According to AISI (American Iron and Steel Institute), the U.S. steel industry operates about 100 steelmaking facilities, producing nearly 90 million tons of steel annually. The steel industry directly employs nearly 150,000 employees directly or indirectly supports about a million jobs. Largely due to technological advancements, labor productivity has increased from an average of 10.1 man-hours per finished ton in the early 1980’s to 1.9 man-hours per finished ton today.
Many of the OEMs that produce steelmaking equipment are based in Europe, so they naturally provide a lot of mounted bearings and mechanical power transmission products that are designed using metric dimensional standards. PTI stocks many of these components at our facility in Charlotte, North Carolina – USA. This includes European style split Plummer block housings and related accessories (bearings, adapters, seals, etc.). We also stock inch-dimensioned SAF (cast iron), SAFD (ductile iron) and SAFS (cast steel) pillow blocks and accessories. Through our partnership with Eich, PTI provides high capacity spring wound roller bearings for use in continuous caster rolls. Manufactured in Germany, Eich bearings are known globally as the OEM’s choice for use on continuous casters due to their ability handle extreme temperatures and handle extremely high loads while having a compact design.
