This Standard roller chain is available with pitches from 1/2 to 3 inches. Chain numbers are determined by multiplying the pitch by 80 (a 1/2 inch pitch chain would be a No. 40 chain). A hyphenated suffix indicates multiple strands.The group has taken part in the making and revising of ISO/TC100 international chain & sprocket standard several years in success and hosted the 16th ISO/TC100 replacement of International annual meeting in 2004. 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, …)40BS58 sprocket features a 5/8″ finished bore including a key-way and 2 setscrews. It is a durable, high quality, and precision sprocket that fully meets all ANSI Standards which insures proper contact between the #40 roller chain & sprocket and sprocket thus preventing premature wear or breakage.
