Frequently Asked Questions / FAQ
What are the exact dimensions of RUIST NX12Z?
RUIST NX12Z Bearing: bore d = 12 mm, outer diameter D = 21 mm, width/height B = 18 mm. All dimensions follow ISO/DIN standards so it drops into existing housings without modification.
What load ratings does RUIST NX12Z 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 NX12Z typically used?
Bearing of this size are common in electric motors, gearboxes, pumps, conveyors, fans and compressors across heavy-industry plants.
Can RUIST NX12Z replace a SKF, FAG, NSK or TIMKEN unit?
Yes. Because bore 12 mm, OD 21 mm and width 18 mm match ISO dimensions, NX12Z is dimensionally interchangeable with major-brand equivalents. Confirm clearance class (C3/C0) before ordering.
