Double Pitch Transmission Chains 208/210/212/216/220/224/228/232

Double pitch transmission chains, also called extended pitch conveyor roller chains, are used in low-speed conveyor applications. They feature larger diameter rollers and hollow pin designs for extra strength. These chains can be made of steel, nickel plating, zinc plating, or engineering plastics. Some have a special oversized diameter and can handle greater loads than standard chains. Regardless of their material, they can provide years of reliable service in industrial settings.

Double pitch transmission chains come in a variety of sizes and pitches. These chains are similar to ASME B29.3 standard products, but with an extra pitch for higher strength. These chains are best suited for industrial and agricultural applications. Ever-power offers a variety of double pitch roller chain attachments, including sprockets, pre-stretched chains, and double strand roller chains. Once you’ve chosen the right double pitch transmission chain for your application, you’ll be able to save money on maintenance costs over the long run.

Double pitch roller chains are available in different configurations and styles, with different roller diameters. Standard chains are made of stainless steel with straight sidebars, while oversized double pitch chains are made with roller diameters larger than the side plates. Oversized double pitch chains are used in applications where a product is placed on top of the chain, or where guide tracks are used to guide the product. There are also different styles, including hollow pin double pitch roller chains.

Double Pitch Transmission Chains Features

Double pitch transmission chains feature a higher roller pitch than the standard chain. This provides superior efficiency and is an excellent choice for power transmission applications. These chains are available with a variety of configurations and styles. Standard double pitch transmission chains are supplied with sidebars and rollers of the same diameter, while oversized roller double pitch transmission chains have roller diameters larger than the side plates. These chains are commonly used in applications where the product is positioned on top of the chain or on a guide track.

ANSI and European standards are the basis for double-pitch roller chains. These chains have a double-pitch design, but are otherwise the same as standard chains. They are an economical solution for low speeds and low loads. These chains are available in stainless steel and nickel plating versions. They are designed to be lightweight while providing durability. ANSI standard sprockets have at least 30 teeth. However, it’s important to note that larger-pitch roller chains have thicker plates and longer attachments.

In addition to their double-pitch design, double-pitch chains are also manufactured to meet ISO 606 specifications. These transmission chains are commonly used in light load applications, such as agricultural machinery and forestry equipment. Double-pitch transmission chains are manufactured to meet the same specifications as single-pitch chains, but are a more affordable option for applications requiring large centre distances. They are also lighter than single-pitch chains and are constructed with the same high-quality standards.

Sprockets For Double Pitch Transmission Chains

If you’re building a vehicle, you’ll need sprockets for double pitch transfer chains. A double pitch chain has a higher tooth surface, and you can’t use a single pitch sprocket. Not only will this cause excessive shock and vibration, it could cause premature wear to the chain. Luckily, sprockets for double pitch transmission chains are readily available.

Double pitch sprockets are available in single tooth and double tooth designs. Single tooth sprockets have similar behavior to standard roller chain sprockets, but the toothing of the double pitch sprockets can increase durability. Double-toothed sprockets are available in full tooth steps, half-tooth steps, and single tooth steps. The teeth are double-toothed, so that only part of the chain is used at a time. The remaining teeth can be reused during chain exchange.

The sprockets for double pitch chain assemblies are typically made of metal or reinforced plastic. They are similar to bicycle chains because they share a similar wheel-shaped design with teeth. However, they are designed to interact with different kinds of chains. Most sprocket and chain assemblies function in a similar fashion. Before purchasing, it’s helpful to understand your system’s specifications.

The types of sprockets used for double pitch chain applications vary by country. Japanese sprockets are subject to JIS standards, while Korean sprockets fall under the KS B 1407 standard. German sprockets, on the other hand, fall under the DIN code 8188. The German standard, DIN code 8187, also exists, but it’s becoming increasingly rare.
