This The continued expansion of our ball bearings, mounted units and power transmission product lines, along with our attention to detail and quality, has allowed EPG to gain broad acceptance to a diverse customer base.EPG has set up a complete set of quality management system which is provided with advanced inspection and chain & sprocket test equipment. EPT chain & sprockets, both standard and non-standard, are made of: ○ High quality steels: dimensions and adapted chemical composition for the different chain & sprocket parts ○ The most efficient manufacturing processes: • Special technique for the production of bushes improving the chain & sprocket wear resistance ( EPT know-how) • Plates produced by multi-stage processing tools ensuring a regular pitch ( EPT technology) ○ Adequate mechanical and heat treatments of chain & sprocket parts: • Shot peening • Surface finishing • replacement of Case hardening, carbonitriding, quenching, tempering … • EPT®treatment • Freezing treatment • Corrosion protection coatings (GEOMET, zinc, nickel plating, …)085B31 sprocket with a stock bore is a metric roller chain & sprocket sprocket manufactured under ISO and British Standard 228. Our 085B31 sprockets are made with reliability and performance in mind, so we use high-quality carbon steel (CS) and have the sprocket precision cut to ensure maximum performance and wear life. Besides the stock bore we also can supply these sprockets with a specific plain or finished (has key-way and set screws) bore size. We also offer upgrades on our 085B31 sprockets such as black-oxide coatings and heat-treated hardened teeth, though hardened tooth sprockets are typically not utilized on tooth counts past 30. Besides the 31 tooth sprocket, we also stock a high-quality 085 roller chain & sprocket
