M255449TD/M255410 406.4 mm 288.925 mm Frequently Asked Questions about M255449TD/M255410 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model M255449TD/M255410 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 288.925 mm) and steep thermal gradients between inner and outer rings.
Every production batch of CHG Bearing M255449TD/M255410 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.
Quality starts with raw material selection: CHG Bearing crafts M255449TD/M255410 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for M255449TD/M255410, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
