EP Group has increased its business lines to include Power Transmission Units and Comp1nts, Automotive Parts and Materials Handling Systems.welded steel WR78-4 chain & sprocket is manufactured to exceed expectations in working life, strength, and quality. The welded steel style chain & sprocket is 1 of the most popular types of Engineer Class Chain & Sprocket on the market. This is widely due to its effectively productive offset link design. With an ultra-high10sile strength of 29,800 lbs at a low per foot w8 of 4.0 lbs, WR78-4 chain & sprocket makes an excellent and efficient use in whichever application it is used in. What makes our WR78-4 chain & sprocket different is the use of high-grade steel so the core of the comp1nts has great metallurgy. Common applications for WR78-4 welded steel chain & sprocket include heavy-duty conveyors, forestry, grain handling, pulp, paper, and sugar processing. This chain & sprocket is supplied as 10′ coils (30 link strands) and is supplied with 1 heat-treated connecting pin per coil.
WH78-4 vs WR78-4 Chain & Sprocket
WR78-4 and WH78-4 chain & sprocket 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 comp1nts, thus it has a much quicker wear life and a lower10sile strength rating. Because of this we primarily recommend WH78-4 chain & sprocket and supply it at no additional cost!
