M275349D/M275310 736.6 mm 519.113 mm Frequently Asked Questions about M275349D/M275310 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts M275349D/M275310 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies M275349D/M275310 with a precision bore diameter (d) of 519.113 mm, an outside diameter (D) of 736.6 mm, and a nominal ring width (B) of 258.763 mm. This configuration yields an effective cross-sectional wall thickness of 108.7 mm and an envelope ratio (D/d) of 1.42, delivering compact rigidity for OEM machinery housings.
Sourcing M275349D/M275310 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Double Row Tapered Roller Bearings.
The Open Type engineered for M275349D/M275310 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
