Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To match diverse operational dynamics, CHG Bearing supplies M272749TD/M272710 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Engineered according to international ISO boundary plans, CHG Bearing supplies M272749TD/M272710 with a precision bore diameter (d) of 479.425 mm, an outside diameter (D) of 679.45 mm, and a nominal ring width (B) of 238.125 mm. This configuration yields an effective cross-sectional wall thickness of 100.0 mm and an envelope ratio (D/d) of 1.42, delivering compact rigidity for OEM machinery housings.
Built for demanding industrial environments, the M272749TD/M272710 Double Row Tapered Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
The Open Type engineered for M272749TD/M272710 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.
