American Standard Roller Chains Heavy (H) Series based on ISO 606R /Din 8188
American Standard H Series Roller Chains & High Impact Load versions -
H Series Roller Chains are based on the Standard Series Chains, although normally supplied and produced as a riveted chain, they can also be supplied as a cottered type if required?
The only difference from the standard series is the increase in plate thickness!, for example a ASA 60H chain would have the same plate thickness of ASA80, by increasing the plate thickness it improves the capacity to absorb shock loads by 10%. Beside increasing the side plate thickness, other Production Technics can be introduced to provide chains capable of up to 30% Higher for Heavy Duty applications in the Earth Moving & Quarrying Industries?

All provide increase load or Shock Capacity mainly for Earth moving & Quarry applications
Identifying High Impact Load Chains:
This is not easy, as these chains conform to the same nominal sizes as the Standard Series & Heavy Series Chains? Beside the normal dimensions, you will also need to check for?
1-Test for a Harden Pin, with a file?
2-Check for Increased Side Plate Height, not figure of eight? (Be careful not to confuse this with a Straight Side Plate chain?)
3-Check for Interference Fit between Pin & Bush, normally you can not remove the connecting link without a press?

Production Measures that can be included to provide Chains that are more suitable for High Impact Loads:
1- Through Hardened Pins?
2- Shaped Side Plates?
3- Interference Fit Between Pins & Outer Plates?
Precision Roller Chains: as the company offer a combined range, that is produced by a number manufacturers from around the World, they have adopted the following Quality Standards:-
1- All chains have been produced in plant that is Certified to ISO 9001
2- Chains covered by the ISO 606R Standard, will conform to this Standard of Specification and Quality
3- For chains not covered by ISO606R, then we have adopted the appropriate Din 8187 or Din 8188 or Ansi B 29.1 of Specification and Quality Standard.
4- Work standard chains not covered by the above standards will conform to the appropriate Manufacturer's Standard.
