On the whole, conveyor chains are operated for longer distances and at lower speeds than transmission chains. Accordingly, although the pins, bushings and rollers are left unchanged, along with the plate pitch is doubled to reduce the amount of sprocket teeth engaged with the chain to half, the put on of pins, bushings and rollers is compact since the chain velocity is very low. Double Pitch Chains, conform to ANSI typical and “Ultimate Life Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains are also offered.
Double pitch chain with resin rollers
This is a Double Pitch Chain with R Roller made from resin, which generates much less noise and lighter excess weight in contrast with steel rollers. Thus, the chain is suitable to get a conveyor program made to operate quietly and convey light-weight articles. Because the components aside from rollers are made of steel, the typical tensile power of the resin roller chain could be the exact same as that of a steel roller chain. Nevertheless, the “maximum allowable load” from the chain ought to be stored decrease, as proven while in the following table, to prevent injury to the plastic rollers by 
the pressure from the engagement with sprockets.
The “Allowable load of resin rollers” refers for the allowable load acting when conveyed articles press the resin rollers traveling to the floor surface such as guid rails.
Big roller (R) and small rollers (S)
Given that double pitch chains are often used for conveying items on the horizontal floor, chains developed for this objective have increased roller diameter equal to that of single pitch chains with the exact same pitch for enhanced load capability and lower traveling resistance. These rollers with more substantial outer diameter are known as “large rollers”, as well as regular rollers are named “small rollers”.
In this catalog, big rollers are expressed as R Roller, and small rollers as S Roller.
Designation of double pitch chains
A double pitch chain is designated, as inside the following instance, dependant on the nominal quantity of the single pitch chain it can be dependant on.
Connecting back links
For the connecting links of double pitch chains of all sizes, the connecting plates and connecting pins are clearance-fitted. For C2060H or smaller, the spring clip form (R connecting website link) is conventional. For C2080H or larger, the cotter type (C connecting hyperlink) is conventional. Connecting hyperlinks with an attachment, top rated roller or side roller are also out there.
