Rollway Bearing Company was founded in 1908 in Syracuse, New York, and specializes in cylindrical roller bearings and spherical roller bearings for heavy industrial applications. Rollway serves steel mills, paper mills, mining, and power generation equipment markets. Now part of the Koyo/JTEKT organization, Rollway part numbers use a proprietary alpha-numeric system — such as E-series and WS-series — that maps to but does not directly correspond with standard ISO cylindrical roller bearing designations.
