The 81X series chains were introduced in the early 1900s for heavy-duty industrial and agricultural conveying applications. However, these chains provide an excellent solution for rolling mill applications facing the problem of “standard” roller chain failure. Our 81X Series Roller Chains offer exceptional performance at a value-based price. Our chain includes Fully heat-treated components, solid rollers, solid bushings, and, in most cases, square rivets designed to allow for side loads. We stock standard 81X, heavy and extra heavy duty 81X chains, and roof/hunchback 81X chains.
How To Identify 81X Series Chain
You first want to check if there is a part number on the side of the chain. This will tell you immediately which chain you have. If this information is not on the sidebar of the chain, follow the steps below.
1st: Measure the center of one pin to the center of the next pin. This is commonly referred to as the pitch and represents the dimension P in the diagram above.
2nd: measure the pin diameter, which is represented by dimension D.
3rd: Measure the roller’s diameter, represented by dimension R.
4th: Measure the width of the roller, represented by dimension W.
5th, measure the plate’s thickness, represented by dimension T.
6th: Measure the board height, denoted by dimension H.
Applications of Engineering Class Chain
The engineered chain is a solid workhorse, ideal for high load capacities for many industrial applications that include or require harsh operating conditions. The engineered chain also provides fatigue strength for near-continuous operation. You don’t have to worry about stopping equipment due to poor performance or continuing equipment failure due to overuse. Engineering chains are versatile, working in the food service industry and some of the most challenging jobs on the planet, such as oil drilling, forklift operations, timber applications, road cranes, and elevators. While these applications are often harsh with high temperatures and volumes of sand, dirt, grease, and oil, engineered chains get the job done with high power transfer rates and unmatched durability. Engineered chains are a natural choice when your organization is looking for something to move heavy equipment and handle high shock loads.
Uses of Engineering Class Chains
Food service is just one of many applications of this type of multifunctional engineering chain. They are used in some of the toughest applications, such as oil drilling, operations involving large amounts of sand, dirt and sticky crude. They also saw the use of forklifts that would be subjected to repeated stress and bumps. Engineering chains are the engineer’s first choice when the application requires compact space, the maximum possible amount of power transfer and a high level of durability.
