Frequently Asked Questions / FAQ
What are the exact dimensions of RAYSDE 812/630M?
RAYSDE 812/630M Thrust Ball Bearing: bore d = 630 mm, outer diameter D = 850 mm, width/height B = 175 mm. All dimensions follow ISO/DIN standards so it drops into existing housings without modification.
What load ratings does RAYSDE 812/630M carry?
Dynamic load rating Cr = 4800 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 RAYSDE 812/630M typically used?
Thrust Ball Bearing of this size are common in electric motors, gearboxes, pumps, conveyors, fans and compressors across heavy-industry plants.
Can RAYSDE 812/630M replace a SKF, FAG, NSK or TIMKEN unit?
Yes. Because bore 630 mm, OD 850 mm and width 175 mm match ISO dimensions, 812/630M is dimensionally interchangeable with major-brand equivalents. Confirm clearance class (C3/C0) before ordering.
