308 Pintle Chain

The 308 pintle chain is distinguished by its heat-treated, high-quality components, high tensile strength and extreme durability. The 308 pintle chain is ideally suited for material spreading equipment, hay handling equipment, wood processing and more. The chain also features quad-staked pins that are fully heat-treated to provide maximum durability and strength. In addition, the chain is oil hardened during the heat treatment process to ensure ideal and proper medal hardening. This 308 pintle chain also features a carefully designed open barrel design that minimizes pin-to-surface contact and prevents the material buildup that often causes chains to freeze. Most importantly, the open barrel design also helps remove buildup from the sprockets, thereby extending the overall life and performance of the chain and sprockets.

308 Pintle Chain

A pintle chain is a type of conveyor chain that consists of interconnected metal plates with cylindrical pins or "pintles" that hold the plates together. The 308 pintle chain is a specific type of pintle chain that has a pitch (distance between the centers of adjacent pins) of 3.08 inches. This type of conveyor chain is commonly used in heavy-duty applications such as agriculture, forestry, and mining equipment. It is designed to handle high loads and withstand harsh environments. The 308 pintle chain is available in a variety of configurations to meet specific application requirements.

308 Steel Pintle Chain Features

308 steel pintle chains are a type of conveyor chain that consists of interconnected steel links or pintles. Here are some of the features of 308 steel pintle chains:

  • Material: The chain is made of high-quality carbon steel which provides excellent strength, durability, and corrosion resistance.
  • Pintle shape: The pintles are oval-shaped and have a flat top and bottom, which allows them to slide smoothly over the conveyor bed.
  • Chain pitch: The chain pitch, or the distance between the centers of two consecutive pins, is 3.08 inches, which makes it suitable for conveying heavy loads.
  • Attachment options: The chain can be equipped with various types of attachments, such as extended pins, straight or bent attachment plates, and slats, depending on the specific application requirements.
  • Lubrication: The chain requires periodic lubrication to prevent wear and extend its service life. It can be lubricated with oil or grease, depending on the operating conditions.
  • Applications: 308 steel pintle chains are widely used in heavy-duty conveying applications, such as lumber mills, paper mills, automotive plants, and metalworking facilities. They can also be used in agricultural equipment, such as grain elevators and feed conveyors.

308 steel pintle chains are a reliable and robust conveyor chain option for applications that require heavy-duty conveying and long service life.

Sprockets for Steel Pintle Chains

Sprockets for steel pintle chains are typically made from materials that are durable and wear-resistant, such as steel or cast iron. The sprocket teeth are designed to mesh with the links of the pintle chain, providing a positive drive and minimizing slippage.

The pitch of the sprocket teeth must match the pitch of the pintle chain to ensure proper engagement. The number of teeth on the sprocket will depend on the desired speed ratio and torque transmission requirements.

When selecting a sprocket for a steel pintle chain, it is important to consider factors such as the operating environment, load requirements, and desired speed ratio. Proper lubrication and maintenance of both the chain and sprocket can also help to extend their service life.
