This EPT chains, both standard and non-standard, are made of: ○ High quality steels: dimensions and adapted chemical composition for the different chain parts ○ The most efficient manufacturing processes: • Special technique for the production of bushes improving the chain 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 parts: • Shot peening • Surface finishing • Case hardening, carbonitriding, quenching, tempering … • EPT®treatment • Freezing treatment • Corrosion protection coatings (GEOMET, zinc, nickel plating, …)We inspect every piece of bearing by ourselves before delivery.Standard roller chain & sprocket is available with pitches from 1/2 to 3 inches. Chain & Sprocket numbers are determined by multiplying the pitch by 80 (a 1/2 inch pitch chain & sprocket would be a No. 40 chain & sprocket). A hyphenated suffix indicates multiple strands.AK74 Pulley 1-1/8″ bore is directly interchangeable with other manufacturers, is 7.25″ in diameter, is used with A style V-Belts, and is manufactured in accordance with ARPM Standard IP20 for safe operation. What separates this AK74 pulley from the others is that it is made using a high grade-35 cast iron, is phosphate coated, painted, and balanced at the factory. Using the grade 35 cast iron offers a higher10sile strength and is more wear resistant than the more commonly used grade 25. While the phosphate coated and then painted finish adds corrosion resistance to the AK74 pulley. Then, because this pulley is dynamically balanced it runs smoother which gives bearings and other comp1nts of the equipment a longer working life. Additionally, we stock a full line of premium A-Series V-Belts, shafting, key-stock, motors, gearboxes, bearings, and much more!
