M274149/M274110D 711.2 mm 501.65 mm Frequently Asked Questions about M274149/M274110D Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects M274149/M274110D to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Built for demanding industrial environments, the M274149/M274110D 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 CHG Bearing M274149/M274110D is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
To match diverse operational dynamics, CHG Bearing supplies M274149/M274110D 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.
