Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 46T443011 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.
To extend the trouble-free lifespan of CHG Bearing 46T443011, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
Engineered according to international ISO boundary plans, CHG Bearing supplies 46T443011 with a precision bore diameter (d) of 220 mm, an outside diameter (D) of 300 mm, and a nominal ring width (B) of 109 mm. This configuration yields an effective cross-sectional wall thickness of 40.0 mm and an envelope ratio (D/d) of 1.36, delivering compact rigidity for OEM machinery housings.
To match diverse operational dynamics, CHG Bearing supplies 46T443011 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.
