5. ANSI-compliant: The 81X chain is manufactured to ANSI specifications, which ensures that it meets the highest standards of quality and performance.
Overall, the 81X conveyor chain is a high-quality, durable, and versatile chain that is a good choice for a variety of demanding applications.
▍Applications of 81X Lumber Conveyor Chain:
81X lumber conveyor chain is a type of chain commonly used in the lumber industry for conveying large and heavy loads of lumber. The chain is designed with large, sturdy links that can withstand high loads and resist wear and tear. Some of the common applications of 81X lumber conveyor chain include:
- Lumber conveyors: This is the most common application for the 81X chain. Lumber conveyors are used to move logs and lumber around sawmills and lumberyards.
- Trimmer saws: 81X chain is often used on trimmer saws, which are used to cut logs into smaller pieces.
- Stackers: 81X chain is also used on stackers, which are used to stack lumber.
- Transfer conveyors: Transfer conveyors are used to move lumber from one location to another.
- Unscramblers: Unscramblers are used to unscramble lumber that has been jumbled together.
- Sorters: Sorters are used to sort lumber by size or grade.
In addition to these applications, the 81X lumber conveyor chain can also be used in other industries, such as agriculture, mining, and manufacturing.

▍81X Chain Sprockets for 81X Chain (81X Conveyor Chain)
81X chain sprockets are designed to work with 81X chains. Sprockets are toothed wheels that mesh with the links of the chain, providing a positive engagement that drives the chain and any attached load. The 81X chain sprockets for the 81X chain are typically made of high-strength steel or other durable materials, and they come in a range of sizes and tooth counts to accommodate different chain lengths and load requirements.
81X chain, as mentioned earlier, is a heavy-duty chain commonly used in the lumber industry for conveying large and heavy loads of lumber. It is known for its strength, durability, and resistance to wear and tear. The chain is made up of large, sturdy links that are designed to handle high loads and resist deformation.
When selecting 81X chains and 81X chain sprockets, it is important to consider the specific application and load requirements. Factors such as chain length, pitch, and sprocket tooth count will all impact the performance of the system. Proper lubrication and maintenance are also important to ensure maximum chain and sprocket life.
Our 81X chain sprockets there are four standard configurations. A-Plate 81X chain sprockets, B-hub 81X chain sprockets, C-hub 81X chain sprockets, and split 81X chain sprockets. However, we also supply idler sprockets that use bearings or bronze bushings, depending on the sprocket size and application. Below is a chart that shows the standard tooth counts for 81x chain sprockets.
