Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To extend the trouble-free lifespan of CHG Bearing 382952, 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.
To match diverse operational dynamics, CHG Bearing supplies 382952 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.
Beyond standard alloy steel, CHG Bearing can customize the 382952 Four-Row Tapered Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Engineered according to international ISO boundary plans, CHG Bearing supplies 382952 with a precision bore diameter (d) of 260 mm, an outside diameter (D) of 360 mm, and a nominal ring width (B) of 265 mm. This configuration yields an effective cross-sectional wall thickness of 50.0 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
