What are the exact dimensions of RUIST H309X?
RUIST H309X Bearing: bore d = 40 mm, outer diameter D = 45 mm, width/height B = 39 mm. All dimensions follow ISO/DIN standards so it drops into existing housings without modification.
What load ratings does RUIST H309X 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 H309X typically used?
Bearing of this size are common in electric motors, gearboxes, pumps, conveyors, fans and compressors across heavy-industry plants.
Can RUIST H309X replace a SKF, FAG, NSK or TIMKEN unit?
