Double pitch chain

Usually, conveyor chains are operated for longer distances and at lower speeds than transmission chains. Accordingly, although the pins, bushings and rollers are left unchanged, and also the plate pitch is doubled to reduce the quantity of sprocket teeth engaged with the chain to half, the wear of pins, bushings and rollers is little since the chain velocity is lower. Double Pitch Chains, conform to ANSI regular and “Ultimate Lifestyle Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains may also be available.
Double pitch chain with resin rollers
This can be a Double Pitch Chain with R Roller made from resin, which generates much less noise and lighter weight in contrast with steel rollers. So, the chain is ideal for any conveyor process intended to operate quietly and convey light-weight articles or blog posts. Since the parts besides rollers are made of steel, the common tensile power of the resin roller chain will be the similar as that of a steel roller chain. Nonetheless, the “maximum allowable load” of the chain really should be kept lower, as proven in the following table, to prevent injury to your plastic rollers through the strain in the engagement with sprockets.
The “Allowable load of resin rollers” refers for the allowable load acting when conveyed content articles press the resin rollers traveling around the floor surface this kind of as guid rails.
Big roller (R) and modest rollers (S)
Considering the fact that double pitch chains are often made use of for conveying solutions on the horizontal floor, chains developed for this purpose have improved roller diameter equal to that of single pitch chains from the identical pitch for improved load capacity and reduced traveling resistance. These rollers with larger outer diameter are called “large rollers”, as well as the standard rollers are identified as “small rollers”.
In this catalog, substantial rollers are expressed as R Roller, and tiny rollers as S Roller.
Designation of double pitch chains
A double pitch chain is designated, as while in the following example, depending on the nominal amount of the single pitch chain it is actually based upon.
Connecting hyperlinks
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 kind (R connecting link) is conventional. For C2080H or larger, the cotter variety (C connecting link) is conventional. Connecting links with an attachment, leading roller or side roller are also available.
