ANSI 80 Roller Chain VS. 16B Roller Chain
Roller chains consist of cylindrical rollers connected by links. The pitch of a roller chain, defined as the distance between the centers of two adjacent rollers, plays a crucial role in determining its size, strength, and application suitability.
The 16B Roller Chain is one of the larger roller chains on the market, designed for heavy-duty applications. With a pitch of 25.4 mm (1 in), the 16B chain is known for its strength and durability.
The 80 Roller Chain follows the ANSI B29.1 standard, which designates it as an imperial pitch chain. Like the 16B, the 80 roller chain has a 25.4 mm (1 in) pitch, making it seem like a potential substitute for the 16B chain. However, there are some differences between 16B roller chain and #80 roller chain.

Metric 16B roller chains are commonly used in demanding machinery like Conveyors, Mining equipment, and Heavy lifts. Due to its robust design, the 16B chain is ideal for applications that require high load-bearing capacity and resistance to wear and fatigue.
However, there are notable differences: 80 roller chains have a smaller width than the 16B chains.
The ANSI 80 roller chains' high strength and solid construction make them suitable for heavy-duty applications involving high loads and operating speeds. The 80 roller chain is widely used in industrial applications, particularly those involving large machinery and high-performance environments.
Are 16B and 80 Roller Chains Interchangeable?
Although the 16B and 80 roller chains have the same pitch size (25.4 mm), there are several key factors to consider when determining if they are interchangeable:
Chain Width
The 16B roller chain tends to be wider than the 80 roller chain due to its larger size and design.
This difference in width can prevent direct interchangeability between the two chains, as the sprockets used for each chain might differ in size and design.
Chain Strength and Load Capacity
The 80 roller chain generally offers greater strength and fatigue resistance than the 16B chain.
This makes the 80 chain better suited for high-load, high-speed applications, while the 16B chain is often used in moderate-load situations.
Chain Performance and Fatigue Resistance
The 80 roller chain is designed to withstand higher operational stresses, making it more suitable for continuous operation under heavy-duty conditions.
The 16B chain is more suited for environments with lower fatigue requirements, making it a better choice for less demanding tasks.
In conclusion, even though the 16B and 80 roller chains both have a pitch size of 25.4 mm (1 in), they are not completely interchangeable. Differences in width, strength, fatigue resistance, and load capacity make swapping them out risky. Using the wrong chain can affect the performance and longevity of your machinery.
To ensure the best results and prevent failure or excessive wear, always check the manufacturer’s specifications when choosing a roller chain for your application. Making the right choice is key to keeping your equipment running smoothly, safely, and reliably.
