What is a double strand chain?
The double-strand roller chain, commonly called a duplex roller chain, consists of two rows of single-strand roller chains manufactured together. It provides lots of practicality due to its high impact strength coupled with a relatively small form factor.
What are duplex chains used for?
Roller chain or bush roller chain is most commonly used for transmission of mechanical power. It is simple, reliable, and efficient. It is usually measured from the centres on each link.
How do I identify chain size?
To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.
What are the applications of silent chains?
From the 1930s forward, silent chain was frequently used in a variety of industrial applications including: drives in paper and textile mills, flour and feed mills, printing presses, industrial fans and blowers, pumps, and machine tools. It was also commonly used as a timing chain in early automobile engines.
What is the difference between simplex and duplex chain?
In a simplex mode of transmission, only one of the two devices on the link can transmit the signal, and the other can only receive but can not send back the signal in reverse. In a half duplex mode, both the devices connected on the link can transmit the signal but only one device can transmit at a time.
What is simplex and duplex chain?
Simplex and duplex roller chains with a 3/8″ pitch are used primarily in timing drives, oil pump drives and drives for auxiliary units, especially for petrol engines. Owing to its smaller pitch, a roller chain with an 8 mm pitch cuts the weight and consequently reduces the centrifugal forces and impact speed.
How are chains numbered?
The first number is the pitch size in 1/8 inch, ie 4/8 = 1/2 inch pitch. The second number refers to the chain being a roller chain, 0 = roller chain. A 5 replacing the 0 would indicate a bush chain. The suffix, as with European standard chain, refers to the number of strands in the chain, that is 2 = duplex chain.
What is double pitch roller chain?
Double Pitch Roller Chain has the same basic construction as Standard Roller Chain, but double pitch means the chain pitch is twice as long, has flat-shaped link plates, and longer attachments. This series is regulated by ANSI B29.
What is the strongest roller chain?
Super #80 roller chain is apart of the SH Super High Strength Series roller chain section and is one of the strongest, most durable ANSI 80 roller chain in the world! the Super Strength Pins of this chain are constructed of a special high-strength alloy are through hardened.
