What load ratings does RUIST H3964 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 H3964 typically used?
Bearing of this size are common in electric motors, gearboxes, pumps, conveyors, fans and compressors across heavy-industry plants.
