Frequently Asked Questions / FAQ
What are the exact dimensions of RAYSDE 51148M?
RAYSDE 51148M Thrust Ball Bearing: bore d = 240 mm, outer diameter D = 300 mm, width/height B = 45 mm. All dimensions follow ISO/DIN standards so it drops into existing housings without modification.
What load ratings does RAYSDE 51148M carry?
Dynamic load rating Cr = 234 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 51148M 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 51148M replace a SKF, FAG, NSK or TIMKEN unit?
Yes. Because bore 240 mm, OD 300 mm and width 45 mm match ISO dimensions, 51148M is dimensionally interchangeable with major-brand equivalents. Confirm clearance class (C3/C0) before ordering.
