Description
American Standard Roller Chains Heavy (H) Series based on ISO 606R /Din 8188
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.
Production Measures that can be included to provide Chains that are more suitable for High Impact Loads :-
- Through Hardened Pins
- Shaped Side Plates
- 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 :-
- All chains have been produced in plant that is Certified to ISO 9001.
- Chains covered by the ISO 606R Standard, will conform to this Standard of Specification and Quality.
- 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.
- Work standard chains not covered by the above standards will conform to the appropriate Manufacturer’s Standard.

Tips
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 :-
- Test for a Harden Pin, with a file.
- Check for Increased Side Plate Height, not figure of eight (Be careful not to confuse this with a Straight Side Plate chain).
- Check for Interference Fit between Pin & Bush, normally you can not remove the connecting link without a press.
