifications: Refer to the manufacturer’s catalog or technical specifications to determine the appropriate chain size and pitch options available for the specific double chain series or type.
  6. Application-specific considerations: Take into account any specific requirements of the application, such as environmental conditions (temperature, humidity, presence of contaminants), load variations, operating conditions (continuous or intermittent operation), and the desired service life of the chain. These factors may influence the selection of a suitable chain size and pitch.

It is important to note that selecting the right size and pitch of a double chain requires careful consideration of the application’s requirements and consulting the manufacturer’s guidelines and recommendations. Improper sizing can lead to premature wear, decreased performance, or even failure of the chain system. Consulting with a knowledgeable engineer or chain supplier can help ensure an appropriate selection for the specific power transmission needs.
