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?
Information Bar -

-> Special Profiles to order
 Increased Capacity Types:
1-Through Harden Pins!
2- Shaped side Plates!
3- Interference Fit between Pins & side Plates!
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?
