Frequently Asked Questions / FAQ
What are the exact dimensions of RUIST H306X?
RUIST H306X Bearing: bore d = 25 mm, outer diameter D = 30 mm, width/height B = 31 mm. All dimensions follow ISO/DIN standards so it drops into existing housings without modification.
What load ratings does RUIST H306X 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 H306X typically used?
Bearing of this size are common in electric motors, gearboxes, pumps, conveyors, fans and compressors across heavy-industry plants.
Can RUIST H306X replace a SKF, FAG, NSK or TIMKEN unit?
Yes. Because bore 25 mm, OD 30 mm and width 31 mm match ISO dimensions, H306X is dimensionally interchangeable with major-brand equivalents. Confirm clearance class (C3/C0) before ordering.
