Rollway Cylindrical Roller Bearings Guide
Product Description
The Rollway MU-138 Cylindrical Radial Roller Bearing features a separable two-piece inner ring with a removable flange plate, a double-flanged outer ring, crowned cylindrical rollers, and a precision-engineered retainer. Manufactured from through-hardened bearing-grade steel, its precision-ground raceways and crowned rollers provide high radial load capacity while reducing edge stresses. The four-flange design ensures axial location in both directions and supports light axial loads, offering stable performance under demanding operating conditions. The MU-138 bearing is suitable for industrial gearboxes, pumps, and heavy-duty machinery requiring combined radial support and axial positioning, meeting the demanding requirements of the United States industrial market.
