Overview
The H Class Mill H78 Chain is a heavy-duty chain used mainly in the lumber and paper mill industries. It is designed to handle heavy loads in harsh environments, making it a reliable choice for demanding industrial applications.
Chain Specifications
Chain Size and Pitch
The H78 chain has a pitch of 3 inches, and its size is determined by the number of pitches in a given length. The chain is available in standard and heavy series.
Breaking Load
The breaking load of the H78 chain depends on the size and series. The standard series has a breaking load of 125,000 pounds, while the heavy series has a breaking load of 187,000 pounds.
Wear Life
The wear life of the H78 chain is affected by factors such as lubrication and maintenance. Proper lubrication and maintenance can significantly extend the wear life of the chain, reducing downtime and maintenance costs.

Chain Materials and Construction
Material
The H78 chain is made of high-grade alloy steel for strength and durability. The use of high-grade alloy steel in the construction of the chain ensures the chain can withstand heavy loads and harsh environments.
Construction
The H78 chain is constructed using a quad staked pin design for added strength and durability. The pins are staked on all four sides to ensure they remain securely in place, reducing the risk of chain failure.

Chain Applications
The H78 chain is primarily used in the lumber and paper mill industries, where heavy loads and harsh environments are common. It is also used in other industrial applications where heavy loads are required.
Chain Maintenance
Maintenance of the H78 chain is critical to ensure its longevity and reliable performance. Proper lubrication, tension adjustment, and regular inspection can help prevent premature wear and failure, reducing downtime and maintenance costs.

Sprockets for H78 Chains
The H78 chain is designed to work with compatible sprockets to ensure optimal performance. The sprockets are made of high-grade alloy steel and are precision machined to ensure a perfect fit with the chain.
