Matching WH78-4 / WR78-4 Chain | Welded Steel Mill Chain
Our welded steel WR78-4 chain is manufactured to exceed expectations in working life, strength, and quality. The welded steel style chain is one of the most popular types of Engineer Class chains on the market. This is widely due to its effectively productive offset link design. With an ultra-high tensile strength of 29,800 lbs at a low per-foot weight of 4.0 lbs, the WR78-4 chain makes excellent and efficient use in whichever application it is used in. What makes our WR78-4 chain different is the use of high-grade steel so the core of the components has great metallurgy. Common applications for WR78-4 welded steel chains include heavy-duty conveyors, forestry, grain handling, pulp, paper, and sugar processing. This chain is supplied as 10′ coils (30 link strands) and is supplied with one heat-treated connecting pin per coil.
WH78-4 Chain vs WR78-4 Chain
WR78-4 and WH78-4 chains directly interchange with each other dimensionally and are both equally as popular. However, when taking a closer look there are differences. WR78-4 does not implement fully heat-treated components. Thus, it has a much quicker wear life and a lower tensile strength rating. Because of this we primarily recommend the WH78-4 chain and supply it at no additional cost!
WR78-4 strength: 29,800 LBS vs WH78-4 Strength: 34,000 LBS
