RUIST H3284 Bearing: bore d = 400 mm, outer diameter D = 420 mm, width/height B = 352 mm. All dimensions follow ISO/DIN standards so it drops into existing housings without modification.
What load ratings does RUIST H3284 carry?
Dynamic load rating Cr = — kN and static load rating Cor = — kN. These figures let you calculate the L10 service life under your actual radial and axial loads.
Where is RUIST H3284 typically used?
Bearing of this size are common in electric motors, gearboxes, pumps, conveyors, fans and compressors across heavy-industry plants.
