Double pitch chain

Generally, conveyor chains are operated for longer distances and at lower speeds than transmission chains. Accordingly, while the pins, bushings and rollers are left unchanged, as well as the plate pitch is doubled to reduce the quantity of sprocket teeth engaged using the chain to half, the put on of pins, bushings and rollers is small since the chain velocity is lower. Double Pitch Chains, conform to ANSI standard and “Ultimate Existence Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains may also be available.
Double pitch chain with resin rollers
It is a Double Pitch Chain with R Roller made of resin, which generates significantly less noise and lighter fat compared with steel rollers. Thus, the chain is suitable for any conveyor method developed to operate quietly and convey light-weight content articles. Since the elements aside from rollers are made from steel, the common tensile power of a resin roller chain would be the very same as that of the steel roller chain. However, the “maximum allowable load” of your chain needs to be stored lower, as proven during the following table, to avoid harm to the plastic rollers from the stress in the engagement with sprockets.
The “Allowable load of resin rollers” refers for the allowable load acting when conveyed articles press the resin rollers traveling on the floor surface such as guid rails.
Substantial roller (R) and compact rollers (S)
Considering the fact that double pitch chains are often employed for conveying items on a horizontal floor, chains intended for this purpose have greater roller diameter equal to that of single pitch chains on the exact same pitch for elevated load capability and lower traveling resistance. These rollers with bigger outer diameter are named “large rollers”, plus the normal rollers are referred to as “small rollers”.
In this catalog, significant rollers are expressed as R Roller, and tiny rollers as S Roller.
Designation of double pitch chains
A double pitch chain is designated, as during the following illustration, depending on the nominal number of the single pitch chain it really is based on.
Connecting links
To 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 hyperlink) is common. For C2080H or larger, the cotter sort (C connecting website link) is typical. Connecting backlinks with an attachment, major roller or side roller are also offered.
