Description
The 80H-6 is the heavy duty version of the one inch pitch simplex roller chain, built in 40Mn carbon steel. The H series uses thicker link plates than the standard 80 build, so it carries a higher load in the same pitch and fits the same sprocket envelope. It is the size to specify when a standard 80 chain is running close to its limit, or when shock loading has been stretching chains early.
Product Features
- Heavy duty H series simplex construction on a 25.4 mm (1 in) pitch
- Thicker link plates than the standard series for higher load capacity
- 40Mn carbon steel plates with hardened pins and bushes
- Made to ISO / DIN dimensions for direct interchange
- Original steel finish for lubrication at installation
- 100H-6 and 120H-6 sizes available in the same family
- Supplied by the roll or cut to your run length
Product Advantages
- Higher load capacity without changing pitch or sprockets
- 40Mn steel and hardened pins resist the wear that ends a standard chain early
- A direct swap for a stretched 80 series chain – no redesign needed
- One H series family covers 80, 100 and 120, so spares planning stays simple
- Cut-to-length supply avoids paying for a full roll on a short drive
- Produced and exported from Xiamen with over 40 years of chain experience

Application Scenarios
The H series one inch chain is specified where a standard 80 build is marginal on load or life. Typical applications include:
- Industrial transmission drives running near capacity
- Conveyors and material handling with shock loading
- Machinery repair shops replacing a stretched 80 series chain
- Plant where a standard chain has been failing early
- Heavy duty pump, fan and compressor drives
- Agricultural and construction equipment drives
