M255448/M255410D 406.4 mm 288.925 mm Frequently Asked Questions about M255448/M255410D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing M255448/M255410D Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF M255448/M255410D, FAG M255448/M255410D, NSK M255448/M255410D. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
When fitting M255448/M255410D over a 288.925 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
To ensure optimum performance of CHG Bearing M255448/M255410D Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 288.925 mm bore. For the 406.4 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Every production batch of CHG Bearing M255448/M255410D Double Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
