RUIST 342/S/332 Tapered Roller Bearing: bore d = 42.875 mm, outer diameter D = 80 mm, width/height B = 21 mm. All dimensions follow ISO/DIN standards so it drops into existing housings without modification.
Dynamic load rating Cr = 73.6 kN and static load rating Cor = 83.4 kN. These figures let you calculate the L10 service life under your actual radial and axial loads.
Tapered Roller Bearing of this size are common in electric motors, gearboxes, pumps, conveyors, fans and compressors across heavy-industry plants.
Yes. Because bore 42.875 mm, OD 80 mm and width 21 mm match ISO dimensions, 342/S/332 is dimensionally interchangeable with major-brand equivalents. Confirm clearance class (C3/C0) before ordering.
