Double pitch chain

Generally, conveyor chains are operated for longer distances and at reduce speeds than transmission chains. Accordingly, while the pins, bushings and rollers are left unchanged, and the plate pitch is doubled to reduce the quantity of sprocket teeth engaged with the chain to half, the dress in of pins, bushings and rollers is little because the chain velocity is lower. Double Pitch Chains, conform to ANSI common and “Ultimate Lifestyle Chain Series” and “Environment Resistant Chain Series”, as are single pitch chains may also be readily available.
Double pitch chain with resin rollers
This is a Double Pitch Chain with R Roller manufactured from resin, which generates less noise and lighter weight compared with steel rollers. Hence, the chain is ideal for any conveyor system designed to operate quietly and convey light-weight posts. Because the elements besides rollers are made of steel, the common tensile strength of a resin roller chain would be the exact same as that of the steel roller chain. Having said that, the “maximum allowable load” of your chain need to be stored reduced, as proven from the following table, to prevent injury for the plastic rollers through the strain through the engagement with sprockets.
The “Allowable load of resin rollers” refers on the allowable load acting when conveyed articles press the resin rollers traveling to the floor surface such as guid rails.
Large roller (R) and small rollers (S)
Due to the fact double pitch chains are frequently made use of for conveying solutions on a horizontal floor, chains developed for this function have greater roller diameter equal to that of single pitch chains with the identical pitch for greater load capacity and reduced traveling resistance. These rollers with more substantial outer diameter are named “large rollers”, as well as standard rollers are identified as “small rollers”.
In this catalog, significant rollers are expressed as R Roller, and compact rollers as S Roller.
Designation of double pitch chains
A double pitch chain is designated, as from the following example, based on the nominal variety of the single pitch chain it is actually depending on.
Connecting backlinks
For your connecting backlinks of double pitch chains of all sizes, the connecting plates and connecting pins are clearance-fitted. For C2060H or smaller sized, the spring clip type (R connecting hyperlink) is normal. For C2080H or greater, the cotter style (C connecting website link) is regular. Connecting backlinks with an attachment, major roller or side roller can also be readily available.
