What Is the Difference Between 35 Chain 40 Chain
Roller chains are most commonly used on bicycles, automobile engines and heavy machinery for the transmission of power. They come in a variety of sizes to meet almost any application. The larger the size of chain, the larger the roller diameter, pitch and tensile strength the chain is rated for. Choosing the right chain for your application is important for safety and functionality.
Roller Chain Terms
The chains pitch is the distance between the center of the neighboring rollers; its diameter is the width between the link side plates. The digit furthest to the right in the chains number denotes its type: 0 for a normal chain, 1 means a lightweight chain and 5 for a rollerless bushing chain. If the chain number ends with an "H" it is a heavyweight chain.
35 Chain
The 35 chain is a rollerless type chain. It has a pitch of 0.375 inches and diameter of 0.2 inches. It is rated for a tensile strength of 1,758 pounds and a working load of 480 pounds.
40 Chain
The 40 chain is a normal, roller-type chain. It has a pitch of 0.5 inches and a diameter of 0.312 inches. It is rated for a tensile strength of 3,125 pounds and a working load of 810 pounds.
Differences
The main difference between the 35 and the 40 chain is that one is rollerless and the other has rollers. The two chains also have different pitches and diameters, which will limit their interoperability. Additionally, the 40 chain is rated for a significantly higher tensile strength and working load than the 35.
